+
+ The complete solution for [node.js](http://nodejs.org) command-line interfaces, inspired by Ruby's [commander](https://github.com/commander-rb/commander).
+ [API documentation](http://tj.github.com/commander.js/)
+
+
+## Installation
+
+ $ npm install commander
+
+## Option parsing
+
+Options with commander are defined with the `.option()` method, also serving as documentation for the options. The example below parses args and options from `process.argv`, leaving remaining args as the `program.args` array which were not consumed by options.
+
+```js
+#!/usr/bin/env node
+
+/**
+ * Module dependencies.
+ */
+
+var program = require('commander');
+
+program
+ .version('0.1.0')
+ .option('-p, --peppers', 'Add peppers')
+ .option('-P, --pineapple', 'Add pineapple')
+ .option('-b, --bbq-sauce', 'Add bbq sauce')
+ .option('-c, --cheese [type]', 'Add the specified type of cheese [marble]', 'marble')
+ .parse(process.argv);
+
+console.log('you ordered a pizza with:');
+if (program.peppers) console.log(' - peppers');
+if (program.pineapple) console.log(' - pineapple');
+if (program.bbqSauce) console.log(' - bbq');
+console.log(' - %s cheese', program.cheese);
+```
+
+Short flags may be passed as a single arg, for example `-abc` is equivalent to `-a -b -c`. Multi-word options such as "--template-engine" are camel-cased, becoming `program.templateEngine` etc.
+
+Note that multi-word options starting with `--no` prefix negate the boolean value of the following word. For example, `--no-sauce` sets the value of `program.sauce` to false.
+
+```js
+#!/usr/bin/env node
+
+/**
+ * Module dependencies.
+ */
+
+var program = require('commander');
+
+program
+ .option('--no-sauce', 'Remove sauce')
+ .parse(process.argv);
+
+console.log('you ordered a pizza');
+if (program.sauce) console.log(' with sauce');
+else console.log(' without sauce');
+```
+
+To get string arguments from options you will need to use angle brackets <> for required inputs or square brackets [] for optional inputs.
+
+e.g. ```.option('-m --myarg [myVar]', 'my super cool description')```
+
+Then to access the input if it was passed in.
+
+e.g. ```var myInput = program.myarg```
+
+**NOTE**: If you pass a argument without using brackets the example above will return true and not the value passed in.
+
+
+## Version option
+
+Calling the `version` implicitly adds the `-V` and `--version` options to the command.
+When either of these options is present, the command prints the version number and exits.
+
+ $ ./examples/pizza -V
+ 0.0.1
+
+If you want your program to respond to the `-v` option instead of the `-V` option, simply pass custom flags to the `version` method using the same syntax as the `option` method.
+
+```js
+program
+ .version('0.0.1', '-v, --version')
+```
+
+The version flags can be named anything, but the long option is required.
+
+## Command-specific options
+
+You can attach options to a command.
+
+```js
+#!/usr/bin/env node
+
+var program = require('commander');
+
+program
+ .command('rm <dir>')
+ .option('-r, --recursive', 'Remove recursively')
+ .action(function (dir, cmd) {
+ console.log('remove ' + dir + (cmd.recursive ? ' recursively' : ''))
+ })
+
+program.parse(process.argv)
+```
+
+A command's options are validated when the command is used. Any unknown options will be reported as an error. However, if an action-based command does not define an action, then the options are not validated.
+
+## Coercion
+
+```js
+function range(val) {
+ return val.split('..').map(Number);
+}
+
+function list(val) {
+ return val.split(',');
+}
+
+function collect(val, memo) {
+ memo.push(val);
+ return memo;
+}
+
+function increaseVerbosity(v, total) {
+ return total + 1;
+}
+
+program
+ .version('0.1.0')
+ .usage('[options] <file ...>')
+ .option('-i, --integer <n>', 'An integer argument', parseInt)
+ .option('-f, --float <n>', 'A float argument', parseFloat)
+ .option('-r, --range <a>..<b>', 'A range', range)
+ .option('-l, --list <items>', 'A list', list)
+ .option('-o, --optional [value]', 'An optional value')
+ .option('-c, --collect [value]', 'A repeatable value', collect, [])
+ .option('-v, --verbose', 'A value that can be increased', increaseVerbosity, 0)
+ .parse(process.argv);
+
+console.log(' int: %j', program.integer);
+console.log(' float: %j', program.float);
+console.log(' optional: %j', program.optional);
+program.range = program.range || [];
+console.log(' range: %j..%j', program.range[0], program.range[1]);
+console.log(' list: %j', program.list);
+console.log(' collect: %j', program.collect);
+console.log(' verbosity: %j', program.verbose);
+console.log(' args: %j', program.args);
+```
+
+## Regular Expression
+```js
+program
+ .version('0.1.0')
+ .option('-s --size <size>', 'Pizza size', /^(large|medium|small)$/i, 'medium')
+ .option('-d --drink [drink]', 'Drink', /^(coke|pepsi|izze)$/i)
+ .parse(process.argv);
+
+console.log(' size: %j', program.size);
+console.log(' drink: %j', program.drink);
+```
+
+## Variadic arguments
+
+ The last argument of a command can be variadic, and only the last argument. To make an argument variadic you have to
+ append `...` to the argument name. Here is an example:
+
+```js
+#!/usr/bin/env node
+
+/**
+ * Module dependencies.
+ */
+
+var program = require('commander');
+
+program
+ .version('0.1.0')
+ .command('rmdir <dir> [otherDirs...]')
+ .action(function (dir, otherDirs) {
+ console.log('rmdir %s', dir);
+ if (otherDirs) {
+ otherDirs.forEach(function (oDir) {
+ console.log('rmdir %s', oDir);
+ });
+ }
+ });
+
+program.parse(process.argv);
+```
+
+ An `Array` is used for the value of a variadic argument. This applies to `program.args` as well as the argument passed
+ to your action as demonstrated above.
+
+## Specify the argument syntax
+
+```js
+#!/usr/bin/env node
+
+var program = require('commander');
+
+program
+ .version('0.1.0')
+ .arguments('<cmd> [env]')
+ .action(function (cmd, env) {
+ cmdValue = cmd;
+ envValue = env;
+ });
+
+program.parse(process.argv);
+
+if (typeof cmdValue === 'undefined') {
+ console.error('no command given!');
+ process.exit(1);
+}
+console.log('command:', cmdValue);
+console.log('environment:', envValue || "no environment given");
+```
+Angled brackets (e.g. `<cmd>`) indicate required input. Square brackets (e.g. `[env]`) indicate optional input.
+
+## Git-style sub-commands
+
+```js
+// file: ./examples/pm
+var program = require('commander');
+
+program
+ .version('0.1.0')
+ .command('install [name]', 'install one or more packages')
+ .command('search [query]', 'search with optional query')
+ .command('list', 'list packages installed', {isDefault: true})
+ .parse(process.argv);
+```
+
+When `.command()` is invoked with a description argument, no `.action(callback)` should be called to handle sub-commands, otherwise there will be an error. This tells commander that you're going to use separate executables for sub-commands, much like `git(1)` and other popular tools.
+The commander will try to search the executables in the directory of the entry script (like `./examples/pm`) with the name `program-command`, like `pm-install`, `pm-search`.
+
+Options can be passed with the call to `.command()`. Specifying `true` for `opts.noHelp` will remove the subcommand from the generated help output. Specifying `true` for `opts.isDefault` will run the subcommand if no other subcommand is specified.
+
+If the program is designed to be installed globally, make sure the executables have proper modes, like `755`.
+
+### `--harmony`
+
+You can enable `--harmony` option in two ways:
+* Use `#! /usr/bin/env node --harmony` in the sub-commands scripts. Note some os version don’t support this pattern.
+* Use the `--harmony` option when call the command, like `node --harmony examples/pm publish`. The `--harmony` option will be preserved when spawning sub-command process.
+
+## Automated --help
+
+ The help information is auto-generated based on the information commander already knows about your program, so the following `--help` info is for free:
+
+```
+$ ./examples/pizza --help
+Usage: pizza [options]
+
+An application for pizzas ordering
+
+Options:
+ -h, --help output usage information
+ -V, --version output the version number
+ -p, --peppers Add peppers
+ -P, --pineapple Add pineapple
+ -b, --bbq Add bbq sauce
+ -c, --cheese <type> Add the specified type of cheese [marble]
+ -C, --no-cheese You do not want any cheese
+```
+
+## Custom help
+
+ You can display arbitrary `-h, --help` information
+ by listening for "--help". Commander will automatically
+ exit once you are done so that the remainder of your program
+ does not execute causing undesired behaviors, for example
+ in the following executable "stuff" will not output when
+ `--help` is used.
+
+```js
+#!/usr/bin/env node
+
+/**
+ * Module dependencies.
+ */
+
+var program = require('commander');
+
+program
+ .version('0.1.0')
+ .option('-f, --foo', 'enable some foo')
+ .option('-b, --bar', 'enable some bar')
+ .option('-B, --baz', 'enable some baz');
+
+// must be before .parse() since
+// node's emit() is immediate
+
+program.on('--help', function(){
+ console.log('')
+ console.log('Examples:');
+ console.log(' $ custom-help --help');
+ console.log(' $ custom-help -h');
+});
+
+program.parse(process.argv);
+
+console.log('stuff');
+```
+
+Yields the following help output when `node script-name.js -h` or `node script-name.js --help` are run:
+
+```
+Usage: custom-help [options]
+
+Options:
+ -h, --help output usage information
+ -V, --version output the version number
+ -f, --foo enable some foo
+ -b, --bar enable some bar
+ -B, --baz enable some baz
+
+Examples:
+ $ custom-help --help
+ $ custom-help -h
+```
+
+## .outputHelp(cb)
+
+Output help information without exiting.
+Optional callback cb allows post-processing of help text before it is displayed.
+
+If you want to display help by default (e.g. if no command was provided), you can use something like:
+
+```js
+var program = require('commander');
+var colors = require('colors');
+
+program
+ .version('0.1.0')
+ .command('getstream [url]', 'get stream URL')
+ .parse(process.argv);
+
+if (!process.argv.slice(2).length) {
+ program.outputHelp(make_red);
+}
+
+function make_red(txt) {
+ return colors.red(txt); //display the help text in red on the console
+}
+```
+
+## .help(cb)
+
+ Output help information and exit immediately.
+ Optional callback cb allows post-processing of help text before it is displayed.
+
+
+## Custom event listeners
+ You can execute custom actions by listening to command and option events.
+
+```js
+program.on('option:verbose', function () {
+ process.env.VERBOSE = this.verbose;
+});
+
+// error on unknown commands
+program.on('command:*', function () {
+ console.error('Invalid command: %s\nSee --help for a list of available commands.', program.args.join(' '));
+ process.exit(1);
+});
+```
+
+## Examples
+
+```js
+var program = require('commander');
+
+program
+ .version('0.1.0')
+ .option('-C, --chdir <path>', 'change the working directory')
+ .option('-c, --config <path>', 'set config path. defaults to ./deploy.conf')
+ .option('-T, --no-tests', 'ignore test hook');
+
+program
+ .command('setup [env]')
+ .description('run setup commands for all envs')
+ .option("-s, --setup_mode [mode]", "Which setup mode to use")
+ .action(function(env, options){
+ var mode = options.setup_mode || "normal";
+ env = env || 'all';
+ console.log('setup for %s env(s) with %s mode', env, mode);
+ });
+
+program
+ .command('exec <cmd>')
+ .alias('ex')
+ .description('execute the given remote cmd')
+ .option("-e, --exec_mode <mode>", "Which exec mode to use")
+ .action(function(cmd, options){
+ console.log('exec "%s" using %s mode', cmd, options.exec_mode);
+ }).on('--help', function() {
+ console.log('');
+ console.log('Examples:');
+ console.log('');
+ console.log(' $ deploy exec sequential');
+ console.log(' $ deploy exec async');
+ });
+
+program
+ .command('*')
+ .action(function(env){
+ console.log('deploying "%s"', env);
+ });
+
+program.parse(process.argv);
+```

+Sanitize untrusted CSS with a configuration specified by a Whitelist. 根据白名单过滤CSS
+
+
+## 安装
+
+```bash
+$ npm install cssfilter --save
+```
+
+
+## 使用方法
+
+```javascript
+var cssfilter = require('cssfilter');
+var css = cssfilter('position:fixed; /* this is comments */ width:100px; height:100px; background:#aaa;');
+console.log(css);
+// 输出:width:100px; height:100px; background:#aaa;
+// 因为position不在白名单允许范围
+```
+
+或者:
+
+```javascript
+options = {
+ // 白名单,可选
+ whiteList: {
+ a: true, // true表示允许
+ b: /^fixed|relative$/, // 正则test()返回true表示允许
+ c: function (value) {
+ // 返回true表示允许
+ },
+ d: false // 除以上三个以外,所有值均表示不允许
+ },
+ // 当匹配到一个在白名单中的属性时
+ onAttr: function (name, value, options) {
+ // name为属性名
+ // value为属性值
+ // 返回字符串表示覆盖此段CSS
+ // 不返回任何值表示使用默认生成方法,即 name:value
+ },
+ // 当匹配到一个不在白名单中的属性时
+ onIgnoreAttr: function (name, value, options) {
+ // name为属性名
+ // value为属性值
+ // 返回字符串表示覆盖此段CSS
+ // 不返回任何值表示使用默认生成方法,即将此段CSS去掉
+ }
+};
+mycss = new cssfilter.FilterCSS(options);
+// then apply mycss.process()
+css = mycss.process('position:fixed; width:100px; height:100px; background:#aaa;');
+console.log(css);

+For test code please refer to `benchmark` directory.
+
+## They are using xss module
+
+* **nodeclub** - A Node.js bbs using MongoDB - https://github.com/cnodejs/nodeclub
+* **cnpmjs.org** - Private npm registry and web for Enterprise - https://github.com/cnpm/cnpmjs.org
+
+## Install
+
+### NPM
+
+```bash
+npm install xss
+```
+
+### Bower
+
+```bash
+bower install xss
+```
+
+Or
+
+```bash
+bower install https://github.com/leizongmin/js-xss.git
+```
+
+## Usages
+
+### On Node.js
+
+```javascript
+var xss = require("xss");
+var html = xss('<script>alert("xss");</script>');
+console.log(html);
+```
+
+### On Browser
+
+Shim mode (reference file `test/test.html`):
+
+```html
+<script src="https://rawgit.com/leizongmin/js-xss/master/dist/xss.js"></script>
+<script>
+// apply function filterXSS in the same way
+var html = filterXSS('<script>alert("xss");</scr' + 'ipt>');
+alert(html);
+</script>
+```
+
+AMD mode - shim:
+
+```html
+<script>
+require.config({
+ baseUrl: './',
+ paths: {
+ xss: 'https://rawgit.com/leizongmin/js-xss/master/dist/xss.js'
+ },
+ shim: {
+ xss: {exports: 'filterXSS'}
+ }
+})
+require(['xss'], function (xss) {
+ var html = xss('<script>alert("xss");</scr' + 'ipt>');
+ alert(html);
+});
+</script>
+```
+
+**Notes: please don't use the URL https://rawgit.com/leizongmin/js-xss/master/dist/xss.js in production environment.**
+
+## Command Line Tool
+
+### Process File
+
+You can use the xss command line tool to process a file. Usage:
+
+```bash
+xss -i <input_file> -o <output_file>
+```
+
+Example:
+
+```bash
+xss -i origin.html -o target.html
+```
+
+### Active Test
+
+Run the following command, them you can type HTML
+code in the command-line, and check the filtered output:
+
+```bash
+xss -t
+```
+
+For more details, please run `$ xss -h` to see it.
+
+## Custom filter rules
+
+When using the `xss()` function, the second parameter could be used to specify
+custom rules:
+
+```javascript
+options = {}; // Custom rules
+html = xss('<script>alert("xss");</script>', options);
+```
+
+To avoid passing `options` every time, you can also do it in a faster way by
+creating a `FilterXSS` instance:
+
+```javascript
+options = {}; // Custom rules
+myxss = new xss.FilterXSS(options);
+// then apply myxss.process()
+html = myxss.process('<script>alert("xss");</script>');
+```
+
+Details of parameters in `options` would be described below.
+
+### Whitelist
+
+By specifying a `whiteList`, e.g. `{ 'tagName': [ 'attr-1', 'attr-2' ] }`. Tags
+and attributes not in the whitelist would be filter out. For example:
+
+```javascript
+// only tag a and its attributes href, title, target are allowed
+var options = {
+ whiteList: {
+ a: ["href", "title", "target"]
+ }
+};
+// With the configuration specified above, the following HTML:
+// <a href="#" onclick="hello()"><i>Hello</i></a>
+// would become:
+// <a href="#">Hello</a>
+```
+
+For the default whitelist, please refer `xss.whiteList`.
+
+### Customize the handler function for matched tags
+
+By specifying the handler function with `onTag`:
+
+```javascript
+function onTag(tag, html, options) {
+ // tag is the name of current tag, e.g. 'a' for tag <a>
+ // html is the HTML of this tag, e.g. '<a>' for tag <a>
+ // options is some addition informations:
+ // isWhite boolean, whether the tag is in whitelist
+ // isClosing boolean, whether the tag is a closing tag, e.g. true for </a>
+ // position integer, the position of the tag in output result
+ // sourcePosition integer, the position of the tag in input HTML source
+ // If a string is returned, the current tag would be replaced with the string
+ // If return nothing, the default measure would be taken:
+ // If in whitelist: filter attributes using onTagAttr, as described below
+ // If not in whitelist: handle by onIgnoreTag, as described below
+}
+```
+
+### Customize the handler function for attributes of matched tags
+
+By specifying the handler function with `onTagAttr`:
+
+```javascript
+function onTagAttr(tag, name, value, isWhiteAttr) {
+ // tag is the name of current tag, e.g. 'a' for tag <a>
+ // name is the name of current attribute, e.g. 'href' for href="#"
+ // isWhiteAttr whether the attribute is in whitelist
+ // If a string is returned, the attribute would be replaced with the string
+ // If return nothing, the default measure would be taken:
+ // If in whitelist: filter the value using safeAttrValue as described below
+ // If not in whitelist: handle by onIgnoreTagAttr, as described below
+}
+```
+
+### Customize the handler function for tags not in the whitelist
+
+By specifying the handler function with `onIgnoreTag`:
+
+```javascript
+function onIgnoreTag(tag, html, options) {
+ // Parameters are the same with onTag
+ // If a string is returned, the tag would be replaced with the string
+ // If return nothing, the default measure would be taken (specifies using
+ // escape, as described below)
+}
+```
+
+### Customize the handler function for attributes not in the whitelist
+
+By specifying the handler function with `onIgnoreTagAttr`:
+
+```javascript
+function onIgnoreTagAttr(tag, name, value, isWhiteAttr) {
+ // Parameters are the same with onTagAttr
+ // If a string is returned, the value would be replaced with this string
+ // If return nothing, then keep default (remove the attribute)
+}
+```
+
+### Customize escaping function for HTML
+
+By specifying the handler function with `escapeHtml`. Following is the default
+function **(Modification is not recommended)**:
+
+```javascript
+function escapeHtml(html) {
+ return html.replace(/</g, "&lt;").replace(/>/g, "&gt;");
+}
+```
+
+### Customize escaping function for value of attributes
+
+By specifying the handler function with `safeAttrValue`:
+
+```javascript
+function safeAttrValue(tag, name, value) {
+ // Parameters are the same with onTagAttr (without options)
+ // Return the value as a string
+}
+```
+
+### Customize CSS filter
+
+If you allow the attribute `style`, the value will be processed by [cssfilter](https://github.com/leizongmin/js-css-filter) module. The cssfilter module includes a default css whitelist. You can specify the options for cssfilter module like this:
+
+```javascript
+myxss = new xss.FilterXSS({
+ css: {
+ whiteList: {
+ position: /^fixed|relative$/,
+ top: true,
+ left: true
+ }
+ }
+});
+html = myxss.process('<script>alert("xss");</script>');
+```
+
+If you don't want to filter out the `style` content, just specify `false` to the `css` option:
+
+```javascript
+myxss = new xss.FilterXSS({
+ css: false
+});
+```
+
+For more help, please see https://github.com/leizongmin/js-css-filter
+
+### Quick Start
+
+#### Filter out tags not in the whitelist
+
+By using `stripIgnoreTag` parameter:
+
+* `true` filter out tags not in the whitelist
+* `false`: by default: escape the tag using configured `escape` function
+
+Example:
+
+If `stripIgnoreTag = true` is set, the following code:
+
+```html
+code:<script>alert(/xss/);</script>
+```
+
+would output filtered:
+
+```html
+code:alert(/xss/);
+```
+
+#### Filter out tags and tag bodies not in the whitelist
+
+By using `stripIgnoreTagBody` parameter:
+
+* `false|null|undefined` by default: do nothing
+* `'*'|true`: filter out all tags not in the whitelist
+* `['tag1', 'tag2']`: filter out only specified tags not in the whitelist
+
+Example:
+
+If `stripIgnoreTagBody = ['script']` is set, the following code:
+
+```html
+code:<script>alert(/xss/);</script>
+```
+
+would output filtered:
+
+```html
+code:
+```
+
+#### Filter out HTML comments
+
+By using `allowCommentTag` parameter:
+
+* `true`: do nothing
+* `false` by default: filter out HTML comments
+
+Example:
+
+If `allowCommentTag = false` is set, the following code:
+
+```html
+code:<!-- something --> END
+```
+
+would output filtered:
+
+```html
+code: END
+```
+
+## Examples
+
+### Allow attributes of whitelist tags start with `data-`
+
+```javascript
+var source = '<div a="1" b="2" data-a="3" data-b="4">hello</div>';
+var html = xss(source, {
+ onIgnoreTagAttr: function(tag, name, value, isWhiteAttr) {
+ if (name.substr(0, 5) === "data-") {
+ // escape its value using built-in escapeAttrValue function
+ return name + '="' + xss.escapeAttrValue(value) + '"';
+ }
+ }
+});
+
+console.log("%s\nconvert to:\n%s", source, html);
+```
+
+Result:
+
+```html
+<div a="1" b="2" data-a="3" data-b="4">hello</div>
+convert to:
+<div data-a="3" data-b="4">hello</div>
+```
+
+### Allow tags start with `x-`
+
+```javascript
+var source = "<x><x-1>he<x-2 checked></x-2>wwww</x-1><a>";
+var html = xss(source, {
+ onIgnoreTag: function(tag, html, options) {
+ if (tag.substr(0, 2) === "x-") {
+ // do not filter its attributes
+ return html;
+ }
+ }
+});
+
+console.log("%s\nconvert to:\n%s", source, html);
+```
+
+Result:
+
+```html
+<x><x-1>he<x-2 checked></x-2>wwww</x-1><a>
+convert to:
+&lt;x&gt;<x-1>he<x-2 checked></x-2>wwww</x-1><a>
+```
+
+### Parse images in HTML
+
+```javascript
+var source =
+ '<img src="img1">a<img src="img2">b<img src="img3">c<img src="img4">d';
+var list = [];
+var html = xss(source, {
+ onTagAttr: function(tag, name, value, isWhiteAttr) {
+ if (tag === "img" && name === "src") {
+ // Use the built-in friendlyAttrValue function to escape attribute
+ // values. It supports converting entity tags such as &lt; to printable
+ // characters such as <
+ list.push(xss.friendlyAttrValue(value));
+ }
+ // Return nothing, means keep the default handling measure
+ }
+});
+
+console.log("image list:\n%s", list.join(", "));
+```
+
+Result:
+
+```html
+image list:
+img1, img2, img3, img4
+```
+
+### Filter out HTML tags (keeps only plain text)
+
+```javascript
+var source = "<strong>hello</strong><script>alert(/xss/);</script>end";
+var html = xss(source, {
+ whiteList: [], // empty, means filter out all tags
+ stripIgnoreTag: true, // filter out all HTML not in the whilelist
+ stripIgnoreTagBody: ["script"] // the script tag is a special case, we need
+ // to filter out its content
+});
+
+console.log("text: %s", html);
+```
+
+Result:
+
+```html
+text: helloend
+```

+# 根据白名单过滤 HTML(防止 XSS 攻击)
+
+![xss](https://nodei.co/npm/xss.png?downloads=true&stars=true)
+
+---
+
+`xss`是一个用于对用户输入的内容进行过滤,以避免遭受 XSS 攻击的模块([什么是 XSS 攻击?](http://baike.baidu.com/view/2161269.htm))。主要用于论坛、博客、网上商店等等一些可允许用户录入页面排版、格式控制相关的 HTML 的场景,`xss`模块通过白名单来控制允许的标签及相关的标签属性,另外还提供了一系列的接口以便用户扩展,比其他同类模块更为灵活。
+
+**项目主页:** http://jsxss.com
+
+**在线测试:** http://jsxss.com/zh/try.html
+
+---
+
+## 特性
+
+* 白名单控制允许的 HTML 标签及各标签的属性
+* 通过自定义处理函数,可对任意标签及其属性进行处理
+

+
+## 性能(仅作参考)
+
+* xss 模块:8.2 MB/s
+* validator@0.3.7 模块的 xss()函数:4.4 MB/s
+
+测试代码参考 benchmark 目录
+
+## 安装
+
+### NPM
+
+```bash
+npm install xss
+```
+
+### Bower
+
+```bash
+bower install xss
+```
+
+或者
+
+```bash
+bower install https://github.com/leizongmin/js-xss.git
+```
+
+## 使用方法
+
+### 在 Node.js 中使用
+
+```javascript
+var xss = require("xss");
+var html = xss('<script>alert("xss");</script>');
+console.log(html);
+```
+
+### 在浏览器端使用
+
+Shim 模式(参考文件 `test/test.html`):
+
+```html
+<script src="https://rawgit.com/leizongmin/js-xss/master/dist/xss.js"></script>
+<script>
+// 使用函数名 filterXSS,用法一样
+var html = filterXSS('<script>alert("xss");</scr' + 'ipt>');
+alert(html);
+</script>
+```
+
+AMD 模式(参考文件 `test/test_amd.html`):
+
+```html
+<script>
+require.config({
+ baseUrl: './',
+ paths: {
+ xss: 'https://rawgit.com/leizongmin/js-xss/master/dist/xss.js'
+ },
+ shim: {
+ xss: {exports: 'filterXSS'}
+ }
+})
+require(['xss'], function (xss) {
+ var html = xss('<script>alert("xss");</scr' + 'ipt>');
+ alert(html);
+});
+</script>
+```
+
+**说明:请勿将 URL https://rawgit.com/leizongmin/js-xss/master/dist/xss.js 用于生产环境。**
+
+### 使用命令行工具来对文件进行 XSS 处理
+
+### 处理文件
+
+可通过内置的 `xss` 命令来对输入的文件进行 XSS 处理。使用方法:
+
+```bash
+xss -i <源文件> -o <目标文件>
+```
+
+例:
+
+```bash
+xss -i origin.html -o target.html
+```
+
+### 在线测试
+
+执行以下命令,可在命令行中输入 HTML 代码,并看到过滤后的代码:
+
+```bash
+xss -t
+```
+
+详细命令行参数说明,请输入 `$ xss -h` 来查看。
+
+## 自定义过滤规则
+
+在调用 `xss()` 函数进行过滤时,可通过第二个参数来设置自定义规则:
+
+```javascript
+options = {}; // 自定义规则
+html = xss('<script>alert("xss");</script>', options);
+```
+
+如果不想每次都传入一个 `options` 参数,可以创建一个 `FilterXSS` 实例(使用这种方法速度更快):
+
+```
+options = {}; // 自定义规则
+myxss = new xss.FilterXSS(options);
+// 以后直接调用 myxss.process() 来处理即可
+html = myxss.process('<script>alert("xss");</script>');
+```
+
+`options` 参数的详细说明见下文。
+
+### 白名单
+
+通过 `whiteList` 来指定,格式为:`{'标签名': ['属性1', '属性2']}`。不在白名单上的标签将被过滤,不在白名单上的属性也会被过滤。以下是示例:
+
+```javascript
+// 只允许a标签,该标签只允许href, title, target这三个属性
+var options = {
+ whiteList: {
+ a: ["href", "title", "target"]
+ }
+};
+// 使用以上配置后,下面的HTML
+// <a href="#" onclick="hello()"><i>大家好</i></a>
+// 将被过滤为
+// <a href="#">大家好</a>
+```
+
+默认白名单参考 `xss.whiteList`。
+
+### 自定义匹配到标签时的处理方法
+
+通过 `onTag` 来指定相应的处理函数。以下是详细说明:
+
+```javascript
+function onTag(tag, html, options) {
+ // tag是当前的标签名称,比如<a>标签,则tag的值是'a'
+ // html是该标签的HTML,比如<a>标签,则html的值是'<a>'
+ // options是一些附加的信息,具体如下:
+ // isWhite boolean类型,表示该标签是否在白名单上
+ // isClosing boolean类型,表示该标签是否为闭合标签,比如</a>时为true
+ // position integer类型,表示当前标签在输出的结果中的起始位置
+ // sourcePosition integer类型,表示当前标签在原HTML中的起始位置
+ // 如果返回一个字符串,则当前标签将被替换为该字符串
+ // 如果不返回任何值,则使用默认的处理方法:
+ // 在白名单上: 通过onTagAttr来过滤属性,详见下文
+ // 不在白名单上:通过onIgnoreTag指定,详见下文
+}
+```
+
+### 自定义匹配到标签的属性时的处理方法
+
+通过 `onTagAttr` 来指定相应的处理函数。以下是详细说明:
+
+```javascript
+function onTagAttr(tag, name, value, isWhiteAttr) {
+ // tag是当前的标签名称,比如<a>标签,则tag的值是'a'
+ // name是当前属性的名称,比如href="#",则name的值是'href'
+ // value是当前属性的值,比如href="#",则value的值是'#'
+ // isWhiteAttr是否为白名单上的属性
+ // 如果返回一个字符串,则当前属性值将被替换为该字符串
+ // 如果不返回任何值,则使用默认的处理方法
+ // 在白名单上: 调用safeAttrValue来过滤属性值,并输出该属性,详见下文
+ // 不在白名单上:通过onIgnoreTagAttr指定,详见下文
+}
+```
+
+### 自定义匹配到不在白名单上的标签时的处理方法
+
+通过 `onIgnoreTag` 来指定相应的处理函数。以下是详细说明:
+
+```javascript
+function onIgnoreTag(tag, html, options) {
+ // 参数说明与onTag相同
+ // 如果返回一个字符串,则当前标签将被替换为该字符串
+ // 如果不返回任何值,则使用默认的处理方法(通过escape指定,详见下文)
+}
+```
+
+### 自定义匹配到不在白名单上的属性时的处理方法
+
+通过 `onIgnoreTagAttr` 来指定相应的处理函数。以下是详细说明:
+
+```javascript
+function onIgnoreTagAttr(tag, name, value, isWhiteAttr) {
+ // 参数说明与onTagAttr相同
+ // 如果返回一个字符串,则当前属性值将被替换为该字符串
+ // 如果不返回任何值,则使用默认的处理方法(删除该属)
+}
+```
+
+### 自定义 HTML 转义函数
+
+通过 `escapeHtml` 来指定相应的处理函数。以下是默认代码 **(不建议修改)** :
+
+```javascript
+function escapeHtml(html) {
+ return html.replace(/</g, "&lt;").replace(/>/g, "&gt;");
+}
+```
+
+### 自定义标签属性值的转义函数
+
+通过 `safeAttrValue` 来指定相应的处理函数。以下是详细说明:
+
+```javascript
+function safeAttrValue(tag, name, value) {
+ // 参数说明与onTagAttr相同(没有options参数)
+ // 返回一个字符串表示该属性值
+}
+```
+
+### 自定义 CSS 过滤器
+
+如果配置中允许了标签的 `style` 属性,则它的值会通过[cssfilter](https://github.com/leizongmin/js-css-filter) 模块处理。
+`cssfilter` 模块包含了一个默认的 CSS 白名单,你可以通过以下的方式配置:
+
+```javascript
+myxss = new xss.FilterXSS({
+ css: {
+ whiteList: {
+ position: /^fixed|relative$/,
+ top: true,
+ left: true
+ }
+ }
+});
+html = myxss.process('<script>alert("xss");</script>');
+```
+
+如果不想使用 CSS 过滤器来处理 `style` 属性的内容,可指定 `css` 选项的值为 `false`:
+
+```javascript
+myxss = new xss.FilterXSS({
+ css: false
+});
+```
+
+要获取更多的帮助信息可看这里:https://github.com/leizongmin/js-css-filter
+
+### 快捷配置
+
+#### 去掉不在白名单上的标签
+
+通过 `stripIgnoreTag` 来设置:
+
+* `true`:去掉不在白名单上的标签
+* `false`:(默认),使用配置的`escape`函数对该标签进行转义
+
+示例:
+
+当设置 `stripIgnoreTag = true`时,以下代码
+
+```html
+code:<script>alert(/xss/);</script>
+```
+
+过滤后将输出
+
+```html
+code:alert(/xss/);
+```
+
+#### 去掉不在白名单上的标签及标签体
+
+通过 `stripIgnoreTagBody` 来设置:
+
+* `false|null|undefined`:(默认),不特殊处理
+* `'*'|true`:去掉所有不在白名单上的标签
+* `['tag1', 'tag2']`:仅去掉指定的不在白名单上的标签
+
+示例:
+
+当设置 `stripIgnoreTagBody = ['script']`时,以下代码
+
+```html
+code:<script>alert(/xss/);</script>
+```
+
+过滤后将输出
+
+```html
+code:
+```
+
+#### 去掉 HTML 备注
+
+通过 `allowCommentTag` 来设置:
+
+* `true`:不处理
+* `false`:(默认),自动去掉 HTML 中的备注
+
+示例:
+
+当设置 `allowCommentTag = false` 时,以下代码
+
+```html
+code:<!-- something --> END
+```
+
+过滤后将输出
+
+```html
+code: END
+```
+
+## 应用实例
+
+### 允许标签以 data-开头的属性
+
+```javascript
+var source = '<div a="1" b="2" data-a="3" data-b="4">hello</div>';
+var html = xss(source, {
+ onIgnoreTagAttr: function(tag, name, value, isWhiteAttr) {
+ if (name.substr(0, 5) === "data-") {
+ // 通过内置的escapeAttrValue函数来对属性值进行转义
+ return name + '="' + xss.escapeAttrValue(value) + '"';
+ }
+ }
+});
+
+console.log("%s\nconvert to:\n%s", source, html);
+```
+
+运行结果:
+
+```html
+<div a="1" b="2" data-a="3" data-b="4">hello</div>
+convert to:
+<div data-a="3" data-b="4">hello</div>
+```
+
+### 允许名称以 x-开头的标签
+
+```javascript
+var source = "<x><x-1>he<x-2 checked></x-2>wwww</x-1><a>";
+var html = xss(source, {
+ onIgnoreTag: function(tag, html, options) {
+ if (tag.substr(0, 2) === "x-") {
+ // 不对其属性列表进行过滤
+ return html;
+ }
+ }
+});
+
+console.log("%s\nconvert to:\n%s", source, html);
+```
+
+运行结果:
+
+```html
+<x><x-1>he<x-2 checked></x-2>wwww</x-1><a>
+convert to:
+&lt;x&gt;<x-1>he<x-2 checked></x-2>wwww</x-1><a>
+```
+
+### 分析 HTML 代码中的图片列表
+
+```javascript
+var source =
+ '<img src="img1">a<img src="img2">b<img src="img3">c<img src="img4">d';
+var list = [];
+var html = xss(source, {
+ onTagAttr: function(tag, name, value, isWhiteAttr) {
+ if (tag === "img" && name === "src") {
+ // 使用内置的friendlyAttrValue函数来对属性值进行转义,可将&lt;这类的实体标记转换成打印字符<
+ list.push(xss.friendlyAttrValue(value));
+ }
+ // 不返回任何值,表示还是按照默认的方法处理
+ }
+});
+
+console.log("image list:\n%s", list.join(", "));
+```
+
+运行结果:
+
+```html
+image list:
+img1, img2, img3, img4
+```
+
+### 去除 HTML 标签(只保留文本内容)
+
+```javascript
+var source = "<strong>hello</strong><script>alert(/xss/);</script>end";
+var html = xss(source, {
+ whiteList: [], // 白名单为空,表示过滤所有标签
+ stripIgnoreTag: true, // 过滤所有非白名单标签的HTML
+ stripIgnoreTagBody: ["script"] // script标签较特殊,需要过滤标签中间的内容
+});
+
+console.log("text: %s", html);
+```
+
+运行结果:
+
+```html
+text: helloend
+```
