Sanitize your HTML the easy way!

install

test

vows --spec test/*

example

Basic:
````javascript
var bleach = require('bleach');
var html = bleach.sanitize(aBunchOfHTML);
console.log(html); ````
Advanced:
````javascript
var bleach = require('bleach');
var whitelist = 'a', 'b', 'i', 'em', 'strong'
var options = { mode: 'white', list: whitelist }
var html = bleach.sanitize(aBunchOfHTML, options);
console.log(html); ````

usage

bleach.sanitize(html, options)

Runs HTML through sanitizer and returns sanitized HTML as string.
options may contain the following optional attributes:

• mode may be set to 'white' or 'black'
• list is an array containing tags to match against

whitemode will remove all tags from html, excluding those in list
blackmode will remove all tags found in list that are found in html

bleach.analyze(html)

Will extract all tags from HTML and return an array of JSON objects. Example return:
````javascript {

full: '<div id="post-119477">',
name: 'div',
attr: [
  "id": "post-119477"
]

}, ... ````

bleach.filter(html, filters)

SEXY FUN TIME
````javascript
var nyanFilter = function(input){ return input.replace('cats', 'nyannyannyan'); }
console.log( bleach.filter('cats', nyanFilter) );
// nyannyannyan
````
````javascript
var cutFilter = function(input){ return input.slice(0, 3); }
console.log( bleach.filter('cats',

nyanFilter,
cutFilter

) );
// nyan
````
You may also define longer filters and include them in the ./nodemodules/bleach/filters directory. A sample filter is included to convert YouTube flash embed objects to iDevice-compatible YouTube iframes.
````javascript
var html = '';
console.log( bleach.filter(html, 'youtube') );
//
````
Refer to the filters directory for the template.

disclaimer

This is not a port of the Python bleach library - in fact their implementations are very different.
