* HTML Purifier is an HTML filter that will take an arbitrary snippet of

* HTML and rigorously test, validate and filter it into a version that
|
||||
* is safe for output onto webpages. It achieves this by:
|
||||
*
|
||||
* -# Lexing (parsing into tokens) the document,
|
||||
* -# Executing various strategies on the tokens:
|
||||
* -# Removing all elements not in the whitelist,
|
||||
* -# Making the tokens well-formed,
|
||||
* -# Fixing the nesting of the nodes, and
|
||||
* -# Validating attributes of the nodes; and
|
||||
* -# Generating HTML from the purified tokens.
|
||||
*
|
||||
* However, most users will only need to interface with the HTMLPurifier
|
||||
* and HTMLPurifier_Config.

|

// names.
|

// most parsers give little thought to Unicode, treatment
|
||||
// of these codepoints is basically uniform, even for
|
||||
// punctuation-like codepoints. These characters can

|

// legitimate font-name
|

// <http://ja.wikipedia.org/wiki/MS_明朝>. See
|
||||
// the CSS3 spec for more examples:
|
||||
// <http://www.w3.org/TR/2011/WD-css3-fonts-20110324/localizedfamilynames.png>
|
||||
// You can see live samples of these on the Internet:
|
||||
// <http://www.google.co.jp/search?q=font-family+ＭＳ+明朝|ゴシック>
|
||||
// However, most of these fonts have ASCII equivalents:
|
||||
// for example, 'MS Mincho', and it's considered
|
||||
// professional to use ASCII font names instead of
|
||||
// Unicode font names. Thanks Takeshi Terada for
|
||||
// providing this information.
|
||||
// The following characters, to my knowledge, have not been
|
||||
// used to name font names.
|
||||
// - Single quote. While theoretically you might find a
|
||||
// font name that has a single quote in its name (serving
|
||||
// as an apostrophe, e.g. Dave's Scribble), I haven't
|
||||
// been able to find any actual examples of this.
|
||||
// Internet Explorer's cssText translation (which I
|
||||
// believe is invoked by innerHTML) normalizes any
|
||||
// quoting to single quotes, and fails to escape single
|
||||
// quotes. (Note that this is not IE's behavior for all
|
||||
// CSS properties, just some sort of special casing for
|
||||
// font-family). So a single quote *cannot* be used
|
||||
// safely in the font-family context if there will be an
|
||||
// innerHTML/cssText translation. Note that Firefox 3.x
|
||||
// does this too.
|
||||
// - Double quote. In IE, these get normalized to
|
||||
// single-quotes, no matter what the encoding. (Fun
|
||||
// fact, in IE8, the 'content' CSS property gained
|
||||
// support, where they special cased to preserve encoded
|
||||
// double quotes, but still translate unadorned double
|
||||
// quotes into single quotes.) So, because their
|
||||
// fixpoint behavior is identical to single quotes, they
|
||||
// cannot be allowed either. Firefox 3.x displays
|
||||
// single-quote style behavior.
|
||||
// - Backslashes are reduced by one (so \\ -> \) every
|
||||
// iteration, so they cannot be used safely. This shows
|
||||
// up in IE7, IE8 and FF3
|
||||
// - Semicolons, commas and backticks are handled properly.
|
||||
