|

* @description
|
||||
* The input is sanitized by parsing the HTML into tokens. All safe tokens (from a whitelist) are
|
||||
* then serialized back to properly escaped html string. This means that no unsafe input can make
|
||||
* it into the returned string, however, since our parser is more strict than a typical browser
|
||||
* parser, it's possible that some obscure input, which would be recognized as valid HTML by a
|
||||
* browser, won't make it through the sanitizer. The input may also contain SVG markup.
|
||||
* The whitelist is configured using the functions `aHrefSanitizationWhitelist` and
|
||||
* `imgSrcSanitizationWhitelist` of {@link ng.$compileProvider `$compileProvider`}.
|
||||
*
|
||||
* @param {string} html HTML input.
|
||||
* @returns {string} Sanitized HTML.
