|

|
* 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 whitelist is configured using the functions `aHrefSanitizationWhitelist` and
|
||||||
|
* `imgSrcSanitizationWhitelist` of {@link ng.$compileProvider `$compileProvider`}.
|
||||||
|
*
|
