|
* The input is sanitized by parsing the html into tokens. All safe tokens (from a whitelist) are

|
* 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.
