*
|
||||
* 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.
