|

* removes HTML comments and expands templates
|
||
* - Parser::cleanSig() and Parser::cleanSigInSig()
|
||
* Cleans a signature before saving it to preferences
|
||
* - Parser::getSection()
|
||
* Return the content of a section from an article for section editing
|
||
* - Parser::replaceSection()
|
