|

* This is a parser to replace UBB style tags with their html equivalents. It
|
||||
* does not simply do some regex calls, but is complete stack based
|
||||
* parse engine. This ensures that all tags are properly nested, if not,
|
||||
* extra tags are added to maintain the nesting. This parser should only produce
|
||||
* xhtml 1.0 compliant code. All tags are validated and so are all their attributes.
|
||||
* It should be easy to extend this parser with your own tags, see the _definedTags
|
||||
* format description below.
|
||||
*
|
||||
*
|
||||
* Usage:
|
||||
* $parser = new SSHTMLBBCodeParser();
|

* $parser->setText('normal [b]bold[/b] and normal again');
|
||||
* $parser->parse();
|
||||
* echo $parser->getParsed();

||||
* or:
|
||||
* $parser = new SSHTMLBBCodeParser();
|
||||
* echo $parser->qparse('normal [b]bold[/b] and normal again');
|
||||
* or:
|
||||
* echo SSHTMLBBCodeParser::staticQparse('normal [b]bold[/b] and normal again');
|
||||
*

|
||||
* $options = &PEAR::getStaticProperty('SSHTMLBBCodeParser', '_options');
