Class Overview

Parser

   --CSS_Parser

Parses CSS data into 3-dimensional associative arrays. Properly handles multiple declaration blocks for the same element, but will only keep the final value of a property that is declared again, which should not be a problem for most cases. Also properly handles /* style comments.

Parses CSS data into 3-dimensional associative arrays. Properly handles multiple declaration blocks for the same element, but will only keep the final value of a property that is declared again, which should not be a problem for most cases. Also properly handles /* style comments.

Example:


1     <?php
2     
3      loader_import ('saf.HTML.CSS_Parser');
4     
5      $css = new CSS_Parser ();
6     
7      $css->parse ('a { text-decoration: none } div.content { line-height: 15px }');
8     
9      info ($css->list['a']);
10    
11     info ($css->getClasses ('div'));
