Find definitions
Find definitions – searching for selectors and properties
One of features of HTML_CSS that was still missing to version less or equal than 1.0.1 is ability to detect if a selector (or group of selectors), and/or a property (or group of properties) was already defined. This is now possible with method : HTML_CSS::grepStyle()
Searching for a group of selectors
Let creates these definitions into progress2.css file :
#PB1.cellPB1I, #PB1.cellPB1A { width: 15px; height: 20px; font-family: Courier, Verdana; font-size: 8px; float: left; } #PB1.progressBorderPB1 { width: 172px; height: 24px; border-width: 1px; border-style: solid; border-color: #404040 #dfdfdf #dfdfdf #404040; background-color: #CCCCCC; } .progressPercentLabelpct1PB1 { width: 50px; text-align: right; background-color: transparent; font-size: 11px; font-family: Verdana, Tahoma, Arial; font-weight: normal; color: #000000; } .progressTextLabeltxt1PB1 { text-align: left; background-color: transparent; font-size: 11px; font-family: Verdana, Tahoma, Arial; font-weight: normal; color: #000000; } .cellPB1I { background-color: #CCCCCC; } .cellPB1A { background-color: #0033FF; } body { background-color: #E0E0E0; color: #000000; font-family: Verdana, Arial; }
Very easy with such script to find where is declared #PB1 class selectors (names like).
<?php
require_once 'HTML/CSS.php';
$css = new HTML_CSS();
$css->parseFile('progress2.css');
// find all selectors beginning with #PB1
$styles = $css->grepStyle('/^#PB1/');
echo '<pre>'; var_dump($styles); echo '</pre>';
?>
Searching for selectors that set a property
We still used the CSS definitions of previous example, identified by progress2.css file :
Very easy with such script to find where is declared color property.
<?php
require_once 'HTML/CSS.php';
$css = new HTML_CSS();
$css->parseFile('progress2.css');
// find all selectors that set the color property
$styles = $css->grepStyle('/./', '/^color$/');
echo '<pre>'; var_dump($styles); echo '</pre>';
?>
