php - How can I query my HTML using this jQuery expression? -

i'm processing html , need query particular subset of it, know how jquery selectors.

here's php code:

$words = array('word');         $baseurl = 'http://lema.rae.es/drae/srv/search?val='; //word goes @ end         $resultindex = 0;  foreach($words $word) {     if (!isset($_request[$word]))         continue;     $contents = file_get_contents($baseurl . urldecode(utf8_decode($_request[$word])));      // doesn't work! how write in php     $dataineed = $contents.find(".ul a").attr("href");       $contents = preg_replace('/(search?[\d\w]+)/','http://lema.rae.es/drae/srv/',     $contents);      echo "<div id='results' style='       //style      ", (++$resultindex) ,"'>", $dataineed, $contents,         "</div>"; } 

the query use in jquery this:

.find(".ul a").attr("href") 

how can write using php , dom?

using xpath:

$doc = new domdocument(); $doc->loadhtml($contents); $xp = new domxpath($doc);  $dataineed = $xp->query('//*[contains(concat(" ",@class," ")," ul ")]//a')     ->item(0)     ->getattribute('href');
