thank you.

use dom load html document , xpath search it.

// note: if html parse has bad syntax, use: libxml_use_internal_errors(true);  $doc = new domdocument; $doc->loadhtml(file_get_contents('a.html')); if ($doc === false) {     throw new runtimeexception('could not load html'); }  $xpath = new domxpath($doc); $xpathresult = $xpath->query("//a[@href = '../collection?file={$_get['file']}']/.."); if ($xpathresult === false) {     throw new logicexception('something went wrong querying document!'); }  foreach ($xpathresult $domnode) {     echo 'link text: ' . htmlentities($domnode->textcontent) . php_eol; }
