If the query() function seems to ignore your $contextnode, and instead returns all the tags in the document, try to use a relative path (use a . in front of the query): <?php $xml = "<?xml version='1.0' encoding='UTF-8'?> <test> <tag1> <uselesstag> <tag2>test</tag2> </uselesstag> </tag1> <tag2>test2</tag2> </test>"; $dom = new DomDocument(); $dom->loadXML($xml); $xpath = new DomXPath($dom); $tag1 = $dom->getElementsByTagName("tag1")->item(0); echo $xpath->query("//tag2")->length; //output 2 -> correct echo $xpath->query("//tag2", $tag1)->length; //output 2 -> wrong, the query is not relative echo $xpath->query(".//tag2", $tag1)->length; //output 1 -> correct (note the dot in front of //) ?> See that i couldn't use $xpath->query("tag2", $tag1) as per the documentation, since "tag2" is not a direct child of "tag1". I don't know why this note was deleted, i just tested it and it's correct. It's not a bug, it's simply not written in the documentation. ---- Server IP: 69.147.83.197 Probable Submitter: 85.18.24.54 ---- Manual Page -- http://www.php.net/manual/en/domxpath.query.php Edit -- https://master.php.net/note/edit/99760 Del: integrated -- https://master.php.net/note/delete/99760/integrated Del: useless -- https://master.php.net/note/delete/99760/useless Del: bad code -- https://master.php.net/note/delete/99760/bad+code Del: spam -- https://master.php.net/note/delete/99760/spam Del: non-english -- https://master.php.net/note/delete/99760/non-english Del: in docs -- https://master.php.net/note/delete/99760/in+docs Del: other reasons-- https://master.php.net/note/delete/99760 Reject -- https://master.php.net/note/reject/99760 Search -- https://master.php.net/manage/user-notes.php
