If you do not provide the second argument, the context node, then by default the context node of the query is the root element node, not the document node. Thus if you have <?php $xmlSource = <<<XMLEND <!-- top level comment --> <?processing-instruction arg="value"?> <root> <child>Kibology</child> <child>PHP</child> </root> XMLEND; $xmlDocument = new DOMDocument(); $xmlDocument->loadXML($xmlSource); $xPathEvaluator = new DOMXPath($xmlDocument); ?> then the following <?php $nodeList = $xPathEvaluator->query('self::node()'); echo 'nodeType: ' . $nodeList->item(0)->nodeType . '; nodeName: ' . $nodeList->item(0)->nodeName ."<br>\r\n"; // nodeType is 1 ?> yields nodeType: 1; nodeName: root while <?php $nodeList = $xPathEvaluator->query('self::node()', $xmlDocument); echo 'nodeType: ' . $nodeList->item(0)->nodeType . '; nodeName: ' . $nodeList->item(0)->nodeName ."<br>\r\n"; // nodeType is 9 ?> yields nodeType: 9; nodeName: #document ---- Manual Page -- http://www.php.net/manual/en/function.dom-domxpath-query.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+48040 Delete -- http://master.php.net/manage/user-notes.php?action=delete+48040&report=yes Reason: bad code -- http://master.php.net/manage/user-notes.php?action=delete+48040&report=yes&reason=bad+code Reason: spam -- http://master.php.net/manage/user-notes.php?action=delete+48040&report=yes&reason=spam Reason: useless example -- http://master.php.net/manage/user-notes.php?action=delete+48040&report=yes&reason=useless+example Reason: contains commercial links -- http://master.php.net/manage/user-notes.php?action=delete+48040&report=yes&reason=contains+commercial+links Reason: useless note -- http://master.php.net/manage/user-notes.php?action=delete+48040&report=yes&reason=useless+note Reject -- http://master.php.net/manage/user-notes.php?action=reject+48040&report=yes Search -- http://master.php.net/manage/user-notes.php
