note 67205 rejected from function.dom-domdocument-getelementbyid by didou

Note Submitter: richard at 2006 dot atterer dot net ---- OK, so maybe PHP's getElementById() is behaving according to spec, but it does not have the behaviour that people *want*... Below is a global getElementById() function (i.e. not a DOMDocument method) which recursively searches through a document for a certain id value. /* Find the first element in the document (sub)tree whose id attribute has the value $id. By default, the entire document is searched - pass a non-NULL value in $node to search only the subtree below $node. */ function getElementById(DOMDocument $doc, /*string*/ $id, DOMNode $node = NULL) { if ($node === NULL) return getElementById($doc, $id, $doc->documentElement); $children = $node->childNodes; for ($i = 0; $i < $children->length; ++$i) { $elem = $children->item($i); if (!($elem instanceof DOMElement)) continue; if ($elem->getAttribute('id') == $id) return $elem; $ret = getElementById($doc, $id, $elem); if ($ret !== NULL) return $ret; } return NULL; }
