PHP DOMDocument: How to get direct node childrens
I've got the following:
http://pastie.org/1066861
I've got a Javascript function, that tells me to delete a given node from the parent, let's assume position 1 ( from 0 or 1, since we've got two child nodes on parent ), When doing $parent->getElementsByTagName and trying to remove the the $child->item( 1 ), I notice that PHP GetElementsByTagName is giving me a diferent position, 开发者_如何学Pythonfor that specific node. So, there's no way to access the right node, that JS told.
I guess I should stay away of getElementsByTagName, and use getElementsById, but right now I would like to learn and understand why this doesnt work properly.
Here's some code: http://pastie.org/1066857
Thanks a lot for your atention ;D
Found a solution,
/*
* deleteNode() removes given node, in position X.
*/
function deleteNode( $html, $strParent, $intNodePosition ) {
$domhtml = DOMDocument::loadHTML($html);
$xpath = new DOMXPath($domhtml);
$divs = $xpath->query( "*/div[@id='maindiv']/div" );
$node = $divs->item( $intNodePosition );
$node->parentNode->removeChild( $node );
/*
this wont work, but why ? It should
$divs->removeChild( $node );
*/
return $domhtml->saveHTML();
}//fim deleteNode
