Could someone explain to me what I'm doing wrong?
I'm trying to get an element from one DOMDocument and append it to a
different DOMDocument. The (simplified) output of saveXML() from the
first DOMDocument is as follows:
<?xml version="1.0" encoding="UTF-8"?> <BranchRoot
id="root"><option>1</option><option>2</option></BranchRoot>
Here is a snippet of code:
<?php
$oXmlDocument = new DOMDocument( '1.0', 'UTF-8' );
$oRootNode = $oXmlDocument->createElement( 'menu' );
$oRootNode->setAttribute( 'id', 'root' );
$oRootNode->setIdAttribute( 'id', TRUE );
$oRootNode->setAttribute( 'style', $sStyle );
$oRootNode->setAttribute( 'width', $iWidth );
$oRootNode->setAttribute( 'target', $sTarget );
$oRootNode->setAttribute( 'indent', $iIndent );
$oXmlDocument->appendChild( $oRootNode );
$oNewChildEl = $oFirstDoc->getElementById( 'root' );
$oRootNode->appendChild( $oNewChildEl );
?>
I'm printing out what $oNewChildEl is to see if it's not returning the
proper element, using
echo '[' . $oNewChildEl->tagName . ']' . var_dump( $oNewChildEl );
and I'm seeing:
object(DOMElement)#1055 (0) { } [BranchRoot]
so it does look like it's returning the proper DOMElement. But even
so, I'm getting a fatal error when $oRootNode is trying to
appendChild(). Specifically, the error I'm getting is
Fatal error: Uncaught exception 'DOMException' with message 'Wrong
Document Error'
What's going on? It doesn't seem like I'm doing anything wrong but
something is causing the problem and I apparently do not understand
exactly what.
Could anyone lend any insight as to what's going on? And what I might
do to get what I need done?
thnx,
Chris
