Need help with the XML DOM remove_child method

[paragpdoke]

Hello Everyone.

I'm new to PHP and I'm trying to get some XML manipulation working.

Somehow I can't get the remove_child method to work for me. Here are

the details:

 

XML structure:

<?xml version="1.0"?>
<?xml-stylesheet type='text/xsl' href='myXSL.xsl'?>
<ServerList>
<Server id="myServer1">
     <!--Some tags here. These tags have no children-->
     <Tag1>AAA1</Tag1>
     <Tag2>BBB2</Tag2>
     <TagN>ZZZ3</TagN>
</Server>
<Server id="myServer2">
     <!--Some tags here. These tags have no children-->
     <Tag1>AAA4</Tag1>
     <Tag2>BBB5</Tag2>
     <TagN>ZZZ6</TagN>
</Server>
</ServerList>

I'm trying to capture some _REQUEST variables and create a new server

node in the XML DOM. Before this, I query the DOM using xpath and the

server id. If the server is found, I intend to delete that node and

rest of the php code (creation of the new server node) follows

suitably.

 

PHP code excerpt:

$dom=new DOMDocument();
$dom->load("myXML.xml");
$myXpath=new Domxpath($dom);
//$ServerID is populated correctly based on _REQUEST variables.
$myQuery="/ServerList/Server[@id='".$ServerID."']";
$result=$myXpath->query($myQuery);
if (($result->length) == 1) {
//What follows is line # L
$dom->document_element->remove_child($result->item(0));
}
//Some more code...probably irrelevant at this moment.

The error I'm observing is:

Fatal error:  Call to a member function remove_child() on a non-object
in myPHP.php on line L.

 

The page at:

http://www.php.net/manual/en/function.domdocument-document-element.php

has a comment saying "documentElement" should be used in PHP 5 rather

than "document_element". With that change, I'm running into a new

error with PHP 5.2.5.

 

How to use the remove_child method if it belongs to a DOMNode and not

a DOMElement ? Or rather, how to convert output of

DOMDocument->documentElement to type DOMNode so that the remove_child

method is supported ?

 

Thanks in advance,

The DOM methods use camelCase as naming convention.
