Adding Attributes to all XML nodes

[empiresolutions]

Howdy,

I have an PHP page that edits XML files. I want ADD a new *id* attribute to all nodes on the page that do not have it all ready. Then i want to delete all of the values of *id* and set them as an incremental 1-x values down the page.

This is the current code i am using to edit specific nodes.
[code=php]
<?php
$content = $_POST['content'];
$id = $_POST['id'];
$node = $_POST['node'];
$explode = explode("_",$no de);

$dom=new DOMDocument();
$dom->load('sample.x ml');
$dom->formatOutput = true;
//echo $dom->saveXML(); // show before file
$allnodes = $dom->getElementsByT agName($explode[0]);
foreach ($allnodes as $nodes) {
if ($nodes->nodeName==$exp lode[0] and $nodes->getAttribute(' id')==$id) { //
$nodes->setAttribute($ explode[1],$content);
}
}
$dom->save('sample.x ml');
?>
[/code]

This is the XML file im working with. NOTE the missing *id* node of the 2nd *child01* node.
[code=xml]
