PHP DOM

[TheJoey]

<?php
$xmlDoc = new DOMDocument();
$xmlDoc->load("abc.xml");


// We need to validate our document before refering to the id
$xmldoc->validateOnParse = true;

function $id
{


}

$xmldoc->getElementById('$id')->tagName . "\n";





print $xmlDoc->saveXML();
?>

im new to this sort of this but what im trying to do is

make $id user inputted so if they wanted title it would file title from this file, im not sure how to go about writing a function for that

If I understand you right, you may have better luck using getElementsByTagName() -- since I can't see any IDs used within your XML.

No i want to right the function for $id, if thats possible?

where it will take the "search string" from the user php parse

[TheJoey]

Ok, my mistake there is a user field, how do i make it so that the userfield becomes the search string, do i need a function write?
