Simple problem, hope simple solution.

How to edit element in XML file?

Here what I have been trying...

<?php
$dom = new DOMDocument;
$dom->load('XML/sample.xml');

if ($dom->getElementsByTagname('Static_IP')) {
$Static_IP = $dom->getElementsByTagname('Static_IP');
$Static_IP_value = $Static_IP->item(0)->firstChild->nodeValue;

print "IP address: $Static_IP_value";

$IPaddress =10.10.1.1;

????????????
How to add this variable into te element name Static_IP
????????????

$dom->formatOutput = true;
$sample = $dom->saveXML();
$dom->save('XML/sample.xml');

?>

If adding an attribute to the existing element, use setAttribute()

If creating an entirely new element, use createElement() + appendChild()

As I said, simple solution that I could not find at the moment 🙂

$Static_IP_value = '10.10.10.111';
$dom->getElementsByTagname('Static_IP')->item(0)->firstChild->nodeValue = $Static_IP_value;
