PHP DOMDocument getElementsByTagname?

Question

This is driving me bonkers... I just want to add another img node.

$xml = <<


        

Answer 1

DOMDocument::getElementsByTagName doesn't return an array, it returns a DOMNodeList. You need to use the item method to access its items:

$album = $xmlDoc->getElementsByTagname('album')->item(0);

Answer 2

// Parse error: syntax error, unexpected '[' in /Applications/XAMPP/xamppfiles/htdocs/admin/tests/DOMDoc.php  on line 17

you cant do this in php

$album = $xmlDoc->getElementsByTagname('album')[0];

you have to do this

$albumList = $xmlDoc->getElementsByTagname('album');
$album = $albumList[0];

EDIT: getElementsByTagname returns an object so you can do this (above code is incorrect)...

$album = $xmlDoc->getElementsByTagname('album')->item(0);

This error....

// Fatal error: Call to undefined method DOMNodeList::appendChild() in /Applications/XAMPP/xamppfiles/htdocs/admin/tests/DOMDoc.php on line 19

DOMNodeList doesnt have an appendChild method. DOMNode does.
