DOMDocument parsing

Posted on 16th Feb 2014 07:03 pm by admin

Hello, I am parsing an xml file from an API which I have converted into a DOMDocument in php. This is mostly fine but one problem I have is when I do this:
Code: [Select]$feeditem->getElementsByTagName('extra');
as part of a forall statment and the element extra doesn't exist in one of the feeditems I am iterating through in the forall condition then I get an error.

I think I need some kind of statment like:

Code: [Select]if ($feeditem->getElementsByTagName('extra') ISN'T NULL)
But don't know how to formulate it. Please help. Thanks.
