php domDocument check node exists

checking for a node to exist in an xml file using php

[liam_85]

Hello,

This is my first time posting a problem. I would like to check if an element exists in an xml file through php. Does anyone know how to go around this?

By ID you can do:

DomDocument->get_element_by_id ( string $id )

When it succeeds, then the node exists.
