Re: [PHP] Re: extracting data from XML file to PHP variable .. From: Kenn Murrah (kenn <email protected>)
Date: 03/31/04

Jason:

Yes, I am aware of the problem. However, for the very simple XML files
that I'm being asked to process, it's not an issue -- each file has, for
example, one and only one occurrence of "fullname" .... So, while I
realize that any solution I achieve for this project will have virtually
no portability to any future project, it would help me out of a terrible
mind in dealing with today's issue :-)

thanks.
