Thank you for the hint on using po. I am very new to all things Mac (
although, I was there when the first Mac was shown in Melbourne, way before
I ever saw a PC.... ), and I am still working out how the debugger in XCode
works. As for NSMXLNode, I moved to NSXMLElement to get access to
attributeForName, I was using NSXMLNode before that, still to no avail.

OK - I was trying that and got nothing back. As in, the debugger seemed to
be telling me the value was null.

Thanks - hopefully this is going to really help me work out what is going
wrong here, although I suspect we're going to move to the DOM implimentation
I found in the docs last night. Using a standard interface would really
help me, especially as there doesn't seem to be any intellisense in XCode.
Thanks for your help, it's much appreciated.
