How can I use PHP to retrieve the Namespace Elements from a list feed?

[Matt]

I am trying to get the Value of the name space elements from a list feed, 
but I can't do it.

getNameSpace returns an error that it is a call to an undefinded method. I 
have tried everyway of typing it out..

I can't split the listfeed by commas because some entries contain commas, 
all the information is right there in the feed, but I don't know how to 
access it.

I have tried to import it into simpleXML, but I get an unable to parse 
error. 

I am working off of modifying the code in the PHP library.

Please help.
