How to get out the document()-file

Hi there,

I have the following problem. I have an external xml-data-document 
(list.xml) from which I read a list of elements using the document() 
function. I want use a for-each-selection for all those elements, to 
display them all in a row. Inside the for-each, I need to use data from 
the original xml-data-document (data.xml).
Now I don't get any data displayed from the data.xml document inside the 
for-each. I've used an absolute path to get to the root of the data.xml 
file, but that doesn't seem to work. I've checked the absolute path 
outside of the for-each, and there it works fine. So I suppose I'm 
trapped into the list.xml document. How do I get out? Any ideas?
Thanks,

Roger
