XML file reading - stylesheet issues

Hi

When i try to read the following XML file and add it to a treeview i run into problems with two methods
a) text read
b) xml read

The issue is the 2nd line, the <?xml-stylesheet

IF i remove the "<?xml-stylesheet " line, i can get the treeview being populated on,

with it there, no, i found a code sample which used an XML reader and the use of reader.MoveToContent();
however this results in just one node, the top node.

>> I am after pointers how to respove this issue as i don't want to have to manually edit XML files to remove the stylesheet statement.

Thanks in advance
