You need a better understanding of how the XML source relates to the
source tree.

At http://skew.org/xml/stylesheets/treeview/html/
I have an XPath/XSLT node tree visualizer -- just a stylesheet
that you can apply to any XML source, and a CSS stylesheet that
is used by the result.

See the sample_output.html file there for an idea of what to expect. It was
the result of applying the stylesheet to sample_input.xml.

A version that outputs ASCII instead of HTML is at 
http://skew.org/xml/stylesheets/treeview/ascii/
