That tells me absolutely nothing about the structure of either. 

Let's be concrete. Is the outermost element of your source XML caled <row>
or is it called <in_proc>? If it's called <row> then I can point to one set
of errors in your stylesheet, if it's called <in_proc> then I can point to a
different set. It's possible that your stylesheet is written to allow it to
be either, but that seems unlikely.
