Yup, that was the kind of method I was assuming.  I've decided for the
pre-generated files this will be an ok way to do it - it doesn't matter
how long it takes (within reason) to create those.  For those that are
dymanically created in a cocoon pipeline, this seems less reasonable.

I suppose another way to do this would be to create an intermediate
file which contains all the possible @code values with a list of
what files have that code, so I could get the information by opening
only one file, which would be quicker.  So something like:
<foo>
<bar code="123">
<file name="file1.xml"/>
<file name="file2.xml"/>
<file name="file3.xml"/>
<file name="file4.xml"/>
</bar>
<bar code="134">
<file name="file1.xml"/>
<file name="file4.xml"/>
</bar>
<bar code="139"/>
</foo>
