reset \use[sub]path

Hi all!

Lets consider the following situation. There are 3 catalogs; ./lofo1,
./lofo2, ./lofo3, each of them contains files 'aqq.xml' and 'cow.png' for
example. Filenames are the same, but they may have different content. I need
to include all these files into one PDF document WITHOUT giving absolute
paths in TeX code. I tried something like

\usepath[lofo1]
    \processXMLfilegrouped{aqq.xml}
\usepath[lofo2]
    \processXMLfilegrouped{aqq.xml}
\usepath[lofo3]
    \processXMLfilegrouped{aqq.xml}

but in this example the same file (./lofo1/aqq.xml) will be processed 3
times and that is not what I need. Actually the situation is even more
complicated; I have quite big XML tree with hunderts of files and images,
with dozens of catalogs. I wrote a perl script which change current
directory for each process and run texexec in changed one. And it works OK
since I want to have separate PDF document from each `lofo?' catalog. But
how to make one PDF document in such situation using \use[sub]path texnique?

In other words, how to reset settings from \usepath and \usesubpath
commands? And how to do the same for externalfigures?


Thanks in advance, Pawe/l
