[p2p-hackers] DTD for search requests

[larytet.8753341 at bloglines.com]

is anybody aware of such DTD ?
the following is part of XML i would like
to see
<file>
  <fileName>Linux tutorial</fileName>
  <fileType>document</fileType>

  <fileSizeMax units="Kbytes">10</fileSizeMax>
</file>

i need something
flexible, because sometimes i will look for folders and sometimes for chat
rooms ID's

thanks
