Hi Shlomi,

not sure this is the gist of your question, but one way to set up
catalogues with LibXML2 is to define some environment variables:

#!/bin/bash
XML_CATALOG_FILES=catalog.xml \
XML_DEBUG_CATALOG=1 \
xsltproc $@

You can also use an absolute path, of course.

With catalog.xml containing something like:

<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog">
 <group prefer="public">

  <public
   publicId="-//MiLu//DTD GurkML 0.1//DE"
   uri="catalog/GurkML.dtd"/>

  <public
   publicId="-//W3C//DTD XHTML 1.1 plus MathML 2.0//EN"
   uri="catalog/xhtml-math11-f.dtd"/>

  <system
   systemId="http://www.w3.org/TR/MathML2/dtd/xhtml-math11-f.dtd"
   uri="catalog/xhtml-math11-f.dtd"/>

  <system
   systemId="GurkML.dtd"
   uri="catalog/GurkML.dtd"/>

  <!-- When you are specifying an xml:base or uri attribute for use on
  a Microsoft Windows system, you must include the drive letter in the
  full URI syntax if you want it to work across processors. A Windows
  URI has this form:

   file:///c:/xml/docbook/

  Note the use of forward slashes, which is standard URI syntax. -->

 </group>
</catalog>

And then I store those DTDs below catalog/.

You can also resolve XSLT programs via a catalogue. And apparently you
can do URL rewriting using <rewriteSystem/>, <rewriteURI/>. And delegate
to other catalogues using <nextCatalog/>.

Hope this helps. Best regards,

Michael
