[xml] sgi regression failure

[Martin Cole <mjc sci utah edu>]

I ran into this because of a failure on this platform finding a dtd from
my catalog entry.  (works on other platforms)

I do the following and fail on this platform:


  xmlInitializeCatalog();
  xmlCatalogAdd(BAD_CAST "public", BAD_CAST "-//SCIRun/Network DTD, 
                BAD_CAST "path to the dtd file");

  /* create a parser context */
  ctxt = xmlNewParserCtxt();
  if (ctxt == 0) {
    std::cerr << "ComponentNode.cc: Failed to allocate parser context
\n";
    return -1;
  }
  /* parse the file, activating the DTD validation option */
  doc = xmlCtxtReadFile( ctxt, argv[1], 0, (XML_PARSE_DTDATTR | 
                                            XML_PARSE_DTDVALID) );



volume-rendering.srn:2: I/O error : failed to load external entity
"network.dtd"<!DOCTYPE network PUBLIC "-//SCIRun/Network DTD"
"network.dtd">
                                                               ^
volume-rendering.srn:4: validity error : Validation failed: no DTD found

So i ran the regressions (whose output follows). It looks like the
regexp xpath tests fail which is likely why validation fails.

Any suggestions for where I should go from here?
