setExternalSchemaLocation help

["Skarupa, Steven" <ss...@epotec.com>]

Hi.
 
I'm relatively new to mod_perl and Xerces. I am currently using the Xerces
parser in order to take advantage of the ability to bounce some xml
documents against schemas for the purpose of simple validation.
 
I need to set the schema location dynamically at runtime and can not figure
out how to convert the C++ setExternalSchemaLocation call to Perl.  
 
Here is the related code:
 
 eval {
         open INPUT_FILE, $file or die "could not open file because $!";
         # Do some file slurping here.
         undef $/;
         my $file_contents =<INPUT_FILE>;
         close INPUT_FILE;
         $parser->setExternalSchemaLocation("http://www.test.com
<http://www.test.com>  is_blank.xsd");
         $parser->parse
(XML::Xerces::MemBufInputSource->new($file_contents));
    };

I receive the following error at STDOUT:
 
    Can't locate auto/XML/Xerces/SAX2XMLReader/setExternal.al in @INC (@INC
 
I have:
   > Studied the C++ API documentation (but I'm not a C++ coder so it's only
faintly understandable to me)
   > Read through the schema information on
http://xml.apache.org/xerces-c/schema.html
<http://xml.apache.org/xerces-c/schema.html>  <http://www.apache.org/xml> 
   > Searched the xerces-p-dev archives - no luck.
   > tried to get a grip on what the Xerces.pm wrapper module is doing
(that's where I found the setExternalSchemaLocation call).
   > mungled the SAX2Count.pl script into my own version that works
"dynamically" and it seems to work fine if I remove the offending
setExternalSchemaLocation call and add the schema line to the xml file
itself.
 
Can anyone help me?  
 
Thanks!
-Steve
