Thread: validate XML doc against its XSD on Win32 platform

    As far as I know, Xerces is still the best option out there

for validating XML documents against W3 Schemata. Admittedly

it's been awhile since I attempted it with LibXML, but Xerces

has always been highly regarded as far as it's correctness (though

the Perl module itself is a bitch to install!).



I wrote a small self-contained Win32 application which shows

how this is done. You can get it here:



http://sunsite3.berkeley.edu/ead/tools/schema_validate



Double click to install, no perl installation required (it's

included in the .exe). Contact me if you're leery of exes and

want a zip or something.



Best regards,



Arvin

I have heard rumors of unspecific "problems" with
XML::LibXML's  
schema validation, but I have not experienced any of them
myself. As  
far as I know, it's still undocumented, but has worked
without a  
hitch for me in many applications:

     my $parser = new XML::LibXML;
     my $validator = new XML::LibXML::Schema (location =>
  
"schema.xsd");
     $doc = $parser-> parse_string($content);
     eval { $validator-> validate($doc) };
     if ($) {
         ...
     }
     else
     {
         ...
     }

Ahem, I only just realized you said LibXML was not an option
under  
Win32.  Sorry.

Danny,

stop this FUD, XML::LibXML::Schema API *is* documented, the 
documentation POD is included in the distribution package.
On UNIX, 
even manual pages are generated (man XML::LibXML::Schema). 

I guess that your "undocumented" means that you do
not see the 
documentation on Randy Kobes' http://kobesearch.cpan.o
rg/. I do not 
know, why Randy's engine ignores some of the .pod files,
probably 
it's because for some modules, there is no corresponding .pm
file. 

You can still find all the documentation on-line using the
good old 
CPAN-search site:

I got the Xerces stuff working.  Just followed the directions.  



As with so many other chores, the 'doing it' was straight forward.  The
'figuring out which way to do it is better/best' was a pain. 



The Xerces-p distribution comes with some examples including
'validate.pl' and is exactly what I was trying to do.  It reports
errors by line and column and schema error.  Perfect.



Thanks for all the info.
