Hi,

Dunno about schema generation. It seems like you do not want to generate the XSD itself but rather use it as part of a validation scheme.

A good validator is found in XML::Xerces module. But beware, you'll have to first compile Xerces-C library as a back-end. Then, you can use the following code sample for validation purposes:

  use strict;
  
  use XML::Xerces;
  
  XML::Xerces::XMLPlatformUtils::Initialize ();
  
  my $parser = XML::Xerces::SAXParser->new; # SAXParser or XercesDOMPa
+rser
  
  my $options = {
    setDoNamespaces                 => 1,
    setDoSchema                     => 1,
    setErrorHandler                 => XML::Xerces::PerlErrorHandler->
+new,
    setExitOnFirstFatalError        => 0,
    setExternalSchemaLocation       => 'http://www.spiritconsortium.or
+g/XMLSchema/SPIRIT/1.2 /data/101/users/xavier_data/soc/BFD/Schema-1.2
+/index.xsd',
    setValidationConstraintFatal    => 0,
    setValidationSchemaFullChecking => 1,
    setValidationScheme             => $XML::Xerces::AbstractDOMParser
+::Val_Always,
  };
  
  $parser->$_ ( $options->{$_} ) for keys %$options;
  
  eval { $parser->parse ( shift ) };
  
  XML::Xerces::error ( $@ ) if $@;
  
  XML::Xerces::XMLPlatformUtils::Terminate ();

I'm using here cheesy setExternalSchemaLocation scheme because in my example, SPIRIT Schema URL is dead and I had to install the XSD files locally.

Hope this helps,

Cheers,
