NAME

       XML::LibXML::Schema - XML Schema Validation

SYNOPSIS

         use XML::LibXML;
         $doc = XML::LibXML->new->parse_file($url);

         $xmlschema = XML::LibXML::Schema->new( location => $filename_or_url, no_network => 1 );
         $xmlschema = XML::LibXML::Schema->new( string => $xmlschemastring, no_network => 1 );
         eval { $xmlschema->validate( $doc ); };

DESCRIPTION

       The XML::LibXML::Schema class is a tiny frontend to libxml2's XML Schema implementation. Currently it
       supports only schema parsing and document validation. As of 2.6.32, libxml2 only supports decimal types
       up to 24 digits (the standard requires at least 18).

METHODS

       new
             $xmlschema = XML::LibXML::Schema->new( location => $filename_or_url, no_network => 1 );
             $xmlschema = XML::LibXML::Schema->new( string => $xmlschemastring, no_network => 1 );

           The  constructor of XML::LibXML::Schema needs to be called with list of parameters. At least location
           or string parameter is required to specify source of schema. Optional parameter no_network set  to  1
           cause  that  parser  would  not access network and optional parameter recover set 1 cause that parser
           would not call die() on errors.

           It is important, that each schema only have a single source.

           The location parameter allows one to parse a schema from the filesystem or a (non-HTTPS) URL.

           The string parameter will parse the schema from the given XML string.

           Note that the constructor will die() if the schema does not meed the constraints of  the  XML  Schema
           specification.

       validate
             eval { $xmlschema->validate( $doc ); };

           This  function  allows one to validate a (parsed) document against the given XML Schema. The argument
           of this function should be a XML::LibXML::Document object. If this function succeeds, it will  return
           0,  otherwise  it will die() and report the errors found. Because of this validate() should be always
           evaluated.
