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 );
      $xmlschema = XML::LibXML::Schema->new( string => $xmlschemastring );
      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 );
          $xmlschema = XML::LibXML::Schema->new( string => $xmlschemastring );

        The constructor of XML::LibXML::Schema may get called with either one of two parameters. The
        parameter tells the class from which source it should generate a validation schema. 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 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.
