NAME

       XML::Validate::LibXML - Interface to LibXML validator

SYNOPSIS

         my $validator = new XML::Validate::LibXML(%options);
         if ($doc = $validator->validate($xml)) {
           ... Do stuff with $doc ...
         } else {
           print "Document is invalid\n";
         }

DESCRIPTION

       XML::Validate::LibXML is an interface to the LibXML validating parser which can be used
       with the XML::Validate module.

METHODS

       new(%options)
           Returns a new XML::Validate::LibXML instance using the specified options. (See OPTIONS
           below.)

       validate($xml)
           Returns a true value if $xml could be successfully parsed, undef otherwise.

           Returns a true (XML::LibXML::Document) if $xml could be successfully parsed, undef
           otherwise.

       last_dom()
           Returns the DOM (XML::LibXML::Document) of the document last validated.

       last_error()
           Returns a hash ref containing the error from the last validate call. This backend
           currently only fills in the message field of hash. Note that the error gets cleared at
           the beginning of each "validate" call.

       version()
           Returns the version of the XML::LibXML module that is installed

OPTIONS

       XML::Validate::LibXML takes the following options:

       strict_validation
           If this boolean value is true, the document will be validated during parsing.
           Otherwise it will only be checked for well-formedness. Defaults to true.

       base_uri
           Since the XML document is supplied as a string, the validator doesn't know the
           document's URI. If the document contains any components referenced using relative
           URI's, you'll need to set this option to the document's URI so that the validator can
           retrieve them correctly.

ERROR REPORTING

       When a call to validate fails to parse the document, the error may be retrieved using
       last_error.

       On errors not related to the XML parsing, these methods will throw exceptions.  Wrap calls
       with eval to catch them.

DEPENDENCIES

       XML::LibXML

BUGS

       last_error currently returns a hash ref with only the message field filled. It would be
       nice to also fill the line and column fields.
