XML::DOM::ValParser(3)User Contributed Perl DocumentatioXML::DOM::ValParser(3)

NAME
       XML::DOM::ValParser - an	XML::DOM::Parser that validates	at parse time

SYNOPSIS
	use XML::DOM::ValParser;

	my %expat_options = (KeepCDATA => 1,
			     Handlers => [ Unparsed => \&my_Unparsed_handler ]);
	my $parser = new XML::DOM::ValParser (%expat_options);

	eval {
	    local $XML::Checker::FAIL =	\&my_fail;
	    my $doc = $parser->parsefile ("fail.xml");
	    ...	XML::DOM::Document was created sucessfully ...
	};
	if ($@)	{
	    # Either XML::Parser (expat) threw an exception or my_fail() died.
	    ...	your error handling code here ...
	    # Note that	the XML::DOM::Document is automatically	disposed off and
	    # will be garbage collected
	}

	# Throws an exception (with die) when an error is encountered, this
	# will stop the	parsing	process.
	# Don't	die if a warning or info message is encountered, just print a message.
	sub my_fail {
	    my $code = shift;
	    die	XML::Checker::error_string ($code, @_) if $code	< 200;
	    XML::Checker::print_error ($code, @_);
	}

DESCRIPTION
       Use XML::DOM::ValParser wherever	you would use XML::DOM::Parser and
       your XML	will be	checked	using XML::Checker at parse time.

       See XML::DOM for	details	on XML::DOM::Parser options.  See XML::Checker
       for details on setting the fail handler (my_fail.)

       The following handlers are currently supported, just like
       XML::DOM::Parser: Init, Final, Char, Start, End,	Default, Doctype,
       CdataStart, CdataEnd, XMLDecl, Entity, Notation,	Proc, Default,
       Comment,	Attlist, Element, Unparsed.

XML::DOM::ValParser
       XML::DOM::ValParser extends from	XML::Checker::Parser. It creates an
       XML::Checker object and routes all event	handlers through the checker,
       before processing the events to create the XML::DOM::Document.

       Just like XML::Checker::Parser, the checker object can be retrieved
       with the	getChecker() method and	can be reused later on (provided that
       the DOCTYPE section of the XML::DOM::Document did not change in the
       mean time.)

       You can control which errors are	fatal (and therefore should stop
       creation	of the XML::DOM::Document) by filtering	the appropriate	error
       codes in	the global $XML::Checker::FAIL handler (see "ERROR_HANDLING"
       in XML::Checker)	and calling die	or croak appropriately.

       Just like XML::Checker::Parser, XML::DOM::ValParser supports the
       SkipExternalDTD and SkipInsignifWS options. See XML::Checker::Parser
       for details.
