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

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

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.
