=head1 NAME
|
||||
|
||||
SOAP::WSDL::Expat::MessageParser - Convert SOAP messages to custom object trees
|
||||
|
||||
=head1 SYNOPSIS
|
||||
|
||||
my $parser = SOAP::WSDL::Expat::MessageParser->new({
|
||||
class_resolver => 'My::Resolver'
|
||||
});
|
||||
$parser->parse( $xml );
|
||||
my $obj = $parser->get_data();
|
||||
|
||||
=head1 DESCRIPTION
|
||||
|
||||
Real fast expat based SOAP message parser.
|
||||
|
||||
See L<SOAP::WSDL::Parser> for details.
|
||||
|
||||
=head2 Skipping unwanted items
|
||||
|
||||
Sometimes there's unneccessary information transported in SOAP messages.
|
||||
|
||||
To skip XML nodes (including all child nodes), just edit the type map for
|
||||
the message and set the type map entry to '__SKIP__'.
|
||||
|
||||
=head1 Bugs and Limitations

||||
|
||||

|
||||
|
||||
=item * Ignores all namespaces
|
||||
|
||||
=item * Does not handle mixed content
|
||||
|
||||
=item * The SOAP header is ignored
