( #3333=superdoc: print w/ replies, xml ) Need Help??

The code would look like this:

my ($message_count, $sent_count); my $parser = new XML::Rules ( rules => [ _default => 'content', message => sub { $message_count++; Mail::Sendmail::sendmail( from => $_[1]->{from}, to => $_[1]->{to}, subject => $_[1]->{subject}, body => $_[1]->{body}, ) or warn "Mail Error: $Mail::Sendmail::error"; $sent_count++ unless $Mail::Sendmail::error; return; }, messages => sub { print "SAX Mailer Finished\n$sent_count of $message_count mess +age(s) sent\n"; return; } ]); $parser->parsefile($file);
or, if you did not want to use any external variables:
my $parser = new XML::Rules ( rules => [ _default => 'content', message => sub { $_[3][-1]->{message_count}++; Mail::Sendmail::sendmail( from => $_[1]->{from}, to => $_[1]->{to}, subject => $_[1]->{subject}, body => $_[1]->{body}, ) or warn "Mail Error: $Mail::Sendmail::error"; $_[3][-1]->{sent_count}++ unless $Mail::Sendmail::error; return; }, messages => sub { print "SAX Mailer Finished\n$_[1]->{sent_count} of $_[1]->{mes +sage_count} message(s) sent\n"; return; } ]); $parser->parsefile($file);
or
my $parser = new XML::Rules ( rules => [ _default => 'content', message => sub { my ($tag_name, $tag_hash, $context, $parent_data) = @_; $parent_data->[-1]->{message_count}++; Mail::Sendmail::sendmail( from => $tag_hash->{from}, to => $tag_hash->{to}, subject => $tag_hash->{subject}, body => $tag_hash->{body}, ) or warn "Mail Error: $Mail::Sendmail::error"; $parent_data->[-1]->{sent_count}++ unless $Mail::Sendmail::err +or; return; }, messages => sub { print "SAX Mailer Finished\n$_[1]->{sent_count} of $_[1]->{mes +sage_count} message(s) sent\n"; return; } ]); $parser->parsefile($file);

I guess I should add a few more ways to add data to the parent node. Apart from 'attributename' that sets (and if needed overwrites) the attribute and '@attributename' that appends the value to the array I should also allow '+attributename' and '.attributename'. '-attributename' is not needed, but I wonder whether to add '*attributename'.

With the '+attributename' the code would look like this:

my $parser = new XML::Rules ( rules => [ _default => 'content', message => sub { Mail::Sendmail::sendmail( from => $_[1]->{from}, to => $_[1]->{to}, subject => $_[1]->{subject}, body => $_[1]->{body}, ) or warn "Mail Error: $Mail::Sendmail::error"; return '+message_count' => 1, '+sent_count' => ($Mail::Sendmai +l::error ? 0 : 1); }, messages => sub { print "SAX Mailer Finished\n$_[1]->{sent_count} of $_[1]->{mes +sage_count} message(s) sent\n"; return; } ]); $parser->parsefile($file);

All code except the last snippet is tested :-)

I'll have a look at SAX, currently the module sits on top of XML::Parser:Expat, but I think it should not be a big deal to change that. Or to change the code so that you can choose what to use.
