Re: XML::Twig - Filtering and duplexing output to multiple output files

[Discipulus]

Hello ateague,
You had the right answer from Loops, i want to add only few words about your last question: "Is there a way to conditionally split target elements off into separate files and duplicate elements "outside" the target element to separate files without having to read the input file multiple times?" Even without a good module to multiplex the output you have no need to re-read the file. You can just build your custom print sub:

sub print_dup {
    
    foreach my $fh ( @previously_opened_handle_for_write ) { print {$f
+h} @_ }
}

You can also review similar question here at perlmonks as this one or my naive approch

The problem in this case is the flush method, which does some light magic to output the parts of the tree that haven't been output yet, and then updates the state of the XML::Twig object (so the next call to flush Just Works™). You can't call it twice in a row, with 2 different filehandles, it wouldn't work. That's why using IO::Tee is a brilliant idea.

obviously the author is right!
See indeed the docs about flush

You cannot hack it using print or sprint because they have to be used AFTER parse. lesson learned. Thanks.
