in reply to Recursion and XML::Twig

It's more than a message; it's a fatal error.

If you run it under diagnostics:

Uncaught exception from user code: calling depth after parsing is finished at /opt/perl-5.8.6/lib +/site_perl/5.8.6/i686-linux/XML/Parser/ line 474 at /opt/perl-5.8.6/lib/site_perl/5.8.6/i686-linux/XML/ line +192 XML::Parser::parse('XML::Twig=HASH(0x81ec750)', '<node id="17" +><content>foo bar</content><child file="19.xml" ...') called at 48649 line 9

Frankly, I would not expect the parser to brook such treatment. Why not create a new parser in onChild?:

sub onChild { my ($t, $child) = @_; my $atts = $child->atts; XML::Twig->new( twig_handlers => { child => \&onChild } ) ->parsefile($atts->{file}); }

    I did not recognize that it is a fatal error. Of course, the idea with a new twig object makes more sense and works perfectly.

    Thanks a lot :)

    reading between the lines is my real pleasure
