in reply to XPATH DOM traverse html/xml

I don't know which module you use, but with XML::Twig you can use the xpath method like this, for example:

perl -MXML::Twig -E'my $t=XML::Twig->parse( "my.xml"); foreach my $e ($t->descendants( "#ELT")) { say $e->xpath; }'

    XML::Twig is one of the many things that keeps me using Perl. (It's one of the modules my personal 'M.pm' module loads -- 'M.pm' so I can do perl -MM -lwe ....) So, thanks again, mirod.

    The first thing that came to mind was:

    perl -MXML::Twig -E 'XML::Twig->new( twig_handlers => { _all_ => sub { say $_->xpath } })->parsefile(shift)'

    ...which isn't so different from what you wrote. But, the following has the benefit of not requiring the loading of the entire file (correct?):

    perl -MXML::Twig -E 'XML::Twig->new( start_tag_handlers => { _all_ => sub { say $_->xpath } })->parsefile(shift)'

      Absolutely, the way you wrote it is more efficient. I just went for the easiest way I could think of, not knowing enough about the OP's exact constraints.
