Re^3: Easy XML-parser that can handle large file?

Nice.

In case you, or the reader, don't know: in handlers $_ is aliased to $_[1], so you can write ,$_->get_xpath(...) instead of $_[1]->get_xpath(...). Beyond saving 3 characters each time, I am used to $_ meaning "the current element" within a handler, and I find it easier to read.

a 'nice' from the module author... i'm honored... ;=)

I never noticed this feature of $_ set to $_[1] (or well, i used incosciously..)

May be worth to add some line in the Synopsis:

para    => sub { $_[1]->set_tag( 'p')  }, # change para to p (handlers
+ receive $twig and $element as argouments)
para    => sub { $_->set_tag( 'p')  },    # change para to p ($_ is al
+iased to $_[1] for convenience  )


###and in the corpus of the docs:

$_ is also set to the element (ie: $_[1]), so it is easy to write inli
+ne handlers like

The first example in the synopsis uses $_, I added a comment to make it more explicit. It's also mentioned in the XML::Twig 101 section.

I know that the docs are a bit overwhelming and hard to read.

The main reason is probably that XML::Twig it's too big. This comes from a decision I made, a long time ago, to have just 1 massive module, instead of several ones. The reason at the time was to allow users to install the module easily, especially on Windows, by simply copying Twig.pm in the proper place. At the time there were no Strawberry Perl, perlbrew or local::lib... If I were to start again I would certainly break up the module in several sub-modules (as with XML::Twig::XPath).
