Did you copy & paste or retype my suggestions? I suspect you retyped and
called first_elt() on $root, which will not work (obviously :-> ) because
$root is a XML::Twig::Elt (obtained from calling root() on $twig) and,
as you noticed, there is no sub first_elt in XML::Twig::Elt.

If you look again at the examples, you will surely note that the first
one uses $twig (a XML::Twig Object), whereas the other two use $root (a
XML::Twig::Elt Object). I hope this clarifies things a little bit.

Andreas, your explication is quite clear.  Thanks,

My new question is what is the best way to parse the following XML file. This is just a part
 of long long file. I want the text of <configName>  <configType> and <type>, <type> is under
 <Arg> . Now, I can get <configName> and <configType>. Then, I need to enter <Ports>, <Port>,
 <Args>  and <Arg> levels and then to get <type> info. Can I just jump some of the tags and g
et <type>  directively. I set 'type' at TwigRoots, doesn't work. 

Thanks,
Ying
