I have XML similiar to this: 
<result>
  <target type="aim">
    <tag1>123</tag1>
    <tag2>456</tag2>
    ...
  </target>
</result>

I want to match the 'tag'-tags with a regex or a nice xpath expression, but I fail doing so (maybe it is because I am a perl beginner).

So far I tried with regular expressions like: 
my $twig = new XML::Twig(twig_handlers =>
{
  "/result/target/tag[1-3]" => \&my_parsing_function,
});

and xpathes like: 
my $twig = new XML::Twig(twig_handlers =>
{
  "/result/target/tag[self::1 or self::2 or self::3]" => \&my_parsing_
+function
});

Unfortunately both won't work.
The regex version just ignores the tags, the xpath one fails, because of 'unrecongnised expression in handler'.

The Twig documentation mentions it supports 'xpath-like' expression, but it seems I am doing it the wrong way.
Is there a way to do the matching with twig or is it better to match the parent tag and do the matching afterwards?

Thank you!

(I hope my english is understandable enough to get an impression of what I want to do)
