in reply to parsing xml file using LIBXML

Various points to make...

  • as mirod says, that's an ugly piece of XML. But that's not the problem we're here to solve today...
  • getElementsByTagName works only on a Document object, not on any element: it finds all the elements with the given name anywhere in the document. I don't think that's what you need.
  • to do the match, you could use getAttribute() to get the value of the use attribute, and then use a regexp or something similar to test if it contains the value passed from the command line. Like:
    $attrValue =~ /\Q$param\E/
    where the \Q...\E is to avoid strange characters from being interpreted by the regexp engine.
  • learn XPath. Really do. That whole program can be reduced to a single XPath query. And it would be easier to read.

Most of my code is tested...

Perl is strongly typed, it just has very few types (Dan)
