If you want to just access XML values you don't need to use XPath to find this informations. You can use it, but the XPath implementation in Perl (XML::XPath), in my opinion, is not very intuitive to use.

What you can do is to use some module that loads XML into a HASH tree, and access the values directly from the tree. You can take a look at XML::Simple (more popular) and XML::Smart (well, I'm the author of it, so I shouldn't say what is better).

Well, the main idea of XML::Smart is to enable the use of XML by programmers without need to really know the XML format. Here's a simple example of how to do what you want:

  use XML::Smart ;
  
  my $xml = new XML::Smart('available_batchnyyn.xml');
  
  my @avaliables = @{ $xml->{AvailableBatch}{Available} } ;
  
  foreach my $avaliables_i ( @avaliables ) {
    my $part = $avaliables_i->{Part} ;
    my $qty  = $avaliables_i->{Qty} ;
    print "Part: $part ; Qty: $qty\n" ;
  }
