Hi, As my title describes. I had added one code to my existing script.
It happened to work on same config test machine but not working in production. 
my $patch_node = ($self->get_control->get_root->findnodes( '//package/
+patch' ))[0];
    my $patch_desc = $patch_node->findvalue('description');
    my $patch_name = $patch_node->findvalue('@name');
    my $patch_id   = $patch_node->findvalue('@patchcode' );
    my $target_version   = $patch_node->findvalue('@target_version' );

I am able to read patch_name,patch_id ,patch_desc but not target_version how ever these all are part of one tag.
How can I debug this behavior? Perl -v- 5.8.1
use XML::LibXML;
use XML::LibXSLT;
