Why my code working...why my code is not working...

[prashantktyagi]

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;

How can I debug this behavior?

Um ... Use the built-in perl debugger -?

BTW "not working" is not a particularly descriptive problem statement.

As a side note, your title "Why my code working...why my code is not working..." is repetitive and unhelpful. A link to How do I compose an effective node title? is displayed every time you post. Please read and understand it.

You said: "It happened to work on same config test machine but not working in production." and "How can I debug this behavior?"
1. Determine the difference(s) between your Production machine and your test machine.
2. Correct the setup of the test machine to accurately reflect the Production world.
3. Debug your code on the test machine using your normal tools.
4. Deploy to production and observe the results.

As Tutorials Basic debugging checklist and brian's Guide to Solving Any Perl Problem say:

when you're not getting the values you're looking for, Dumper it

You can use   use Data::Dump;dd [ join "\n", $patch_node ];
