in reply to How to fetch a portion of a XML file to save it in another xml file

Note, I closed your suite for you.

use strictures;
use XML::LibXML;

my $before = <<"";
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Automation Suite" verbose="1" parallel="false">
  <test name="Configuration Restore Test Suite">
    <classes>
      <class name="com.qa.testsuite.ConfigurationRestoreTests" />
    </classes>
  </test>
  <test name="Import Test Suite">
    <classes>
      <class name="com.qa.testsuite.ImportTests" />
    </classes>
  </test>
</suite>

my $doc = XML::LibXML->new->load_xml( string => $before );

my ( $test_suite ) = $doc->findnodes('/suite/test[@name="Import Test S
+uite"]');

$doc->setDocumentElement( $test_suite );

print $doc->serialize; # or $doc->toFile(...)

This may or may not be sane given the DTD but it gives the output you want. Update, there is a toFile() method for the doc.

    Thanks for your input. It's working partially. In case, if I want to add multiple test nodes based on user choice how can I do that. In this example, I can extract only one node based on XPath.

    Also, I want to include suite node in the new.xml file.

      I do think it's time for you to start reading the XML::LibXML docs. See if you can at least get the multiple test nodes captured/found, it's quite a small adjustment. Post what you come up with and if you can't work it all out, I or someone will help you finish.

      Oh, ok! You wore me out and I wrote it yesterday and there's no reason for it to die of bitrot in some corner of my disk. I do hope you will try to pick up a little of it and not just get others to write it for you. 

      my $doc = XML::LibXML->new->load_xml( string => $before );

my @tests = $doc->findnodes('/suite/test[@name="Import Test Suite"]');

my $suite = $doc->getDocumentElement;

$suite->removeChildNodes;

$suite->addChild($_) for @tests;

print $doc->serialize(1); # or $doc->toFile("new.xml")
