Here's an example using XML::Rules. The only tricky part is the DOCTYPE handler, which I'm not totally sure about, but it works for your example:
use XML::Rules;
use Data::Dumper;

my $xml = <<XML;
<?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>
XML

my @rules = (
  '^test' => sub { $_[1]->{name} eq 'Import Test Suite' },
);

my $xr = XML::Rules->new(
  style => 'filter',
  rules => \@rules,
  handlers => { Doctype => sub {
    my (undef, $name, $sysid) = @_;
    print qq(<!DOCTYPE $name SYSTEM "$sysid">\n);
  }},
);
