Win32::SetCwd("/temp");

my $xpath = XML::XPath->new("c:/temp/results.xml");
my $nodeset = $xpath->find('/XMLOut/Check[@Grade="2"]/Detail/UpdateData');

print "nodebefore\n";
foreach my $node ($nodeset->get_nodelist){
$element= XML::XPath::XMLParser::as_string($node);
my $xp = XML::XPath->new(context => $element );
my $nodeset1 = $xp->find("//@KBID");

syedahmed, just a suggestion, you will get a better response when posting in the correct forum.

Dr. Script, can you move this to the XML forum?

[khp]

If I'am understanding you correctly this is the line that is causing you problems

my $nodeset1 = $xp->find("//@KBID");


At any rate I don't understand why you don't just write


my $nodeset1 = $xp->find("@KBID");
