my $parser=new XML::DOM::Parser;

my $doc=$parser->parsefile('C:\perl\perl_tests\xmlin.xml') or die$!;
my $root=$doc->getDocumentElement();

my @address=$root->getElementsByTagName("address");

foreach my $address(@address)
{
    if($address->getAttribute("name") eq "tayal")
    {
        if($address->getAttribute("id")=='70889')
        {
         $address->setAttribute("name","Joey");
         $address->setAttribute("id","67890");
         my $temp1=$address->getAttribute("name");
         my $temp2=$address->getAttribute("id");
         print("$temp1\t$temp2\n\n");
         }
