Thanks
dasgar for sample input. I have used
XML::Twig and xpath expression to do this.
use strict;
use warnings;
use XML::Twig;
my $twiga=XML::Twig->new(); # create the twig for data1
$twiga->parsefile( 'data1.xml'); # build it
my $twigb=XML::Twig->new(); # create the twig for data2
$twigb->parsefile( 'data2.xml'); # build it
foreach my $t ($twiga->get_xpath('//host[@id]')) {
my $att = $t->{'att'}->{'id'};
unless ($twigb->get_xpath("//host[\@id='$att']")) {
print "$att is not found in data2.xml\n";
}
foreach my $alias ($t->findnodes("host-alias")) {
my $web = $alias->text;
unless ($twigb->get_xpath("//host[\@id='$att']/host-alias[stri
+ng()='$web']")) {
print "$att with $web is not found in data2.xml\n"
}
}
}
