Perform an action if certain text exist in output (PERL)

Hello,

I'm attempting to write a tool that checks an IP address for existing PTR records then if there are no PTR records does a ping to see if it response.

Then if there is no response, it should print a message saying

This is what I have so far.

Code:
#!/usr/bin/perl
$nxdomain = "NXDOMAIN";
$ping = "100%";
while (defined($line = <>)) {
	chomp($line);
		print `nslookup $line`;
			if ($nxdomain) {
		print `ping -c 1 -w 2.0 $line`; }
			if ($ping) {
		print "IP Address '$line' is available.\n";
			}
	}

What I can't seem to get to work are the if statements for if the text NXDOMAIN is in the output and if 100% is in the output. It just goes ahead with the nslookup and then goes ahead with the ping.

Any suggestions?
Thanks!
