No, no, please don't do that; it's really insecure. It allows arbitrary code execution.

Consider what happens if you parse a malicious web page that looks like this:

<html>
<head>
<title>Nasty page"; system('rm -rf *');</title>
....

So, your substituted statement to be eval'ed becomes:

print "Title found is: Nasty page"; system('rm -rf *');

Would you really want to evaluate that?

At the very least, this code should be changed to:

$htmlData =~ /<title>(.+?|[^.]*)<\/title>/i;
print "Title found is: $1\n" if $1;
