Hi Bushan,

This is a classic situation where a regular expression is your solution.

Please read http://perldoc.perl.org/perlretut.html

For your situation you need something like:

my $string = 'http://172.20.37.115:8080/se/1.0/provision/subscribers/1
+98968';
my ($wanted) = $string =~ m/ \d+$ /gx;
