how to do get digit numbers like -,.?

virudinesh has asked for the wisdom of the Perl Monks concerning the following question:

use warnings;
use strict;

my @f =( "Figure. 89-9","Figure 12-8","Figure 1.2");
foreach(@f)
{
 if($_=~m/fig(. |[a-z])*(\d+)(\-(\d+))?/i)
                {
                print "  $2-$4 \n";
                }
}
[download]

its output comes like

89-9 12-8 1-

but am need output like this one 89-9 12-8 1.2

how to print both one's - (or). how to handle both in single regular expression

Just expanding upon your good answer to include the abbreviation 'Fig': `perl -E 'my @f =("2013-06-01", "fig 1-1", "Fig. 2.2", "Figure. 89-9"," +Figure 12-8","Figure 1.2"); foreach (@f) { print " $1\n" if /fig(?:ure)?\.?\s(\d+[-.,]\d+)/i; }' 1-1 2.2 89-9 12-8 1.2` [download]	[reply] [d/l]

hdb gave you a solution, but just to make sure that you understand your error, your problem simply comes from the fact that your regex does not include the dot.	[reply]

Use a "character class" or an alternation, perlintro shows examples of both	[reply]
