Remove all the uninteresting characters from your data before testing for match, e.g. s/[^a-zA-Z0-9]//g.

    hdb, but how can I make it back as it was...? if I remove the uninteresting characters, the there will be No space or new line in the desired output.

      Work on a copy of the data for the testing...

      UPDATE: I think I now understand what you want. Try something like this:

      my $regex = join '\s+', qw( New Store Opening Promenade in Crocker Par +k Rack Nordstrom Rack is a division of Nordstrom ); $out = $1 if ($data_main =~ /($regex.*)/is);
        Thanks hdb, I checked, this will work for me in 90% cases... Thanks for your time... :)
        Hi Hdb, I tried something like this, but not working. Is there any way to define that string seperately as I done here.
        $qqq = "New Store Opening Promenade in Crocker Park Rack Nordstrom Rac +k is a division of Nordstrom"; my $regex = join '\s+', qw($qqq); $out = $1 if ($data_main =~ /($regex.*)/is);

        Its the same code except that string is defined separately. Will this not work? or is there another way to define that string seperately... Actually I want a global solution for this. I have may files similar which need to be done. thats why I need a global solution & not a hardcoded solution. Thanks

      If you're not interested in them, why put them back? As choroba suggested, a clearer statement of the problem may lead to better understanding for all, including yourself.
