Hi punitpawar,

You may not need to create a pattern by hand. In Perl, usually a tool has already been created for any common task you need to accomplish. Please see URI::Escape.

I don't know how your URL domain name got spaces in it, but you might be able to use URI::Escape::uri_unescape either before this point in your program, or here, to help you keep/get them out:

perl -MURI::Escape -E '

my $str = "www.abc%20.com";
say $str;

$str = URI::Escape::uri_unescape( $str );
say $str;

$str =~ s/\s//g;
say $str;
'

Output:

www.abc%20.com
www.abc .com
www.abc.com
[download]

Hope this helps!
