this is number 2,563 and rest of the text
after I export it into excel. Problem is that I\'m using custom tool (not programming language ) that excepts text as an input, regex pattern and export the output. This is why I need single pattern that eliminate space and produce either 88 or 2563 or any other number. The commas are every 3 positions obviously, so it can also be 1,345,321 as well as just single number 5 between "this is number .... and rest of the text"';
my $regex = qr~\b\d+(?:,\d+)*~mp;
if ( $str =~ /$regex/g ) {
print "Whole match is ${^MATCH} and its start/end positions can be obtained via \$-[0] and \$+[0]\n";
# print "Capture Group 1 is $1 and its start/end positions can be obtained via \$-[1] and \$+[1]\n";
# print "Capture Group 2 is $2 ... and so on\n";
}
# ${^POSTMATCH} and ${^PREMATCH} are also available with the use of '/p'
# Named capture groups can be called via $+{name}
