...

i am looking for a regular expression which extracts a group of number from the end of a line like the following:

"This line may contain digits (9) but ends with numbers like 1 2 3 4 5"

When using a regex like "^(.+)(\\s+(\\d+))+$" I receive "This line may contain digits (9) but ends with numbers like 1 2 3 4" and "5".

Can someone help me?

What about: "^(.+)[^\\d\\s](\\s+\\d+)+$"

HTH, John.

Hi John,

sorry, but this gives also only the last number.

If you want the group, not the each number separately, this should work: ^.*[^ 0-9] *([ 0-9]+)$ Testing with perl: perl -e '$x = "This line may contain digits (9) but ends with numbers like 1 2 3 4 5"; $x =~ s/^.*[^ 0-9] *([ 0-9]+)$/$1/g; print "$x\n";' Output: 1 2 3 4 5 Regards, Roland
