As it stands, I don't think your code even compiles, since you've got an unbalanced '(' in your regular expression. I'd start by fixing that.

Second, '|' is a special character in regular expressions, meaning "this OR that". Since you want a literal '|', you need to precede it with a '\'.

Next, you're using '|' again between TOTAL and your digits, while your example has spaces there. Which is it?

'\d' is a character class by itself - it doesn't go in square brackets. But since you also need to match '.', use '0-9.'. Do you also need to match negative numbers? If so, that would be '-0-9.'.

Finally, you're only capturing the first number, and you said you need both.

Putting all of that together, please try this regular expression:

/\|TOTAL\s+([0-9.]+)%\s+([0-9.]+)/
I think that might work better for you....

Test case:

perl -e'$_="~|TOTAL 24.1% 0.4%"; /\|TOTAL\s+([0-9.]+)%\s+([0-9.]+)/ && + print "Matched, $1 $2\n"' Matched, 24.1 0.4
