Yes, you answered the question correctly. Unfortunately, it was the wrong question. (That's my fault, not yours.)

I should have added: the filename can have _one or more_ digit groups separated by periods in the middle. I want to extract them ALL!

So, for example:


Should yield

0 1 1 2 2 3 3 4 4 5 5 6 6 7 7 8 8 9

I thought the g would do that, but I guess not.

    One way to do it.

    DB<1> $_ = 'ActionLogs.' DB<2> x split ' ', tr/.[a-zA-Z]/ /dr 0 1 1 2 2 3 3 4 4 5 5 6 6 7 7 8 8 9 DB<3>

    Update: The brackets are unnecessary; tr/.a-zA-Z/ /dr works just as well.
