So how would I find the last 'a' before the first 'foo'?
My latest attempt is:
$tmp = 'abcdefgabcdefgfooabcdefgfoo'; $tmp =~ m/(foo)/ogcs; [do stuff with $1] # this part works as I'd hoped $tmp = substr($tmp, 0, pos($tmp)); $tmp =~ m/.*(a).+?$/os;
But that still got the first 'a'. Also, $tmp
can be
rather large so the substr is a bit distasteful.
Is there any way to search backward from the current
pos()
or something similar?
