Is there an equivalent for "index" that uses regular expressions instead of exact string?
I've been looking at index, pos, m//, and the corresponding "$" variables but nothing I've found so far does what I'm looking for. Specifically, what I'm trying to do is find all the starting locations of a RE match. For example, using an exact string match:
$ perl -e '$foo="baaaab"; $re="aa" ;
for ($bar=index($foo, $re); $bar >= 0 ; $bar=index($foo, $re, $bar+1))
{ print $bar, "\t" }
print "\n" ; '
1 2 3
I'd like to do the same except use a regular expression. BTW, notice that matches can overlap.
Any thoughts or ideas?
