You can skip the array assignment and just do:
foreach ( split "\n", $scalar ) {
...
}
I predict a reply that uses map()... though I think that using a map
isn't really another solution, but just an alternative to the for
loop.
map {stuff}, split "\n", $scalar;
But I think the answer is basically as you said. Use split.
Then again, you ought to be able to open a pipe and print the scalar
to the pipe and use the:
while <HANDLE>
syntax. I'm not sure how exactly the newlines would get treated in
that scenario...
