pretty much anything as far as string parsing goes.

yes. given your intention to learn regexps why not try to come
up with one? if you get stuck show us what you have so far ...
you don't learn to eat with cutlery by being spoonfed.
if you want to parse the whole string in one go you'll want to use
preg_match_all() otherwise use preg_match and iterate over each line ..
foreach(explode("\n", $data) as $line) {
$matches = array();
if (preg_match($line, $regexp, $matches)) {
/* do something */
}
