My approach would be to split the hole text into smaller chunks (with e.g.
explode()) and extract the interesting parts with a regular expression. Maybe
this will give you some ideas:
$chunks = explode("-30-", $mystring);
foreach($chunks as $chunk) {
preg_match_all("/News Releases\n(.+)/s", $chunk, $matches);
var_dump($matches[1]);
}
The regex matches all text between "News Releases" and the end of the chunk.
