Answer 1

JSON is a nested structure, which regular expressions aren't well-suited to parse. If you know that the key you're looking for won't have any objects inside it, then you could match up until the first close brace after the key, with a regex like this:

"PI":.*?}

Note that this is not resilient at all if there's weird stuff in your json, but if you're confident that the structure is always going to be simple enough then it should work.
