I have some text with the following structure:

```
Round 1

some multiline text ...

Round 2

some multiline text ...

...

Round N

some multiline text ...

```

I'd like to match rounds with their multiline text.

None of the expressions produces correct result:

(Round\s\d+)((?!Round).\*?)

(Round\s\d+)(.\*?)

Could someone help me?

Thank you in advance.
