How to highlight-regexp across multiple lines

[Angus Comber]

I was looking at this question on stackoverflow and it seems regex can
select across multiple lines generally but how would I do so for
highlight-regexp in emacs?

Eg I want to highlight ALL text from aPDU... to the final closing brace:

aPDU-rose : retResult : {
  invokeID 2,
  operValue {
    operationValue local : 71,
    result {
      crossRefIdentifier '40 3f'H
    }
  }
}


How would I do that using highlight-regexp?

highlight-regexp aPDU-rose.* hi-yellow  would get me the first line - but
how to get everything including last } character?
