Question

I have following string:

<div> text0 </div> prefix <div> text1 <strong>text2</strong> text3 </div> text4

and want to know wether it contains text3 inside divs that go after prefix:

prefix<div>...text3...</div>

but I don’t know how ta make regex for that, since I can’t use [^<]+ because div’s can contain strong tag inside.

Please help

EDIT:

1. Div tags after prefix are guaranted to be not nested
2. Language is C#
3. Text4 is very long, so regex must not look after closing div

EDIT2: I don’t want to use html parser, it can be easily (and MUCH faster) achieved with Regex. HTML there is simple: no attributes in tags; no nesting div’s. And even some % of wrong answers are acceptable in my case.

Answer 1

this is my new regex:

prefix<div>([^<]*<(?!/div>))*[^<]*text3([^<]*<(?!/div>))*[^<]*</div>

seems to work ok.
