RegEx - match specific html tags between other tag

Question

I′ve got a problem that I have to remove all HTML br tags in an unordered list. The input HTML looks like this

<br /><ul><br /><li>one</li><br /><li>two</li><br /></ul><br />

Now I have to remove the br tags in the unordered list (and not the ones before and following)

I tried to solve the problem via regular expressions

(?<=(<ul.*>))(.*)(?=(</ul>))

That gives me the text between the ul tags.

But how can I get only the br tags in the selection?

Thank you very much in advance!

The solution from Wiktor Stribizew (see above) is working

/(?<=<ul[^>]*>.*?)<br />(?=.*?</ul>)/g
