RegEx - Match only when a certain word occurs

Question

Its probably super simple.

I want to match only where a certain word exists in between full <headers>

This is what i have so far.

(<h[d{1-6}](.itemprop.)(.*?)</h[d{1-6}]>)

I want it to match

<h1 class="test" itemprop="name">Test</h1>

AND

<h2 itemprop="name" class="test">Test</h2>

AND

<h6 class="test"><strong itemprop="Price">9,99</strong>Test</h6>

As it is now it only matches <h{1-6} itemprop etc

Answer 1

How about:

<h([1-6]).*?\bitemprop\b.*?</h\1>)
