How to get regular expression to stop at first occurrence and then start searching from there, leading to multiple results

I have a regular expression to search for complete h1 tags (from start of <h1> to end of </h1>) in a content but it searches for the whole content

Regular expression

<h1.*<\/h1>

Content to search for

<h1 style=""></h1><span> alsjd alkj dalsd a</span><h1>asdsadsa</h1>

The result is one match only from first occurrence of starting h1 to last occurrence of ending h1. It matches the whole content.

I want it to give me 2 occurrence of starting and ending h1 tags
like the result should be

<h1 style=""></h1> and 
<h1>asdsadsa</h1>

>Solution :

I think you’ve to make .* non greedy

use this

<h1.*?<\/h1>
