Make the string as a jquery object, then you can use jquery methods to count the tags.

var findnumberoftags ="<p>hihih</p><h2></h2><li>one</li><li>two</li><p>iam the best</p><h1>yes</h1><h2></h2>";
alert($(findnumberoftags ).filter("h2").length)

Using RegEx for example:

console.log( findnumberoftags.match( /<h2>/g ).length );
