How to exclude headings inside of an ordered list from toc generation?

[dbzx10299]

If we have a blog page with a table of contents, is there a way that we can exclude headings if they are in a <ol> for example?

Say we have the following code, how can we exclude the h3 headings inside of the ordered list?

<h2>Setup</h2>
<h3></h3>

<h2>Tutorial</h2>

<ol class="tutorial">
  <li>
    <h3>Step 1</h3>
  </li>
  <li>
    <h3>Step 2</h3>
  </li>
</ol>
