Output text content from blog summary without HTML/CSS styling

On my blog listing pages I have the summary shown, but some posts have large <h2> elements at the top, which look funny on the listing page. Is there a way to unstyle the post_summary field?

Relevant code:

<div class="post-preview">
 {{ rec_post.post_summary|truncatehtml(100) }}
</div>

Never mind, I have solved my own problem. There is the “striptags” filter that will do this.

{{ rec_post.post_summary|striptags|truncatehtml(100) }}
