How to use typoscript to strip HTML with the stripHtml function

I use the 'short', or "subheader" field of tt_news as the content of the meta description tag for all of my tt_news articles.

When I first set this up, I was having problems with messy html appearing at the top of some pages. This was a result of some of my articles having some HTML in the short field that wasn't being stripped out.

I found that putting the content of the short through the stripHtml function easily remedies this problem.

Here is the code that I use to strip the HTML from the 'short' field of my tt_news records before using it as the content of the meta description tag.
