WordCount in specific HTML area

Hey, I would like to get the WordCount on an URL, but for a specific HTML tag, e.g. < article >. So I just want to receive the number of words of the article itself, not with all the header and footer links etc.

Is there a way to extend the WordCount formula or any possibility with xpath or csquery?

Thanks!

Not possible using existing SeoTools formulas but you should be able to combine with native Excel formulas, such as:
