You could do a couple of things:

      * Extract all the content and use strip_tags() to remove all the
        HTML markup. In the example you gave it might look a bit odd if
        the content suggests it was originally a list.
      * Access the extracted content through the DOM, and grab the
        textual content you need using node values. That way, you can
        limit it to a specific character count of content, and with a
        bit of work, you can preserve the original markup tags too
