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
