List item with a span inside

[ruudbwai]

I have list items with spans in them, and I'd like to strip the spans out before the list item is returned by selectnav, how do I go about this? eg

<li><a href="somelink.html">Chapter Here <span>description here</span></a></li>

selectnav returns the list item as Chapter Heredescriptionhere but I want to remove that description span.

Hope that makes sense.

Thanks.
