I've been on vacation, but I didn't see any comments. My first reaction
when I saw the caching in the code was that it was an optimization that
benefits some usage patterns but not others. In my case, getText would be
called only once on most of the elements anyways. And I'm not keeping the
text around as text in most cases, so the caching would be more like a
memory leak (albeit a bounded one)...
