It happens in the "clean" doctests, in one of the ".xpath()" method calls. One
thing to try might be using XPath() instead. However, looking at the way
clean() is implemented, I would rather rewrite a few places to use the already
existing loop over getiterator() rather than XPath. Most likely, users will
end up requiring the loop to run anyway, so it would be best to use it for
more rather than additionally parsing and running a C loop on different XPath
expressions.
