Duh. I had NodeRefList.hpp in the includes section and XalanNodeList in
the XALAN_USING_XALAN() stuff. Getting kinda bleary eyed and missed the
disconnect.

It didn't look right but I wanted to exhaust other possibilities before
coming back to the well again.

Thanks Dave, that was going to be my next attempt. The getChildNodes()
looked really convenient for what I wanted to do, but I was getting to
the point where I was ready to punt on this and do the getFirst...,
getNext... thing. I'm working strictly in the Xalan world so the
getChildNodes() method won't work anyway. Thanks very much for all your
help today.
