Examples of DTMTreeWalker

org.apache.xml.dtm.ref.DTMTreeWalker
This class does a pre-order walk of the DTM tree, calling a ContentHandler interface as it goes. As such, it's more like the Visitor design pattern than like the DOM's TreeWalker. I think normally this class should not be needed, because of DTM#dispatchToEvents.
