public final class TreeWalker extends java.lang.Object
This class does a pre-order walk of the DOM tree, calling a ContentHandler interface as it goes. This class is a copy of the one in org.apache.xml.utils. It exists to cut the serializers dependancy on that package.

public org.xml.sax.ContentHandler getContentHandler()
Get the ContentHandler used for the tree walk.- Returns:
- the ContentHandler used for the tree walk
-
traverse
public void traverse(org.w3c.dom.Node pos) throws org.xml.sax.SAXException
Perform a pre-order traversal non-recursive style. Note that TreeWalker assumes that the subtree is intended to represent a complete (though not necessarily well-formed) document and, during a traversal, startDocument and endDocument will always be issued to the SAX listener.- Parameters:
pos
- Node in the tree where to start traversal- Throws:
TransformerException
org.xml.sax.SAXException
