Examples of nu.xom.Node

nu.xom.Node
The generic superclass for all the contents of an XML document. There are exactly eight kinds of nodes in XOM:
- Element
- Document
- Text
- Comment
- Attribute
- ProcessingInstruction
- DocType
- Namespace
Every instance of Node is an instance of one of these eight classes (including, possibly, one of their subclasses).
