Examples of nu.xom.Element

nu.xom.Element
This class represents an XML element. Each element has the following properties:
- Local name
- Prefix (which may be null or the empty string)
- Namespace URI (which may be null or the empty string)
- A list of attributes
- A list of namespace declarations for this element (not including those inherited from its parent)
- A list of child nodes
