Modifier and Type	Method and Description
`void`	`accept(Visitor visitor)` `accept` is the method used in the Visitor Pattern.
`java.lang.String`	`asXML()` `asXML` returns the textual XML representation of this node.
`protected Node`	`createXPathResult(Element parent)`
`java.lang.Object`	`getData()` Accesses the data of this attribute which may implement data typing bindings such as `XML Schema` or `Java Bean` bindings or will return the same value as `Node.getText()`.
`java.lang.String`	`getName()` `getName` returns the name of this node.
`Namespace`	`getNamespace()` Returns the `Namespace` of this element if one exists otherwise null is returned returned.
