Examples of nu.xom.Namespace

nu.xom.Namespace

Represents a namespace in scope. It is used by XOM's XPath implementation for the namespace axis. However, it is not really part of the XOM data model. Namespace objects are only created as needed when evaluating XPath. While a namespace node has a parent element (which may be null), that element does not know about these namespace nodes and cannot remove them. (This is an inconsistency in the XPath data model, and is shared with attributes which also have parents but are not children.)
