Interface XmlElement

All Superinterfaces:

Cloneable, XmlContained, XmlContainer

All Known Implementing Classes:

XmlElementAdapter, XmlElementImpl

public interface XmlElement
extends XmlContainer, XmlContained, Cloneable

Represents Element Information Item except for in-scope namespaces that can be reconstructed by visiting this element parent, checking its namespaces, then grandparent and so on. For convenience there are methods to resolve namespace prefix for given namespace name.
NOTE: this representaiton is optimized for streaming - iterator approach that allows gradual visiting of nodes is preferred over indexed access.
