Class NamespaceIterator

java.lang.Object

net.sf.saxon.tree.util.NamespaceIterator

All Implemented Interfaces:

java.util.Iterator<NamespaceBinding>

public class NamespaceIterator
extends java.lang.Object
implements java.util.Iterator<NamespaceBinding>

This class provides an iterator over the namespace codes representing the in-scope namespaces of any node. It relies on nodes to implement the method NodeInfo.getDeclaredNamespaces(net.sf.saxon.om.NamespaceBinding[]).

The result does not include the XML namespace.

Method Detail

iterateNamespaces

public static java.util.Iterator<NamespaceBinding> iterateNamespaces(NodeInfo element)

Factory method: create an iterator over the in-scope namespace codes for an element

Parameters:

element - the element (or other node) whose in-scope namespaces are required. If this is not an element, the result will be an empty iterator

Returns:

an iterator over the namespace codes. A namespace code is an integer that represents a prefix-uri binding; the prefix and URI can be obtained by reference to the name pool. This iterator will represent all the in-scope namespaces, without duplicates, and respecting namespace undeclarations. It does not include the XML namespace.

sendNamespaces

public static void sendNamespaces(NodeInfo element,
                                  Receiver receiver)
                           throws XPathException

Send all the in-scope namespaces for a node (except the XML namespace) to a specified receiver

Parameters:

element - the element in question (the method does nothing if this is not an element)

receiver - the receiver to which the namespaces are notified

Throws:

XPathException - if a failure is reported by the downstream Receiver
