public void addElementNamespaces(Navigator nav,

                          throws UnsupportedAxisException

Parameters:

nav - the navigator for use in conjunction with element

element - the element to copy the namespaces from

Throws:

UnsupportedAxisException

translateNamespacePrefixToUri

public String translateNamespacePrefixToUri(String prefix)

Description copied from interface: NamespaceContext

Translate the provided namespace prefix into the matching bound namespace URI.

In XPath, there is no such thing as a 'default namespace'. The empty prefix always resolves to the empty namespace URI.

Specified by:

translateNamespacePrefixToUri in interface NamespaceContext

Parameters:

prefix - The namespace prefix to resolve.

Returns:

The namespace URI matching the prefix.
