the specified URI. The xml
prefix is also bound to the URI
http://www.w3.org/XML/1998/namespace
.
prefix

- the namespace URI the prefix is bound to
addNamespace
public void addNamespace(String prefix,
String uri)
Binds the specified prefix to the specified namespace URI.
If the prefix is already bound in this context, the new URI
replaces the old URI. Binding a prefix to null removes the
declaration. The binding of the xml
prefix
may not be changed.

- the namespace URI the prefix is bound to
makeNamespaceContext
public static XPathContext makeNamespaceContext(Element element)
Creates a new XPath context that contains all the namespace
bindings in scope on the element. Changing
the prefixes in scope on the element after the context
is returned does not change the context.
element
- the element whose namespace bindings are copied
- all the namespace prefix mappings
in scope on the element
