NamespaceContext
This method looks up the prefix in the current context. If no mapping is found, this methods will continue lookup in the parent context(s). Use the empty string ("") for the default Namespace.
getURI
in interface NamespaceContext
prefix
- The prefix to look up.
public java.lang.String getPrefix(java.lang.String uri)
NamespaceContext
This method looks up the namespace URI in the current context. If more than one prefix is currently mapped to the same URI, this method will make an arbitrary selection If no mapping is found, this methods will continue lookup in the parent context(s).
getPrefix
in interface NamespaceContext
uri
- The namespace URI to look up.

public void pushContext()
NamespaceContext
A new context should be pushed at the beginning of each XML element: the new context will automatically inherit the declarations of its parent context, but it will also keep track of which declarations were made within this context.
pushContext
in interface NamespaceContext
NamespaceContext.popContext()
public void popContext()
NamespaceContext
The context should be popped at the end of each XML element. After popping the context, all Namespace prefix mappings that were previously in force are restored.
Users must not attempt to declare additional Namespace prefixes after popping a context, unless you push another context first.
popContext
in interface NamespaceContext
NamespaceContext.pushContext()
public boolean declarePrefix(java.lang.String prefix, java.lang.String uri)
NamespaceContext
This method declares a prefix in the current Namespace context; the prefix will remain in force until this context is popped, unless it is shadowed in a descendant context.
Note that to declare a default Namespace, use the empty string. The prefixes "xml" and "xmlns" can't be rebound.
Note that you must not declare a prefix after you've pushed and popped another Namespace.
declarePrefix
in interface NamespaceContext
prefix
- The prefix to declare, or null for the empty
string.uri
- The Namespace URI to associate with the prefix.

NamespaceContext
It is necessary to invoke this method before reusing the Namespace support object for a new session.
Note that implementations of this method need to ensure that the declaration of the prefixes "xmlns" and "xml" are available.
