This implementation of NamespaceContext has the ability to maintain multiple scopes of namespace/prefix bindings. This is useful in situations when it is not always appropriate for elements to inherit the namespace bindings of their ancestors (such as included elements in XInclude). When searching for a URI to match a prefix, or a prefix to match a URI, it is searched for in the current context, then the ancestors of the current context, up to the beginning of the current scope. Other scopes are not searched.

Look up a namespace URI and get one of the mapped prefix.

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).

Parameters
uri:String

The namespace URI to look up.

Returns:String

One of the associated prefixes, or null if the uri does not map to any prefix.

Look up a prefix and get the currently-mapped Namespace URI.

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.

Parameters
prefix:String

The prefix to look up.

Returns:String

The associated Namespace URI, or null if the prefix is undeclared in this context.

public void popScope()

Pops the current scope. The namespace bindings from the new current scope are then used for searching for namespaces and prefixes.

pushScopeback to summary
public void pushScope()

Begins a new scope. None of the previous namespace bindings will be used, until the new scope is popped with popScope()

public void reset()

Overrides org.apache.xerces.util.NamespaceSupport.reset.

Implements org.apache.xerces.xni.NamespaceContext.reset.

Only resets the current scope -- all namespaces defined in lower scopes remain valid after a call to reset.
