Public Methods

public boolean declarePrefix (String prefix, String uri)

Declare a Namespace prefix.

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.

Parameters
prefix The prefix to declare, or null for the empty string.
uri The Namespace URI to associate with the prefix.
Returns
  • true if the prefix was legal, false otherwise

public Enumeration getAllPrefixes ()

Return an enumeration of all prefixes whose declarations are active in the current context. This includes declarations from parent contexts that have not been overridden.

Returns
  • Enumeration

public String getDeclaredPrefixAt (int index)

Returns the prefix at the specified index in the current context.

public int getDeclaredPrefixCount ()

Return a count of locally declared prefixes, including the default prefix if bound.

public List getDeclaredPrefixes ()

public NamespaceContext getNamespaceContext ()

public String getPrefix (String uri)

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 The namespace URI to look up.
Returns
  • One of the associated prefixes, or null if the uri does not map to any prefix.

public SymbolTable getSymbolTable ()

public String getURI (String 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 The prefix to look up.
Returns
  • The associated Namespace URI, or null if the prefix is undeclared in this context.

public void popContext ()

Revert to the previous Namespace context.

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.

public void pushContext ()

Start a new Namespace context.

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.

public void reset ()

Reset this Namespace support object for reuse.

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.
