Method Detail

declarePrefix back to summary

declarePrefix	back to summary
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:String The prefix to declare, or null for the empty string. uri:String The Namespace URI to associate with the prefix. Returns:boolean true if the prefix was legal, false otherwise See Also `getURI`, `getDeclaredPrefixAt`

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:String: The prefix to declare, or null for the empty string.
uri:String: The Namespace URI to associate with the prefix.

Returns:boolean

true if the prefix was legal, false otherwise

public int getDeclaredPrefixCount() Return a count of locally declared prefixes, including the default prefix if bound.

getPrefix back to summary

getPrefix	back to summary
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: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. See Also `getPrefix`

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: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.

getPrefix

getURI	back to summary
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:String The prefix to look up. Returns:String The associated Namespace URI, or null if the prefix is undeclared in this context.

getURI

back to summary

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:String: The prefix to look up.

Returns:String

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

popContext back to summary

popContext	back to summary
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. See Also `pushContext`

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.

See Also: pushContext

pushContext back to summary

pushContext	back to summary
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. See Also `popContext`

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.

See Also: popContext

reset	back to summary
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.
