public interface NamespaceResolver

Abstract class that supports lookup of a lexical QName to get the expanded QName.

Method Summary

String	getURIForPrefix(String prefix, boolean useDefault) Get the namespace URI corresponding to a given prefix.
Iterator<String>	iteratePrefixes() Get an iterator over all the prefixes declared in this namespace context.

Method Detail

getURIForPrefix

String getURIForPrefix(String prefix,
                       boolean useDefault)

Get the namespace URI corresponding to a given prefix. Return null if the prefix is not in scope.

Parameters:

prefix - the namespace prefix. May be the zero-length string, indicating that there is no prefix. This indicates either the default namespace or the null namespace, depending on the value of useDefault.

useDefault - true if the default namespace is to be used when the prefix is "". If false, the method returns "" when the prefix is "".

Returns:

the uri for the namespace, or null if the prefix is not in scope. The "null namespace" is represented by the pseudo-URI "".

iteratePrefixes

Iterator<String> iteratePrefixes()

Get an iterator over all the prefixes declared in this namespace context. This will include the default namespace (prefix="") and the XML namespace where appropriate

Returns:

an iterator over all the prefixes for which a namespace binding exists, including the zero-length string to represent the null/absent prefix if it is bound
