public interface NamespaceResolver

Abstract class that supports lookup of a lexical QName to get the expanded QName. This extends the JAXP NamespaceContext interface with some Saxon-specific methods, which must be supplied in a concrete implementation.


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

Method Detail

getURIForPrefix

java.lang.String getURIForPrefix(java.lang.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

java.util.Iterator 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
