    public interface NamespaceResolver

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

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
