This interface allows an application to tell a transformer how to resolve the URIs that appear in an XSLT stylesheet. If you pass a URIResolver to the setURIResolver( ) method of a TRansformer or transformerFactory then when the transformer or TRansformerFactory encounters a URI, it first passes that URI, along with the base URI to the resolve( ) method of the URIResolver. If resolve( ) returns a Source object, then the transformer will use that Source. If a transformer or transformerFactory has no URIResolver registered, or if the resolve( ) method returns null, then the tranformer or factory will attempt to resolve the URI itself.

// Public Instance Methods
     Source resolve(String href, String base) throws TransformerException;
