How to get encoding declaration from

Hi,

How do you get the encoding=xxx declaration from the <?xml ...?>
declaration of an xml document using Xerces? I'd like to use SAX to do
it, but I don't see an interface that that has a getEncoding() method so
far that works off the xml document.

Additionally the DefaultHandler::startPrefixMapping() method has a note
in the documentation that says, "The current Implementation of
SAX2Parser will _NEVER_ call this".  So is there some other built in way
to get the prefix mappings?

Thanks for any help here,

Hi Elisha,
you can try installing an "advanced document handler" using 
installAdvDocHandler(); in your XMLDocumentHandler-derived class, you 
will receive the <?xml... declaratin through the XMLDecl method

     virtual void XMLDecl
     (
         const   XMLCh* const    versionStr
         , const XMLCh* const    encodingStr
         , const XMLCh* const    standaloneStr
         , const XMLCh* const    autoEncodingStr
     )

As for the startPrefixMapping documentation, it was outdated: the 
parser does indeed call it.
