Hi Paulo,
I'm not an expert in HL7 XML encoding syntax, but I just checked and the
latest version of the spec that I have a copy of shows HAPI's current
behaviour as being correct. It says "The message structure ID is used as a
root element for the XML instance documents."
This may have changed though, as the document I have (HL7 Version 2: XML
Encoding Syntax Release 1) is dated from June 2003. Do you (or anyone on
the list) know differently?
All of that said, it would probably be possible to implement that behaviour
you describe by subclassing DefaultXMLParser and then overriding
encodeDocument(String)<http://hl7api.sourceforge.net/xref/ca/uhn/hl7v2/parser/DefaultXMLParser.html#97>so
that it calls the super implementation and then modifies the name of
the
root element that is returned.
If by chance you do this and want to contribute it as an example for the
HAPI documentation, that would be awesome!
Cheers,
James
