Re: Namespace feature using a SAX parser with JAXP.

[Gary L Peskin <ga...@firstech.com>]

Jean-Guillaume --

Yes.  There is a compatability problem here.  The SAX default for
namespace awareness to true while the JAXP default is false, even for a
SAX parser.

Add the line 

  factory.setNamespaceAware(true);

before your call to

  factory.newSAXParser();
