Very good idea ! I have just tested it and it works well. Thank you ! -----Original Message----- From: Michael Glavassevich [mailto:[EMAIL PROTECTED] Sent: lundi 23 avril 2007 20:42 To: j-users@xerces.apache.org Cc: Vila Christophe Subject: Re: Forcing validation without changing XML file
You could try writing a filter which sits in between the parser and the validator that modifies the namespace URIs passed through startElement() and endElement(). Take a look at XMLFilter [1] and XMLFilterImpl [2]. Thanks.
