OK I'm done ! This is working. Thank you for you help. -----Original Message----- From: Michael Glavassevich [mailto:[EMAIL PROTECTED] Sent: mardi 24 avril 2007 19:11 To: j-users@xerces.apache.org Cc: Vila Christophe Subject: RE: Forcing validation without changing XML file
You can't put your SAX filter ahead of anything inside of the XMLReader. The validator I meant was a JAXP Validator [1] or ValidatorHandler [2] not the integrated one in the parser. XMLReader -> XMLFilter (your filter) -> Validator / ValidatorHandler Thanks.
