@SAMSAL @ChuckE , I believe parsing the schema for each flowfile that goes through the processor would be too expensive. Because of that, the schema is parsed only once when the processor is scheduled and used for every flowfile. That's why the attribute values cannot be used for this property. Having a schema hashmap<filename, parsed_schema> internally could be an interesting idea so that the processor would parse the schema onTrigger only once for every schema file name and reuse it afterwards. Obviously memory usage could be a problem if you have too many schemas, but I don't think this is likely to happen. This doesn't happen currently, but it would be a nice feature request IMO. Currently, you can either do that with a scripting processing or use RouteOnAttribute to send each message to a ValidateXML processor with the correct schema. Cheers, André
