[oXygen-user] skip non-xml files when running batch validation

Hi,   I’m running a batch validation process on a directory tree that contains a large number of XML files. However the directory also contains other types of files such as .txt and .log files. These files are showing up in the error log as follows:   System ID: 9703177.log Main validation file: 9703177.logEngine name: oXygen Severity: warning Description: Cannot check file 9703177.log. Unknown extension.   These messages are clogging up my error log. Does anyone know of a way to prevent these messages from appearing in the error log?   Thank you, Scott
