      xml-config:

      <int:chain input-channel="channel.read.file" output-channel="channel.process.input">
    <int-file:splitter markers="true"/>
    <int:filter expression="!(payload instanceof T(org.springframework.integration.file.splitter.FileSplitter.FileMarker))"
            discard-channel="channel.process.file.marker"/>
