Extract report in SAP PI 7.31 Single stack

Hello experts,

      I have a strange question. In PI 7.31 Java Only do we have an option to extract report on daily/weekly basis. Say, if a proxy to file is processed. PI would have that payload xml file. From that payload file we need to get some fields and generate a log file with that particular fields and values in it and send it as attachment someone's email id.

     This question is strange but please give your valuable inputs. Waiting for your reply gurus.

Thanks

Ravi.
