XML : How to create ISO8583 Meesage from XML using j583

Using http://j8583.sourceforge.net/ I have parsed ISO message to XML in Java.

ISO to XML:

   <j8583config>   <parse>    <PROCESSINGCODE>000000</PROCESSINGCODE>     <SYSTEMTRACEAUDITNUMBER>000001</SYSTEMTRACEAUDITNUMBER>     <Cardacceptorterminalidentification>3239313130303031</Cardacceptorterminalidentification>     <Reservednational>001054455354204D45535347</Reservednational>     <Networkmanagementinformationcode>0301</Networkmanagementinformationcode>     </parse>    </j8583config>    

Now I need to do vice-versa. I need to create ISO message from XML.

Can someone please guide for this.

Any help is appreciated.
