How to write non-XML data to a file using an OSB FTP Routing?

Question

Hi --
Situation ... I need to write non-XML data to a file using FTP. A proxy service retrieves XML and transforms it with XSLT to CSV format, then gives it to a Biz service to file it out, using FTP. Simple.
Problem ... OSB sends the contents of $body to any service it calls. Because $body is a SOAP document, it has to contain XML. So therefore I have to put my CSV data into an XML element, in order to put it into $body; and this inner element then gets written to the file, which I don’t want. But if I don't enclose my CSV content in a tag, I get "Unexpected CDATA encountered" trying to assign it to a variable.
There has to be away around this!
Thanks for your help.

Solved. Steps:
-- Transform the XML to CSV using an XSL transform. Put the CSV data inside enclosing XML elements, and use a Replace action to put the XML element + CSV contents back into *$body*.
-- Define an MFL transform that only knows about the enclosing XML elements. Use a delimiter of "\n" (hard return).
-- Route from the proxy service to a Biz service that has Service Type = Messaging Service and Request Message Type = MFL; specify the MFL transform, which will receive the incoming *$body* variable, strip off the enclosing XML element within it, and pass the CSV contents to the FTP service.
