Ok, I did successfully accomplished it.

It took me a while to figure how to do it. I haven't found any direct way in WWC to do it. So, I did it manually.

FUNCTION ToXML
LOCAL lcHtml,lcHeader
lcHeader=''
lcHeader=lcHeader+'HTTP/1.0 200 OK'+CHR(10)
lcHeader=lcHeader+'Content-type: text/xml'+CHR(10)
lcHeader=lcHeader+'Expires: -1'+CHR(10)
lcHeader=lcHeader+CHR(10)
CURSORTOXML(ALIAS(),'lcHtml',1,48,0,'')
lcHtml=lcHeader+lcHtml
RETURN lcHtml
