Not possible. > b) Extend one of Cocoon's generator classes (StreamGenerator?) to handle > the multi-part form data and call it from my form. Way to go. Yes, StreamGenerator. > c) Is there a way to modify the File Upload example to hand the upcoming > stream to a transformation? It seems that example merely specifies a > directory for uploads and does nothing with the stream itself. It has different purpose; it supposed usage is to upload binary resources, not the XML which requires further processing. Vadim > d) ? > > What is the cleanest manner of doing this?
