Returning/processing XML Form Data and attachments

You can use submitForm() or just about any Acrobat JS DOM function or property, with an XFA form. The AcroForm Doc object is accessible through "event.target". so use "event.target.submitForm". And yes, you can divide up the XFA data model and send parts of it using the "oXML" argument in submitForm().

Attachments are a problem. Not that it can't be done, it's just a rather hairy coding job. The only easy way to send attachements is to send the entire PDF at once. If you want to send them bit by bit you'll need to read out the byte level content with AcroForm "Data" object functions, put it in an XML structure and again send with the "oXML" input to submitForm().

You can track progress with the "app.thermometer" object or with your own Custom Progress bar through code the server sends back in FDF.

Just about every server side programming language has an XML parsing library or use your own. Use whatever you are most comfortable with. It doesn't matter. The XML Acrobat will be sending is pretty basic.
