I suspect what you're looking for is the ability to pipe the XML into
"stdin" of the FOP process. And you'd probably want to be able to send
the PDF to "stdout" afterwards. Unfortunately, this hasn't been
implemented, yet.

You've got about three options:
1. Write a minimal Java class that embeds FOP and does exactly what I
describe above. Shouldn't be hard with information on the FOP website if
you have some Java knowledge.
2. Long-term solution: Add "piping" support to the command-line
interface of FOP and submit a patch.
3. If you want to call FOP many times, for example as part of a server
process, then you'd better deploy FOP as a servlet or web service so you
don't always have the JVM startup overhead each time you create a PDF:
4. You can also experiment attaching FOP to your application using JNI 
(Java Native Interface), but that's a rather hardcore approach.

I hope that gives you some ideas.
