Writing C with XML and XSLT

I've been playing with writing C code with XML and XSLT. I have been using this to look at a state machine where each state is a separate C function. eg the BSD Installer C backend.

The basic gist is:

<installer>
 <window name="foo">
  <button name="b1"/>
  <button name="b2"/>
 </window>
 <window name="bar">
  <button name="baz">
 </window>
</installer>

The XSL file then converts each <window> to a separate function with each <button> becoming the correct definition for a button in dfui API.
