AEGP / EggP? Parse aep file or use SDK?

I am trying get all of the text layers (their text) out of an After Effects Project (7.0). I have the 7.0 SDK and I see how I might access a selected layer, but I don't see how I can get All of the text layers. So this put me onto just parsing the .aep file and seeing if I could just grab all the TextObjects from within it.

It appears that a .aep is encoded as a .eggP,(Assuming that is where we get: AEGP).

Anyway could anyone point me in the right direction.. Maybe the SDK can get all Text Objects's Text, if not how might I go about parsing the .aep file to grab them?

In the meantime I have written an after effects script that will extract all of the text layers.. Perhaps that is as good as it gets. Figured I would ask anyway.

Thanks!
