I've uploaded a BETA (actually more like an Alpha) script that can read and write (most) Action files as well as read the runtime Action palette here.
It does fail on some actions. Fixing this is in the queue along with:
finishing the Action Palette support. This includes (1)doing a full read on Actions instead of just reading the header. (2)reading and writing Action Palette (.psp) files improving overall performance conforming more to Adobe's object model (using 'typename' attributes, etc...) docs (of course) lots more testing PSCS and PS7 support
I have an XML kit for all of this about 90% done at this point. I'll drop that out after I get a better testing regime in place and fill in some of the blanks.
Let me what problems you may come across. I should be ready for another release in a week or so and would like to get some more people looking at the code and running it.
Thanks ahead of time for your help.
And many thanks to Tom Ruark and Bob Stucky for needed technical support.
