I remember leveraging xml and xslt for doing the exact thing for my resume! This was quite some time ago, when xml was king. So, as a way to both unify my generation for my resume but more importantly learn more about xml, xslt, i created what sounds like a similar pipeline to yours. It felt really cool, and i learned about xslt - which to this day i'm impressed by. But, over the years as xml, xslt seem to have waned, plus i never got to use such skills at any of my jobs, and finally employers just wanted a Word doc, not a PDF...then i just stopped using my setup. Nowadays i simply keep a local copy of an .ODT file, and export to word or PDF, or whatever format an employer or recruiter asks for...and like 99.999% of the time its a Word doc. But, back then, it certainly as fun learning that stuff!
