Hi, We''ve recently had a breakthrough in XML-izing a file format at work (after years of attempts) and are still reeling with the prospects that this opens. The files are templates for book publishing and contain all of the specs (margins, fonts, sizes) in about 7 (up to ~12) levels of nesting. They''re usually ~100k lines. The first project I''d like to attempt (with Rails) is to create a web-based interface for viewing and editing formats (maybe a bunch of elements in a bunch of styles at once). I feel like I understand most of how I''ll implement this Rails interface with XML but was hoping to find a few articles/blogs about how other (smarter) people are solving this sort of problem. However, I''ve been struggling to find stuff. Anyone got suggestions on where to do some reading? Thanks, Keith
