DocBook sounds like you could benefit from it a lot. It's a standardized XML namespace (http://www.docbook.org/) which allows you to use the more popular XSLT stylesheets. AND you can put a customization layer on top of that should you want.
You'll typically transform from XML to TeX and then to any of the 98234098409234 other formats that tex can be exported into.
