From Adobe InDesign CS2 to InDesign CS5, the ability to work with XML content has been built into every version of InDesign. Some of the useful applications are importing database content into InDesign to create catalog pages, exporting XML that will be useful for subsequent publishing processes, and building chunks of content that can be reused in multiple publications. New coverage includes Export in XML order for EPUB (CS5.5 and later) and some new code examples for that process, perhaps some sample GREP to map content to XML, and strategies and settings for the export to EPUB.
