For any reasonably complex data set, you need multiple views to navigate it. Take a QA test system, for example: With a pool of tests and test results, you need to see the data by date, by test category, by individual test, and so on. Each view would be in its own HTML file. So, can you have a single template in XSLT 2.0 build multiple HTML files from the one input data set?
A common problem with XSLT is that it takes only a single XML file as input. You can use a cross-platform Java™ tool to create an XML directory listing, then use XSLT to process every file in the directory from that listing. This tip covers installation and use of such a tool, as well as the corresponding XSL that processes multiple files from the directory listing.
