Hi Didier, > <question> > Why do you convert the hierarchical database into XML? Is it > because the > hierarchical database do not have a DOM interface? > </Question> Not quite sure what you mean. Do you mean, why did we go via XML before we transformed with XSL? Or do you mean, why is there a separation between the DOM and the database? I'll tell you what we're currently doing and see if it helps. The hierarchical database is just good old SQL Server at root, with a few layers on top, so there is no tight integration between a DOM and the database. In the version you're seeing we actually make the tags by string concatenation! It was all written 8 months ago, so go easy on us. In the newer (unreleased) version we read the data from the database and use it to populate a DOM tree, and then either transform it with XSL and export the result, or just pass it through. So if your question is the first - why go out to XML before bringing it back in again to transform with XSL - then it's just because it's old code and the new code does go straight into a DOM. On the other hand, if you're implying that we just treat the database as one big DOM and transform the nodes we want out, then I have to ask, has anyone done that? Are there actually any databases out there that hide behind a DOM interface and present themselves as one big tree of nodes? I've done just that at the level of treating a web server as a great big node store and using XQL to dig out 'documents' - that's how the next release of the magazine will work - but it would be really interesting if the DOM/DB integration has been developed further.
