After a while of click-and-try as well as reading some info at <http://www.w3schools.com/> I think I can manage to do it. There are some issues like the package checks. We use the same element name and depending on the value of some attributes others are required or optional - which is actually quite complex. Anyway I managed to do it and now I can build up my package definitions by mouseclicks in Eclipse. All other XML files will not be that difficult I guess. So stay tuned, I need some more time to complete and test. I found that the XSD files could be a nice source for documentation as well. By using Eclipse (or any other decent XML editor) context-sensitive help and assistance is provided. I put lots of comments and hints inside. So the XSD actually documents every element and value within the packages.xml now. I will do the same for all other XML files too. br, Rainer |
