: Im searching for a library - free or commercial - which gives me the possibility to transform files (e.g. ini, csv, ...) to XML by the use of schema files.
: My aim is to develop a program in c# which has to transform XML data to csv, ini, ... files and vice versa. I think .NET gives me a good possibility to transform XML to what ever using XSL, but what about the way back. Therefore Im searching for a library giving me that possibility. As the source files which have to be transformed have different structure/look the use of schema files are a must.
If by "schema file" you mean XML Schema then there isn't any such thing. XMLSchema describes XML documents. ini and csv files are not XML documents.
A big problem you're going to have is that XML includes a lot more information about the data (meta-information) than a csv file contains. A ini file has a bit of meta information in it, but it's still not structured like XML is. And at any rate, XMLSchema only describe document structures, they don't create them.
I think you'd be better off looking for libraries that parse the various kinds of files and write simple programs yourself to convert the data to XML. Then you can validate against a schema if you want to.
