This blog post has shown two approaches using different versions of classes with nameJsonSchemaprovided by Jackson to write JSON based on Java classes generated from an XSD with JAXB'sxjc. In order to use the library, you have to reference the assembly file XsdToJsonSchema.dll from your .NET project and the assembly DLL must be deployed with your application. No but easy enough to do. This implementation is not complete, e.g., it doesn't cleanly support cases where an element has both text and attributes, or both text and children (only because I didn't need it when I wrote it) It should be easy to improve it, though. Here's a newer, simple code to do this conversion. xsd2json is that tool. Note the following when using XML as source. For convenience, I have reproduced that simple schema here without the XML comments specific to that earlier blog post: It is easy to use the xjc command line tool provided by the JDK-provided JAXB implementation to generate Java classes corresponding to this XSD. Given that, I now look at using the new preferred approach (Jackson JSON Schema Moduleapproach). Which leads me to the approach I found best for this case: parsing the xml using lxml, and then wrapping the etree nodes (lazily), providing them with a dict-like interface. It takes time to get right and you may even write tools to help you with generating some of it, but it would look roughly like this: You may want to have a look at http://designtheory.org/library/extrep/designdb-1.0.pdf. XML Schema (XSD) Options. Let us consider this sample XML file: Here is a sample program on how we can include XML namespaces in the JSON format as well: ALthough converting from XML to JSON is the prime objective of this module, xmltodict also supports doing the reverse operation, converting JSON to XML form.
