I had to complete a project that involved working with a web service. Problem was, I had the XML files, but needed the XML Schema Definition (XSD) schemas, and coming up with them manually would have been too tedious and would have took too much time. So I went online, and found 2 reliable methods. Oh, and they are free!
Generate XSD from XML Tool
Using it is simple: Just extract it, then go to your command-line, and run it against any XML document that you may have. Trang is written in Java, so it’s cross-platform and compatible with any platform that can run the Java Virtual Machine. To use it, just use it in this syntax:
trang.jar <your XML> <your desired XSD>
trang.jar YourDocument.xml YourSchema.xsd
Viola! You’ll find your XSD automatically generated!
Generate XSD from XML Online
If you don’t want to go through Trang, you can use an online tool. The only online XML to XSD tool that I found was this one: Generate XSD from XML Online
It’s pretty good too, and can give you a quick XSD from your XML document.
