What Python accessible tools can you use to generate XSD from an XML document?

Question

I'm looking for a tool that will play nicely with Python. Except for my Python requirement, my question is the same as this one:

"I am looking for a tool which will take an XML instance document and output a corresponding XSD schema."

Answer 1

According to the PyCharm docs, PyCharm has a facility for this. This is not exactly accessible by a program as an API. You are probably better off using XML Schema Learner as a separate program since it is a command line program (subprocess friendly!).

Answer 2

Are you looking for something like pyxsd? (primarily used for validation against a schema) Or maybe PyXB? (can generate classes based on xml) Otherwise, I don't think there's a tool [yet] that will generate the schema from within Python. Can you do it on demand using something like xsd.exe? Does it have to be programmatic/repeatable?

Answer 3

Currently, there is no module that will run within your python program and do this conversion. But I see the problem of creating a XSD schema from XML as a tooling problem. It's the kind of functionality that I'll use once, to get a schema started but after that I'll be maintaining the schema myself. From reading a single XML file the XSD generator will create a starting point for a real schema, it cannot infer all the functionality and options offered by XSD. Basically, I don't see the need to have this conversion run as a module inside of my code, generating new XSDs every time the XML changes. After all, it's the schema that defines the XML not the other way around.

As end-user pointed out you could use xsd.exe but you might also want to look at other tools such as trang (a bit old) for Java and stylusstudio (XML tool).
