xsdata 21.1

Python XML Binding

Naive XML Bindings for python

---

xsData is a complete XML data binding library for python allowing developers to access and use XML documents as simple objects rather than using DOM.

It ships with a code generator for XML Schema definitions and WSDL 1.1 with SOAP 1.1 bindings. It produces simple dataclasses with type hints in order to reduce the learning curve for users that have to write the binding models manually.

The included xml parser and serializer are highly optimized and adaptable with handlers based on native python and lxml. The parser configuration offers the ability to skip unknown properties and to process xinclude statements.

xsData is constantly tested against the W3C XML Schema 1.1 test suite.

Check the documentation demos or our W3C XML Schema 1.1 test runner and the samples repo for more ✨✨✨
