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 that don’t depend on the library itself 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 ✨✨✨

Updated field xml type auto detection to be more flexible. #246
Updated EnumConverter to resort to canonical form matching as last resort. #273
Updated support for derived elements. #267
This is my favorite release so far, maybe because xsdata reached one year of development ✨✨✨ or maybe because some of the last original components finally got the rewrite they deserved.
Why naive?
The W3C XML Schema offers so much flexibility and abstraction layers and grammatical rules to support practically any xml document definition.
Integration teams and clients don’t care about any of that, take out abstraction and flexibility and you are left with lean named data structures with typed attributes and a namespace for humans to read!
