xsdata 20.5.5

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.

xsData comes with a code generator that can convert XML Schema 1.0 and 1.1 definitions to simple dataclasses with type hints and as minimum footprint as possible. The generated packages have no dependency on the library itself. So simple that you can write the models on your own if you happen to use an XML document with no schema available.

The XML Parser is highly optimized and uses lxml iterparse to bind the document data to the target models. The parser accepts a configuration instance with various options like fail on unknown properties and is also thread safe which means you can take advantage of the internal model inspection caching context for even faster parsing.

The parser and serializer are constantly tested against the W3C XML Schema 1.1 test suite and passes more than 99% of the valid instance cases.

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