Naive XML Bindings for python

---

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

The code generator supports XML schemas, DTD, WSDL definitions, XML & JSON documents. It produces simple dataclasses with type hints and simple binding metadata.

The included XML and JSON parser/serializer are highly optimized and adaptable, with multiple handlers and configuration properties.

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

Getting started

$ # Install all dependencies
$ pip install xsdata[cli,lxml,soap]

$ # Generate models
$ xsdata tests/fixtures/primer/order.xsd --package tests.fixtures.primer

>>> from tests.fixtures.primer import PurchaseOrder
>>> from xsdata.formats.dataclass.parsers import XmlParser
>>>
>>> parser = XmlParser()
>>> order = parser.parse("tests/fixtures/primer/sample.xml", PurchaseOrder)
>>> order.bill_to
