xsdata 21.4

Python XML Binding

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.

It ships with a code generator for XML schemas, WSDL definitions and XML documents. It produces simple dataclasses with type hints and 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

>>> # Parse XML
>>> from pathlib import Path
>>> from tests.fixtures.primer import PurchaseOrder
>>> from xsdata.formats.dataclass.parsers import XmlParser
>>>
>>> xml_string = Path("tests/fixtures/primer/order.xml").read_text()
>>> parser = XmlParser()
>>> order = parser.from_string(xml_string, PurchaseOrder)
>>> order.bill_to
