Working with XML-Schema definitions in Python

Question

Is there any library for python to deal with XML-Schema Definitions (xsd)? I found 'pyxb' and it looks very promising, but development ended in 2018.

Answer 1

The fact that development of a product has ended does not necessarily mean it is dead: it might just be complete and stable.

There is another candidate: Saxon/C. The Enterprise Edition supports XSD processing, and offers a Python API. A disclaimer, however: it is a commercial product produced by my company, Saxonica.

Answer 2

There is XMLSchema which looks very promising, is MIT licensed, currently maintained as at April 2021 and claims:

• Full XSD 1.0 and XSD 1.1 support
• Building of XML schema objects from XSD files
• Validation of XML instances against XSD schemas
• Decoding of XML data into Python data and to JSON
• Encoding of Python data and JSON to XML
• Data decoding and encoding ruled by converter classes
• An XPath based API for finding schema's elements and attributes
• Support of XSD validation modes strict/lax/skip
• Remote attacks protection by default using an XMLParser that forbids entities
• XML data bindings based on DataElement class
• Static code generation with Jinja2 templates
