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.
Generate data models from XML Schema 1.0 and 1.1 definitions.
Supports qualified elements/attributes.
Supports enumerations and inner classes.
Flattening strategies to keep the code as simple as possible.
Preserve embedded documentation and references
Pluggable code writer that supports different formats

Changelog: 20.5.5 (2020-05-23)¶
Added version option in the xsdata cli.
Added generation of missing python __init__ files.
Added support for default values to inner enum classes.
Fixed multiple issues with abstract classes and attributes/extension flattening.
Fixed instance cross references causing codegen unpredictable results.
Fixed xml serialization of wildcard attributes with user defined model values.
Fixed issue with redefined/override elements with annotations.
Fixed expand attribute groups recursively.
Fixed false positive circular references.
Fixed enumeration unions detection.
Refactored ClassAnalyzer to smaller components.
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!
