PyXB-CTC 1.3.3rc4

PyXB ("pixbee") is a pure Python package that generates Python source code for classes that correspond to data structures defined by XMLSchema.

PyXB is a pure Python package that generates

Python code for classes that correspond to data structures defined by XMLSchema. In concept it is similar to JAXB for Java and CodeSynthesis XSD for C++.

The major goals of PyXB are:

• Provide a generated Python interface that is “Pythonic”, meaning similar to one that would have been hand-written:

  • Attributes and elements are Python properties, with name conflicts resolved in favor of elements

  • Elements with maxOccurs larger than 1 are stored as Python lists

  • Bindings for type extensions inherit from the binding for the base type

  • Enumeration constraints are exposed as class (constant) variables

• Support bi-directional conversion (document to Python and back)

• Allow easy customization of the generated bindings to provide functionality along with content

• Support all XMLSchema features that are in common use, including:

  • complex content models (nested all/choice/sequence)

  • cross-namespace dependencies

  • include and import directives

  • constraints on simple types
