Method Details

[hide private]

init(self, *args, **kw)
(Constructor)

source code

Create a new Namespace.

The URI must be non-None, and must not already be assigned to a Namespace instance. See NamespaceForURI().

User-created Namespace instances may also provide a description.

Users should never provide a builtin_namespace parameter.

Overrides: object.__init__: (inherited documentation)

ProcessTypeAttribute(self, value=None)

source code

Specify how PyXB should interpret xsi:type attributes when converting a document to a binding instance.

The default value is PT_strict.

xsi:type should only be provided when using an abstract class, or a concrete class that happens to be the same as the xsi:type value, or when accepting a wildcard that has an unrecognized element name. In practice, web services tend to set it on nodes just to inform their lax-processing clients how to interpret the value.

Parameters:

value - One of PT_strict, PT_lax, PT_skip, or None (no change)

Returns:

The current configuration for processing xsi:type attributes

_InterpretTypeAttribute(self, type_name, ns_ctx, fallback_namespace, type_class)

source code

Interpret the value of an xsi:type attribute as configured.

Parameters:

type_name - The QName value from the attribute
ns_ctx - The NamespaceContext within which the type_name should be resolved
fallback_namespace - The namespace that should be used if the type name has no prefix
type_class - The value to return if the type name is missing or acceptably invalid @raises pyxb.BadDocumentError: if the processing type configuration is PT_strict and the type name fails to resolve to a type definition that is consistent with any provided type_class.

_defineBuiltins_ox(self, structures_module)

source code

Ensure this namespace is ready for use.

Overrides base class implementation, since there is no schema for this namespace.

Overrides: Namespace._defineBuiltins_ox

Class Variable Details

[hide private]

PT_strict

xsi:type is validated and supersedes the declared type. If no xsi:type is present, the declared element type will be used. If xsi:type is present, it must resolve to valid type. The resolved type must be a subclass of the declared type (if available), and will be used for the binding.

Value:

'strict'

PT_lax

xsi:type supersedes the declared type without validation. If no xsi:type is present, or it is present and fails to resolve to a type, the declared element type will be used. If xsi:type is present and resolves to valid type, that type will be used for the binding, even if it is not a subclass of the declared type.

Value:

'lax'

PT_skip

xsi:type attributes are ignored. The declared element type will be used.

Value:

'skip'
