type NamespaceContext

Overrides: object.__str__

(inherited documentation)

The default namespace in effect at this node. E.g., xmlns="URN:default".

The target namespace in effect at this node. Usually from the targetNamespace attribute. If no namespace is specified for the schema, an absent namespace was assigned upon creation and will be returned.

Map from prefix strings to Namespace instances associated with those prefixes. The prefix None identifies the default namespace.

Get the NamespaceContext instance that was assigned to the node.

If none has been assigned and keyword parameters are present, create one treating this as the root node and the keyword parameters as configuration information (e.g., default_namespace).

Raises:

• pyxb.LogicError - no context is available and the keywords required to create one were not provided

Determine the namespace context that should be associated with the given node and, optionally, its element children.

Parameters:

• dom_node (xml.dom.Element) - The DOM node
• parent_context (NamespaceContext) - Optional value that specifies the context associated with dom_node's parent node. If not provided, only the xml namespace is in scope.
• recurse (bool) - If True (default), create namespace contexts for all element children of dom_node
• default_namespace (NamespaceContext) - Optional value to set as the default namespace. Values from parent_context would override this, as would an xmlns attribute in the dom_node.
• target_namespace (NamespaceContext) - Optional value to set as the target namespace. Values from parent_context would override this, as would a targetNamespace attribute in the dom_node
• in_scope_namespaces (dict mapping string to Namespace.) - Optional value to set as the initial set of in-scope namespaces. The always-present namespaces are added to this if necessary.

Overrides: object.__init__

Convert the provided name into an ExpandedName, i.e. a tuple of Namespace and local name.

If the name includes a prefix, that prefix must map to an in-scope namespace in this context. Absence of a prefix maps to defaultNamespace(), which must be provided (or defaults to the target namespace, if that is absent).

Parameters:

• name (str or unicode) - A QName.
• name (str or unicode) - Optional namespace to use for unqualified names when there is no default namespace. Note that a defined default namespace, even if absent, supersedes this value.

Returns:

An ExpandedName tuple: ( Namespace, str )

Raises:

• pyxb.SchemaValidationError - The prefix is not in scope
• pyxb.SchemaValidationError - No prefix is given and the default namespace is absent
