Method Details

[hide private]

implementation(self)

source code

The DOMImplementation object to be used.

Defaults to pyxb.utils.domutils.GetDOMImplementation(), but can be overridden in the constructor call using the implementation keyword.

requireXSIType(self)

source code

Indicates whether {xsi:type<http://www.w3.org/TR/xmlschema-1/#xsi_type>} should be added to all elements.

Certain WSDL styles and encodings seem to require explicit notation of the type of each element, even if it was specified in the schema.

This value can only be set in the constructor.

reset(self, **kw)

source code

Reset this instance to the state it was when created.

This creates a new root document with no content, and flushes the list of namespaces for the document. The defaultNamespace and requireXSIType are not modified.

init(self, implementation=None, default_namespace=None, require_xsi_type=False, namespace_prefix_map=None)
(Constructor)

source code

Create a new instance used for building a single document.

Parameters:

implementation - The xml.dom implementation to use. Defaults to the one selected by GetDOMImplementation.
default_namespace (pyxb.namespace.Namespace) - The namespace to configure as the default for the document. If not provided, there is no default namespace.
require_xsi_type (bool) - If True, an xsi:type attribute should be placed in every element.
namespace_prefix_map (map from pyxb.namespace.Namespace to str) - A map from pyxb.namespace.Namespace instances to the preferred prefix to use for the namespace in xmlns declarations. The default one assigns 'xsi' for the XMLSchema instance namespace.

Raises:

pyxb.LogicError - the same prefix is associated with multiple namespaces in the namespace_prefix_map.

Overrides: object.__init__

addAttribute(self, element, expanded_name, value)

source code

Add an attribute to the given element.

Parameters:

element (xml.dom.Element) - The element to which the attribute should be added
expanded_name (pyxb.namespace.Namespace or str or unicode) - The name of the attribute. This may be a local name if the attribute is not in a namespace.
value (str or unicode) - The value of the attribute

finalize(self)

source code

Do the final cleanup after generating the tree. This makes sure that the document element includes XML Namespace declarations for all namespaces referenced in the tree.

Returns: xml.dom.Document: The document that has been created.

createChildElement(self, expanded_name, parent=None)

source code

Create a new element node in the tree.

Parameters:

expanded_name (pyxb.namespace.ExpandedName or str or unicode) - The name of the element. A plain string indicates a name in no namespace.
parent - The node in the tree that will serve as the child's parent. If None, the document element is used. (If there is no document element, then this call creates it as a side-effect.)

Returns: xml.dom.Element

A newly created DOM element
