XSI attributes for schema instances

class schrodinger.application.matsci.qexsd.qespresso.xsdtypes.xsdtypes.XSDType(name, python_type, validators=None, to_python=None, from_python=<type 'str'>)

Bases: object

Base class for representing generic XSD types. Use this class for create XSD built-in types.

An instance contains a Python’s type transformation ana a list of validator functions.

Use Python’s types conversion:

Decoding from XML: python_type(value) Encoding to XML: str(value)

basename()

Get the name of the type without prefix or namespace URI.

decode(text)

Transform an XML text into a Python object. :param text: XML text

encode(obj)

Transform a Python object into an XML string. :param obj: The Python object that has to be encoded in XML

get_lengths(only_lists=True)

get_rank()

The rank of the XSDType-only instance (an XSD builtin type) is always 0.

is_list()

validate(value)

Validator for decoded values. :param value: The Python’s object that has to be validated

class schrodinger.application.matsci.qexsd.qespresso.xsdtypes.xsdtypes.XSDSimpleType(base_type, elem, name=None, is_list=False, length=None, validators=None, enumeration=None)

Bases: schrodinger.application.matsci.qexsd.qespresso.xsdtypes.xsdtypes.XSDType

A class for represent XSD schema simple type.

decode(text)

encode(obj)

get_lengths(only_lists=True)

Get the lengths defined for the XSD type.

Parameters:only_lists – Include lengths defined for other types. Returns:a list with defined lengths

get_rank()

Compute the pseudo-dimension of the XSDSimpleType, considering the dimension of the base type.

Returns:int

is_list()

validate(value)

Bases: schrodinger.application.matsci.qexsd.qespresso.xsdtypes.xsdtypes.XSDSimpleType

A class for represent XSD schema simple type.

class schrodinger.application.matsci.qexsd.qespresso.xsdtypes.xsdtypes.XSDElement(name, path, xsd_type, attrib=None)

Bases: object

Support structure to associate an element and its attributes with XSD simple types.

attrib = None

Attributes of element declaration (eg. minOccurs, default …)

basename()

Get the name of the element without prefix or namespace URI.

get_default()

get_max_occurs()

get_min_occurs()

get_type()

is_optional()

name = None

The name is the element tag

path = None

The XPath of this element

xsd_type = None

XSD type of the element

schrodinger.application.matsci.qexsd.qespresso.xsdtypes.xsdtypes.xsd_simple_type_factory(elem, **kwargs)

Factory function for XSD simple type declaration.

Parameters:elem – The ElementTree’s Element. It must be

a simpleType declaration element. :param kwargs: Various lookup tables and parameters, dependant by the context where the function is called. :return: a couple with the type_name, that maybe an empty string, and the XSDSimpleType instance that represents the XSD declaration.

schrodinger.application.matsci.qexsd.qespresso.xsdtypes.xsdtypes.xsd_attribute_type_factory(elem, **kwargs)

Factory function for XSD attribute declaration.

Parameters:elem – The ElementTree’s Element. It must be

a attribute declaration element. :param kwargs: Various lookup tables and parameters, dependant by the context where the function is called. :return: a couple with the attribute name and the instance of XSDType associated with it.

schrodinger.application.matsci.qexsd.qespresso.xsdtypes.xsdtypes.xsd_complex_type_factory(elem, **kwargs)

Factory function for XSD complex type declaration.

Parameters:elem – The ElementTree’s Element. It must be

a complexType declaration element. :param kwargs: Various lookup tables and parameters, dependant by the context where the function is called. :return: a couple with the type_name, that maybe an empty string, and the XSDComplexType instance that represents the XSD declaration.

schrodinger.application.matsci.qexsd.qespresso.xsdtypes.xsdtypes.xsd_element_factory(elem, xsd_element=None, **kwargs)

Factory function for XSD element declaration. The function walks through complexTypes to find declarations of descendant XSD elements.

Parameters:elem – The ElementTree’s Element. It must be

an element declaration element. :param xsd_element: The complex type, if it’s already created. :param kwargs: Various lookup tables and parameters, dependant by the context where the function is called. An xsd_elements dictionary is needed as the destination of the XSD element declarations.
