This module contains XMLSchema class for xsdtypes package

class schrodinger.application.matsci.qexsd.qespresso.xsdtypes.xmlschema.XMLSchema(xsd_file)

Bases: object

Class to wrap an XML Schema for types lookups.

XML_SCHEMA_NAMESPACES = {'xs': 'http://www.w3.org/2001/XMLSchema', 'xsd': 'http://www.w3.org/2001/XMLSchema', 'xsi': 'http://www.w3.org/2001/XMLSchema-instance'}

__init__(xsd_file)

namespaces

Namespaces used by XSD file

types

Map XSD global types to XSDType instance

attributes

Map XSD global attributes to XSDType instance

attribute_groups

Group XSD attributes definitions

elements

Map XSD global elements to XSDType instance

groups

Group XSD elements definitions

target_namespace

Target namespace URI

target_prefix

Namespace prefix for declarations

get_type(type_name)

Return the XSD type instance corresponding to the argument.

Parameters

type_name – Name of the type. Types in the schema’s

namespace have to be provided with namespace URI or prefix. Unqualified names are interpreted as typed of xsd/xs namespace. :return: XSDType or XSDSimpleType instance

get_element(element_path)

get_element_tag(element_path)

Return the XSD type instance of the element.

Parameters

element_path – The absolute path to the element. Schema’s

namespace prefixes or URIs are stripped from the path. :return: XSDType, XSDSimpleType or XSDComplexType instance

get_attributes(element_path)

get_element_type(element_path)

Return the XSD type instance of the element.

Parameters

element_path – The absolute path to the element. Schema’s

namespace prefixes or URIs are stripped from the path. :return: XSDType, XSDSimpleType or XSDComplexType instance

get_attribute_type(attribute_name, element_path)

Return the XSD type instance of the attribute.

Parameters

attribute_name – The name of the attribute. Schema’s

namespace prefix or URI is stripped from the name. :param element_path: The absolute path to the element. Schema’s namespace prefixes or URIs are stripped from the path. :return: XSDType or XSDSimpleType instance

get_element_default(element_path)

Return the default of the element.

Parameters

element_path – The absolute path to the element. Schema’s

namespace prefixes or URIs are stripped from the path. :return: XSDType, XSDSimpleType or XSDComplexType instance

get_attribute_default(attribute_name, element_path)

Return the XSD type instance of the attribute.

Parameters

attribute_name – The name of the attribute. Schema’s

namespace prefix or URI is stripped from the name. :param element_path: The absolute path to the element. Schema’s namespace prefixes or URIs are stripped from the path. :return: XSDType or XSDSimpleType instance

find(path, namespaces=None)

Find first matching element by tag name or path.

Parameters

• path – is a string having either an element tag or an XPath,

• namespaces – is an optional mapping from namespace prefix to full name.

Returns

the first matching element, or None if no element was found

findall(path, namespaces=None)

Find all matching subelements by tag name or path.

Parameters

• path – is a string having either an element tag or an XPath,

• namespaces – is an optional mapping from namespace prefix to full name.

Returns

the first matching element, or None if no element was found

getroot()

Return root element of the XML schema tree.

iselement(elem)

Checks if an element instance appears to be a valid element object. :param elem:

iter(tag=None)

Create and return an iterator that loops over all elements in this tree, in document order.

Parameters

tag – is a string with the tag name to iterate over

(default is to return all elements).

validate(xml_config)

Validate the configuration with XSD and with optional parameter dependencies. :param xml_config:
