schrodinger.application.matsci.qexsd.qespresso.xsdtypes.xmlschema module

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)

Initialize self. See help(type(self)) for accurate signature.

namespaces = None

Namespaces used by XSD file

types = None

Map XSD global types to XSDType instance

attributes = None

Map XSD global attributes to XSDType instance

attribute_groups = None

Group XSD attributes definitions

elements = None

Map XSD global elements to XSDType instance

groups = None

Group XSD elements definitions

target_namespace = None

Target namespace URI

target_prefix = None

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:
