generateDS Description

Generate data structures from XML schema generateDS generates Python data structures (for example, class definitions) from an XML Schema document. These data structures represent the elements in an XML document described by the XML Schema. generateDS is also able to generate parsers that load an XML document in the data structures. In addition, a separate file containing subclasses (stubs) is optionally generated. The user can add methods to the subclasses in order to process the contents of an XML document.The generated Python code contains:· A class definition for each element defined in the XML Schema document.· A main and driver function that can be used to test the generated code.· A parser that will read an XML document which satisfies the XML Schema from which the parser was generated. The parser creates and populates a tree structure of instances of the generated Python classes.· Methods in each class to export the instance back out to XML (method export) and to export the instance to a literal representing the Python data structure (method exportLiteral).The generated classes contain the following:· A constructor method (__init__), with member variable initializers.· Methods with names 'getX' and 'setX' for each member variable 'X' or, if the member variable is defined with maxOccurs="unbounded", methods with names 'getX', 'setX', 'addX', and 'insertX'.· A "build" method that can be used to populate an instance of the class from a node in a minidom tree.· An "export" method that will write the instance (and any nested sub-instances) to a file object as XML text.· An "exportLiteral" method that will write the instance (and any nested sub-instances) to a file object as Python literals (text). Requirements: · Python What's New in This Release: · One more fix for abstract types -- When the implementation element/class for an abstract class exports itself, it adds the xsi:type="class_name" attribute. · A minor fix to handling namespace prefix and the -a command line option. · Additional fixes so that in constructors (__init__), all instance variables are initialized to None. · Some fixes to quoting and escaping quotes when exporting attribute values. Thanks to Kerim Mansour for help with this.
