"""
A basic example of using the DOM to create an XML document from scratch.
"""
from xml.dom import ext

if __name__ == '__main__':
#Create a doctype using document type name, sysid and pubid
dt = implementation.createDocumentType('mydoc', '', '')
#Create a document using document element namespace URI, doc element
#name and doctype. This automatically creates a document element
#which is the single element child of the document
doc = implementation.createDocument(None, 'mydoc', dt)
#Get the document element
doc_elem = doc.documentElement
#Create an element: the Document instanmce acts as a factory
