Try this:
from xml.dom.minidom import getDOMImplementation
impl = getDOMImplementation()
dt = impl.createDocumentType("employees", "-//ICES//DTD ICES
EMPLOYEES//EN", "")
doc = impl.createDocument(None, "employees", dt)
root = doc.documentElement
node = doc.createElement("foo")
node.setAttribute("some","attribute")
node.setAttribute("attr","value")
root.appendChild(node)
print doc.toxml()
But unless you *have* to use DOM for some reason, better switch to
another, more "pythonic" library. Like ElementTree or lxml (both implement
the same interface); the former comes with Python 2.5, the later you can
get from http://codespeak.net/lxml
import xml.etree.ElementTree as ET
root = ET.Element("employees")
ET.SubElement(root, "foo", some="attribute", attr="value")
ET.dump(root)
# <employees><foo attr="value" some="attribute" /></employees>
# ElementTree cannot generate a doctype header, do it by hand
f = open("test.xml", "w")
f.write('<?xml version="1.0" encoding="utf-8"?>\n')
f.write('<!DOCTYPE employees PUBLIC "-//ICES//DTD ICES EMPLOYEES//EN"
"">\n')
f.write(ET.tostring(root))
f.close()
(note: the lxml version may have doctype support)
