[XML-SIG] Win32 and 4DOM

[Ludvig Svenonius]

I'm having a hassle getting 4DOM to work under Windows. I'm getting tragic
stack traces of different kinds depending on whether i try to run it in IDLE
or at the command line.

In IDLE:
>>> from Ft.Dom import Ext
>>> from Ft.Dom.Ext.Reader import Sax
>>> dom = Sax.FromXmlFile("Ft\\Dom\\demo\\addr_book1.xml")
Exception in Tkinter callback
Traceback (innermost last):
  File "C:\Program Files\Python\Lib\lib-tk\Tkinter.py", line 764, in
__call__
    return apply(self.func, args)

    if not self.args:

At the command prompt:
C:\Program Files\Python\Ft\Dom\demo>python dom_from_xml_file.py
addr_book1.xml
SAXException caught: No parsers found
Traceback (innermost last):

In the command-line Python interpreter:

Traceback (innermost last):

  File "Ft\Dom\Node.py", line 300, in _4dom_validateNode
    raise DOMException(HIERARCHY_REQUEST_ERR)
Ft.Dom.DOMException

What is it I'm doing wrong? I'm using Python 1.5.2 and 4DOM 0.9.3.

Thankful for any suggestions,
