some simple XML (opml) parsing in Python

Say you have an opml file, whose filename is stored in the variable "filename":

from xml.dom import minidom
xmldoc = minidom.parse(filename)

"""
Print all the feed urls in the file
"""

for x in xmldoc.getElementsByTagName('outline'):
   if x.attribute.has_key('xmlUrl'):
      print(x.attributes["xmlUrl"].value)

Where your opml doc probably looks like:

<opml>
   <head>
      <title>Title for document</title>
   </head>
   <body>
      <outline text="somerssfeedtext" title="somerssfeedtitle" htmlUrl="urltofeedssite" xmlUrl="urltofeed">
      ...
      ... (more outline elements)
   </body>
</opml>

For more xml/python goodness look here.

If you want to use xpath/xml/python, look here.

OpenID

Here is a screencast on openid. I like the fact that you can use your own domain name as an OpenID. I doubt some of the main sites I visit (hotmail, gmail, blogger) will use OpenID, but it would make things so much easier.
