rss feed generation

[Blake Garner]

I'm looking for suggestions on how to approach generating rss feed
..xml files using python. What modules to people recommend I start
with?

Thanks!

I just rolled something with ElementTree. No idea how it
stacks up against validity checks, but it seems to be
accepted by a couple of standard feed readers.

(sorry; longish code segment)

<code>

from datetime import datetime
try:
from xml.etree import cElementTree as ET
except ImportError:
from elementtree import ElementTree as ET

class Feed (object):

ENCODING = "utf-8"

self.title = title
self.link = link

self.entries = []

def add_entry (self, title, link, content, summary=None, id=None, updated_on=None ):
self.entries.ap pend (
dict (
title=title,
link=link,

summary=summary ,
id=id or link,
updated_on=upda ted_on or datetime.now ()
)
)

def write_rss (self, ofile=sys.stdou t, encoding=ENCODI NG):
rss = ET.Element ("rss", version="2.0")
channel = ET.SubElement (rss, "channel")
ET.SubElement (channel, "title").te xt = self.title

ET.SubElement (channel, "description"). text = self.descriptio n

for entry in self.entries:

ET.SubElement (item, "link").tex t = entry['link']
ET.SubElement (item, "guid").tex t = entry['id']
ET.SubElement (item, "description"). text = entry['content']

ET.ElementTree (rss).write (ofile, encoding=encodi ng)

ET.SubElement (feed, "link", rel="self", href=self.link)
if self.descriptio n:
ET.SubElement (feed, "subtitle", type="text").te xt = self.descriptio n
if self.author:
name, email = self.author
author = ET.SubElement (feed, "author")
ET.SubElement (author, "name").tex t = name
ET.SubElement (author, "email").te xt = email
ET.SubElement (feed, "updated"). text = self.updated_on .isoformat ()

for entry in self.entries:

if entry['summary']:
ET.SubElement (e, "summary"). text = entry['summary']
ET.SubElement (e, "content", type="html").te xt = "<![CDATA[%s]]>" % entry['content']

ET.ElementTree (feed).write (ofile, encoding=encodi ng)

if __name__ == '__main__':
feed = Feed ("Feed for example.org", "http://example.org", author=("Tim Golden", "tim@example.or g"))
for i in range (5):

[... snip messy code ...]

Well that didn't come out very well. If anyone's interested,
I've dropped the module here:
