I have a GAE RSS reader demo / prototype working using Feedparser - http://deliciourss.appspot.com/. Here's some code -
Fetch your feed.
data = urlfetch.fetch(feedUrl)Parse with Feedparser
parsedData = feedparser.parse(data.content)Change some features of the feed
# set main section to description if empty for ix in range(len(parsedData.entries)): bItem = 0 if hasattr(parsedData.entries[ix],'content'): for item in parsedData.entries[ix].content: if item.value: bItem = 1 break if bItem == 0: parsedData.entries[ix].content[0].value = parsedData.entries[ix].summary else: parsedData.entries[ix].content = [{'value':parsedData.entries[ix].summary}]Template if you are using Django/webapp
<?xml version="1.0" encoding="utf-8"?><channel><title>{{parsedData.channel.title}}</title><url>{{feedUrl}}</url><id>{{parsedData.channel.id}}</id><updated>{{parsedData.channel.updated}}</updated>{% for entry in parsedData.entries %}<item><id>{{entry.id}}</id><title>{{entry.title}}</title><link> {% for link in entry.links %} {% ifequal link.rel "alternate" %} {{link.href|escape}} {% endifequal %} {% endfor %}</link><author>{{entry.author_detail.name}}</author><pubDate>{{entry.published}}</pubDate><description>{{entry.summary|escape}}</description> {% for item in entry.content %} {% if item.value %} <content>{{item.value|escape}}</content> {% endif %} {% endfor %}</item>{% endfor %}</channel>
