When posting code, templates, or tracebacks here, please enclose them between lines of three backtick - ` characters. This means you’ll have a line of ```, then your code (or template, or traceback), then another line of ```. This forces the forum software to keep those files formatted properly, which is important with Python.

Now, aside from that, the only package I see on PyPI is django-feedparser v 0.2.1, which is sadly out-of-date relative to the versions of Django and Python you’re using. If you’re trying to use this one, it’s no surprise that it’s failing.
(If this isn’t the package you’re using, please let us know what package you’re using.)

Hi,

There was an indenting and return issue in context_processor. It is working now. But I was surprised why showed another error, why it is not pointing exactly!
And Feedparser is working for me to fetch XML. I am using beautifulsoup also along with feedparser.

By the way, I am also surprised by seeing a quick response in Django forum! I have learned python and used Django for 2 months but Implementing strong features in my second project to learn!

Great!
