The above code produces no output at all. The pageReader() function is
defined but never called.
If we add a few lines at the bottom:
if __name__ == '__main__':
print pageReader('http://www.cert.org/nav/cert_announcements.rss')
Then we get some output:

You haven't included the BeautifulSoup code which attempts to parse the XML,
so it's impossible to say exactly what the error is.
However, I have a guess: you said you're trying to return the first
child. Based on the above output, the first child is the <channel>
element, not an <item> element. Perhaps that's the issue?
