    print rss.lastErrorText() + "\n"
    exit

rssChannel = rss.GetChannel(0)
if (rssChannel == nil )
    print "No channel found in RSS feed." + "\n"

print "Title: " + rssChannel.getString("title") + "\n";
print "Link: " + rssChannel.getString("link") + "\n";
print "Description: " + rssChannel.getString("description") + "\n";

#  For each item in the channel, display the title, link,
#  publish date, and categories assigned to the post.
numItems = rssChannel.get_NumItems()

for i in 0 .. numItems - 1
    rssItem = rssChannel.GetItem(i)

    print "----" + "\n";
    print "Title: " + rssItem.getString("title") + "\n";
    print "Link: " + rssItem.getString("link") + "\n";
    print "pubDate: " + rssItem.getString("pubDate") + "\n";

    numCategories = rssItem.GetCount("category")

    if (numCategories > 0)
        for j in 0 .. numCategories - 1
            print "    category: " + rssItem.mGetString("category",j) + "\n";
