[Update on 2009-03-19]

• Simplified example code
• Added link to code sample on my skydrive

This simple example shows you how simple it is to search for tweets using Twitter’s Search API

Key techniques demonstrated in this sample code

• Using System.Net.WebClient to download a file
• Searching for nodes in System.Xml using namespaces
• Simple ATOM-feed parsing

Code is available here: http://cid-19ec39cb500669d8.skydrive.live.com/browse.aspx/Public/IronPython/Samples
