Foreach loop XmlNodeList

Question

Currently I have the following code:

XmlDocument xDoc = new XmlDocument();
xDoc.Load("http://api.twitter.com/1/statuses/user_timeline.xml?screen_name=twitter");

XmlNodeList tweets = xDoc.GetElementsByTagName("text");
foreach (int i in tweets)
{
    if (tweets[i].InnerText.Length > 0)
    {
         MessageBox.Show(tweets[i].InnerText);
    }
}

Which doesn't work, it gives me System.InvalidCastException on the foreach line.

The following code works perfectly (no foreach, the i is replaced with a zero):

XmlDocument xDoc = new XmlDocument();
xDoc.Load("http://api.twitter.com/1/statuses/user_timeline.xml?screen_name=twitter");

XmlNodeList tweets = xDoc.GetElementsByTagName("text");

if (tweets[0].InnerText.Length > 0)
{
     MessageBox.Show(tweets[0].InnerText);
}

Answer 1

tweets is a node list. I think that what you're trying to do is this:

XmlDocument xDoc = new XmlDocument();
xDoc.Load("http://api.twitter.com/1/statuses/user_timeline.xml?screen_name=twitter");

XmlNodeList tweets = xDoc.GetElementsByTagName("text");
for (int i = 0; i < tweets.Count; i++)
{
    if (tweets[i].InnerText.Length > 0)
    {
        MessageBox.Show(tweets[i].InnerText);
    }
}
