C# XML node with colon
- by Sticky
Hi, my code attempts to grab data from the RSS feed of a website. It grabs the nodes fine, but when attempting to grab the data from a node with a colon, it crashes and gives the error "Namespace Manager or XsltContext needed. This query has a prefix, variable, or user-defined function." The code is shown below:
WebRequest request = WebRequest.Create("http://buypoe.com/external.php?type=RSS2&lastpost=true");
WebResponse response = request.GetResponse();
StringBuilder sb = new StringBuilder("");
System.IO.StreamReader rssStream = new System.IO.StreamReader(response.GetResponseStream(), System.Text.Encoding.GetEncoding("utf-8"));
XmlDocument rssDoc = new XmlDocument();
rssDoc.Load(rssStream);
XmlNodeList rssItems = rssDoc.SelectNodes("rss/channel/item");
for (int i = 0; i < 5; i++)
{
XmlNode rssDetail;
rssDetail = rssItems.Item(i).SelectSingleNode("dc:creator");
if (rssDetail != null)
{
user = rssDetail.InnerText;
}
else
{
user = "";
}
}
I understand that I need to define the namespace, but am unsure how to do this. Help would be appreciated.
