<div style="color:Black;background-color:White; <pre>

C# Code to parse

<div style="color:Black;background-color:White; <pre>
XmlDocument doc = <span style="color:Blue; new XmlDocument();
doc.LoadXml(xml);
XmlNamespaceManager namespaceManager = <span style="color:Blue; new XmlNamespaceManager(doc.NameTable);
namespaceManager.AddNamespace(<span style="color:#A31515; "Agent", <span style="color:#A31515; "http://www.MyCompany.com/Product/Agent");


XmlNode node = doc.SelectSingleNode(<span style="color:#A31515; "/Agent:Work/Agent:WorkType"); <span style="color:Green; // Still getting error on this line.
[/code]


What am I missing here ? Please help.
