I tried this and it works. This is short and you can read the description easily. Assume test.xml is the file you want to read . val will contain the value of decription. Please note that since you are using colon in your xml element name , it is important that you associate a namespace in your XML file for sct.

XElement  RootNode = System.Xml.Linq.XElement.Load("d:/test.xml");   
foreach (XElement child in RootNode.Elements())
{
    if (child.Name.LocalName.Equals("description"))
    {
        string val = child.Value.ToString();
    }
}

Reading Xml with XmlReader : 

   XmlReader xReader = XmlReader.Create(new StringReader(xmlNode));
while (xReader.Read())
{
    switch (xReader.NodeType)
    {
        case XmlNodeType.Element:
            listBox1.Items.Add("<" + xReader.Name + ">");
            break;
        case XmlNodeType.Text:
            listBox1.Items.Add(xReader.Value);
            break;
        case XmlNodeType.EndElement:
            listBox1.Items.Add("");
            break;
    }
}

Reading XML with XmlTextReader : 

 XmlTextReader xmlReader = new XmlTextReader("d:\\product.xml");
 while (xmlReader.Read())
    {
switch (xmlReader.NodeType)
{
    case XmlNodeType.Element:
        listBox1.Items.Add("<" + xmlReader.Name + ">");
        break;
    case XmlNodeType.Text:
        listBox1.Items.Add(xmlReader.Value);
        break;
    case XmlNodeType.EndElement:
        listBox1.Items.Add("");
        break;
}
 }

Try like this:

foreach(XmlNode node in doc.DocumentElement.ChildNodes){
   string text = node.InnerText; 
}

You can read the attribute as

string text = node.Attributes["sct:description"].InnerText;

You can also refer: LINQ to XML

LINQ to XML provides an in-memory XML programming interface that leverages the .NET Language-Integrated Query (LINQ) Framework. LINQ to XML uses the latest .NET Framework language capabilities and is comparable to an updated, redesigned Document Object Model (DOM) XML programming interface.
