Question

I’m making for my college an application which gathers data out from the XML. Beside the rest of the class am I making this in the Modern UI of Windows 8 which is working great for me except for one little thing.

When I gather the child nodes of a specific node do I get non-existent/empty values with it.
The values I should get are these.

• Hello
• Bye
• Hello World

But what I get into my list view are the following..
(The . means empty)

• .
• Hello
• .
• Bye
• .
• Hello World
• .

The code I use to get the items in the list view is the following.

        foreach (IXmlNode Node in XmlFile.SelectSingleNode("XML").SelectSingleNode("List").ChildNodes)
        {
            lvList.Items.Add(Node.InnerText.ToString());
        }

How do I get rid of the empty values?

Answer 1

lvList = XmlFile.SelectSingleNode("XML")
              .SelectSingleNode("List")
              .ChildNodes
              .Cast<XmlNode>()
              .Select(n => n.InnerText)
              .Where(s => !string.IsNullOrWhiteSpace(s))
              .ToList();

Or:

 foreach (IXmlNode Node in XmlFile.SelectSingleNode("XML").SelectSingleNode("List").ChildNodes)
    {
        string nodeText = Node.InnerText;
        if (!string.IsNullOrWhiteSpace(nodeText))
            lvList.Items.Add(nodeText);
    }
