如何在 C# 中获取 XML 节点的字符串

Question

enter code herein the XML document :

<foo>
  <bar><para> test </para> </bar>
  <bar>text</bar>
  <bar>stackoverflow</bar>
</foo>

I am trying to parse it and only get the Strings in bar; by using this way:

[function where node is the foo]

foreach (XmlNode subNode in node.ChildNodes)
{

 if (subNode.Name == "bar")
 {
    if (!String.IsNullOrWhiteSpace(subNode.InnerText))
     Debug.WriteLine(subNode.Name + " - " subNode.InnerText);
 }

}

However it gives me test

Thanks

This is what you are looking for (EDITTED based on you updated question)

XDocument doc = XDocument.Load(path to your xml file);
XNamespace ns = "http://docbook.org/ns/docbook";

var result = doc.Root.Descendants(ns + "para")
                     .Where(x => x.FirstNode.NodeType == System.Xml.XmlNodeType.Text)
                     .Select(x => x.Value)
                     .ToList();

In your updated xml I see you are using a namespace so the name of your node is not para but it's theNameSpace + "para" . The namespace is defined in the first line of your xml file. Also you can see this sample too.

Do you want "test"? Try following :

            string input =
                "<foo>" +
                  "<bar><para> test </para> </bar>" +
                  "<bar>text</bar>" +
                  "<bar>stackoverflow</bar>" +
                "</foo>";


            XDocument doc = XDocument.Parse(input);

            List<string> bars = doc.Descendants("bar").Where(x => x.NextNode != null).Select(x => (string)((XElement)x.NextNode)).ToList();
