      </nationalList>
    </SetNationalList>
  </s:Body>
</s:Envelope>

XDocument xdoc = XDocument.Parse(xml);
foreach (XElement element in xdoc.Descendants("nationalList"))
{
   MessageBox.Show(element.ToString());
}

我想遍历 nationalList 下的每个节点，但它对我不起作用，它完全跳过了 foreach 循环。我在这里做错了什么？

您没有包括命名空间，它是 "http://www.lge.com/ddc"，默认来自父元素:

XNamespace ns = "http://www.lge.com/ddc";
foreach (XElement element in xdoc.Descendants(ns + "nationalList"))
{
    ...
}
