Question

我真的只是想选择

中列出的值

    SOPDetail  
    TargetInfo   
DomesticJurisidiction

每个都是另一个的子节点。当我进行迭代时，我找到了节点DomesticJurisidiction，但是当我选择使用xpath时，我无法找到它。有没有人建议为什么？

        /*XmlNode targetNode = xDoc.SelectSingleNode("/SOPDetail/TargetInfo/DomesticJurisidiction");
        string haha = targetNode.InnerXml;*/

        foreach (XmlNode xmlNode in xDoc.ChildNodes)
        {
            Console.WriteLine(xmlNode.Name);
            foreach (XmlNode chldNode in xmlNode.ChildNodes)
            {
                Console.WriteLine(chldNode.Name);
                foreach (XmlNode cNode in chldNode.ChildNodes)
                {
                    Console.WriteLine(cNode.Name + ":" + cNode.InnerXml);
                }
            }
        }

就像我提到的foreach迭代完美地找到了这个节点，为什么我不能用SelectsingleNode选择它？

Answer 1

不要忘记使用Xml名称空间

XmlNamespaceManager nsMgr = new XmlNamespaceManager(xDoc.NameTable);
nsMgr.AddNamespace("x", "http://usop.ctadvantage.com/");
XmlNode targetNode = xDoc.SelectSingleNode("/x:SOPDetail/x:TargetInfo/x:DomesticJurisdiction", nsMgr);

Answer 2

你拼错了：

   /*XmlNode targetNode = xDoc.SelectSingleNode("/SOPDetail/TargetInfo/DomesticJurisidiction");

<强> DomesticJurisidiction

VS

<强> DomesticJurisdiction

Xmldoc .selectsinglenode返回null
