我的代码是：

  string xml = @"C:\Users\baseer.haider\Documents\visual studio 2010\Projects\CheckReadXML\CheckReadXML\ACS.xml";
            XmlDocument acsXml = new XmlDocument();
            acsXml.Load(xml);
            XmlNodeList acsNode = acsXml.DocumentElement.SelectNodes("//AttributeStatement//Attribute");

            foreach (XmlNode node in acsNode)
            {
                if (node.Attributes["Name"] != null)
                {
                    if (node.Attributes["Name"].Value == "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress")
                    {
                        var innerNode = node.SelectSingleNode("//AttributeValue");
                        Console.WriteLine(innerNode.InnerText);
                    }

                }

我想从以下XML加载节点但我无法加载它，因为当我使用此代码选择该节点时 XmlNodeList acsNode = acsXml.DocumentElement.SelectNodes("//AttributeStatement//Attribute");

acsNode为空。任何人都可以解决这个问题吗？

Answer 1

使用Linq2Xml要容易得多。

XDocument xDoc = XDocument.Load(fileName);
XNamespace ns = "urn:oasis:names:tc:SAML:2.0:assertion";

var attvals = xDoc.Descendants(ns + "AttributeValue")
                  .Select(x => x.Value)
                  .ToList();

Answer 2

使用 LINQ2XML

XElement doc = XElement.Load("yourStream.xml");
XNamespace t="http://schemas.xmlsoap.org/ws/2005/02/trust";
XNamespace a="urn:oasis:names:tc:SAML:2.0:assertion";

var lstElmVal=doc.Descendants(t+"RequestedSecurityToken")
.Descendants(t+"Assertion")
.Element(a+"AttributeStatement")
.Elements(a+"Attribute")
.Where(x=>x.Attribute("Name").Value=="http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress")
.Select(y=>y.Value);

//lstElmVal now contains your required data
