为什么找不到xml中的节点？

[szjarvis]

我的ＸＭＬ文件是.txt文件，里面格式是ＸＭＬ的，用以下方法找不到节点SuccessfulValidations．

                    XmlDocument doc = new XmlDocument();
                    doc.Load(txtFile);
                    XmlNode node = doc.SelectSingleNode("SuccessfulValidations");

请高手帮帮忙，我想取节点SuccessfulValidations下的所有子节点，从而取所有子点点下的属性．

整个XML文件就是这样子，要找的节点不是根．

有人知道为什么会这样吗？

[king4323210]

方式错了 前面要加root节点 比如/

有namespace，下面是用System.Xml.Linq来获取的

string xml = @"

            XElement root = XElement.Parse(xml);
            var nsp = root.GetDefaultNamespace().NamespaceName;
            var ele = root.Element(XName.Get("ComputerBuildReportAcks", nsp))
                .Element(XName.Get("ComputerBuildReportAck", nsp))
            .Element(XName.Get("SuccessfulValidations", nsp));

要加上路径啊 doc.SelectSingleNode("ComputerBuildReportAckResponse\ComputerBuildReportAcks\ComputerBuildReportAck\SuccessfulValidations");

[WM_JAWIN]

好像是"/"这种斜杠

扩展名改成.xml试过吗

[szjarvis]

扩展名改成.xml也试过，也是不行．我用XmlNodeReader reader = new XmlNodeReader(doc);去做while (reader.Read())循环是可以的．

[於黾]

放出xml文件里关于SuccessfulValidations的那一段数据

[娃都会打酱油了]

你这个是根节点吧？
