            XmlDocument doc = new XmlDocument();
            doc.Load(filepath);
            XmlNode xn = doc.ChildNodes[1].ChildNodes[1].ChildNodes[0].ChildNodes[0];            List<XmlNode> lx=new List<XmlNode>();
            for (int i = 0; i < xn.ChildNodes.Count; i++)
{
                lx.Add(xn.ChildNodes[i]);  
}            foreach (var item in lx)
            {
                if (item.Name=="moi"&&item.Attributes["xsi:type"].Value=="APPCERT")
                {

Answer 1

我还说你那个怎么结贴了，原来又发了一个。之前没在额。
我这个比楼上那位稍微简洁了一点儿string xmlpath = @"F:\Test\Test\Test\XMLFile1.xml";
            XmlDocument xml = new XmlDocument();
            xml.Load(xmlpath);//加载xml文件，xmlpath为xml文件的路径
            XmlNode key = xml.ChildNodes[1].ChildNodes[1].ChildNodes[0].ChildNodes[0];//<module xsi:type="LTESiteModule">
            XmlNodeList nodes = key.ChildNodes;
            for (int i = 0; i < nodes.Count; i++)
            {
                XmlElement node = (XmlElement)nodes[i];
                if (node.Name == "moi" && node.GetAttribute("xsi:type") == "APPCERT")
                {
                    key.RemoveChild(node);
                    i -= 1;
                }
            }
            xml.Save(xmlpath);

Answer 2

如果有多个<subsession></subsession>，代码怎么写呢

Answer 3

            string xmlpath = @"F:\Test\Test\Test\XMLFile1.xml";
            XmlDocument xml = new XmlDocument();
            xml.Load(xmlpath);//加载xml文件，xmlpath为xml文件的路径
            for (int j = 1; j < xml.ChildNodes[1].ChildNodes.Count; j++)//遍历session
            {
                XmlNode key = xml.ChildNodes[1].ChildNodes[j].ChildNodes[0].ChildNodes[0];
                XmlNodeList nodes = key.ChildNodes;
                for (int i = 0; i < nodes.Count; i++)
                {
                    XmlElement node = (XmlElement)nodes[i];
                    if (node.Name == "moi" && node.GetAttribute("xsi:type") == "APPCERT")
                    {
                        key.RemoveChild(node);
                        i -= 1;
                    }
                }
            }
            xml.Save(xmlpath);

Answer 4

            string xmlpath = @"F:\Test\Test\Test\XMLFile1.xml";
            XmlDocument xml = new XmlDocument();
            xml.Load(xmlpath);//加载xml文件，xmlpath为xml文件的路径
            for (int j = 1; j < xml.ChildNodes[1].ChildNodes.Count; j++)//遍历session
            {
                XmlNode key = xml.ChildNodes[1].ChildNodes[j].ChildNodes[0].ChildNodes[0];
                XmlNodeList nodes = key.ChildNodes;
                for (int i = 0; i < nodes.Count; i++)
                {
                    XmlElement node = (XmlElement)nodes[i];
                    if (node.Name == "moi" && node.GetAttribute("xsi:type") == "APPCERT")
                    {
                        key.RemoveChild(node);
                        i -= 1;
                    }
                }
            }
            xml.Save(xmlpath);
