要删除包含 <CODE>98CA</CODE>的party的节点！   当判断的时候，该怎么写？
         xmlDoc.Load(xmlFileName); //加载XML文档
                   XmlNodeList nodes;
            XmlElement root = xmlDoc.DocumentElement;
            nodes = root.SelectNodes("//PARTY//CODE");

            // nodes = root.SelectNodes();

            foreach (XmlNode node in nodes)
            {
                
                    node.ParentNode.RemoveChild(node);
               

            }
不知道98CA的条件怎么添加上去，请高手指点！  在线等
