获取XML文件

private XmlDocument GetDoc(string strpath)        {            if (System.IO.File.Exists(strpath) == true)            {                XmlDocument document = new XmlDocument();                document.Load(strpath);//加载xml文档                return document;            }            else            {                return null;            }        }

解析XML

XmlNode newNode = document.DocumentElement.SelectSingleNode("//layer[@name='" + 名称+ "']");if (newNode != null){　　string aliasName = newNode.Attributes["别名"].Value.ToString(); 　　string strDes = newNode.Attributes["描述"].Value.ToString();}

 

XmlNode SymbologyNode = NameNode.SelectSingleNode("//Symbology[@FieldValue='" + strieldValue + "']");

 

XmlNode SymbologyNode = NameNode.SelectSingleNode("//layer[@name='" + layerName + "']//Symbology[@FieldValue='" + strieldValue + "']");
