读取xml节点的数据总结 /*读取xml数据两种xml方式*/<aaa> <bb>something</bb> <cc>something</cc></aaa> <aaa> <add key="123" value="321"/></aaa> /*第一种方法*/DS.ReadXml("your xmlfile name");Container.DataItem("bb");Container.DataItem("cc");DS.ReadXmlSchema("your xmlfile name"); /*第二种方法*/<aaa> <add key="123" value="321"/></aaa>如果我要找到123然后取到321应该怎么写呢？ using System.XML;XmlDataDocument xmlDoc = new System.Xml.XmlDataDocument();xmlDoc.Load(@"c:\Config.xml");XmlElement elem = xmlDoc.GetElementById("add");string str = elem.Attributes["value"].Value /*第三种方法: SelectSingleNode 读取两种格式的xml *---/--------------------------------------------------------------------<?xml version="1.0" encoding="utf-8" ?><configuration> <appSettings> <ConnectionString>Data Source=yf; user id=ctm_dbo;password=123</ConnectionString> </appSettings></configuration>--------------------------------------------------------------------------XmlDocument doc = new XmlDocument();doc.Load(strXmlName); XmlNode node=doc.SelectSingleNode("/configuration/appSettings/ConnectionString"); if(node!=null) { string k1=node.Value; //null string k2=node.InnerText;//Data Source=yf; user id=ctm_dbo;password=123 string k3=node.InnerXml;//Data Source=yf; user id=ctm_dbo;password=123 node=null; } ********************************************************************<?xml version="1.0" encoding="utf-8" ?><configuration> <appSettings> <add key="ConnectionString" value="Data Source=yf; user id=ctm_dbo;password=123" /> </appSettings></configuration>**--------------------------------------------------------------------** XmlNode node=doc.SelectSingleNode("/configuration/appSettings/add"); if(node!=null) { string k=node.Attributes["key"].Value; string v=node.Attributes["value"].Value; node=null; }*--------------------------------------------------------------------* XmlNode node=doc.SelectSingleNode("/configuration/appSettings/add"); if(node!=null) { XmlNodeReader nr=new XmlNodeReader(node); nr.MoveToContent(); //检查当前节点是否是内容节点。如果此节点不是内容节点，则读取器向前跳至下一个内容节点或文件结尾。 nr.MoveToAttribute("value"); string s=nr.Value; node=null; }
