c對(duì)xml多屬性節(jié)點(diǎn)的增加,刪除,修改操作源碼

1、using System; using System.Collections; using System.ComponentModel; using System.Data; using System.Drawing; using System.Web; using System.Web.SessionState; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.HtmlControls; using System.Xml; private XmlDocument xmlDoc; /load x

2、ml file private void LoadXml() xmlDoc=new XmlDocument(); xmlDoc.Load(Server.MapPath("User.xml"); /添加節(jié)點(diǎn) private void AddElement() LoadXml(); XmlNode xmldocSelect=xmlDoc.SelectSingleNode("user"); XmlElement el=xmlDoc.CreateElement("person"); /添加person節(jié)點(diǎn) el.SetAttribute(&q

3、uot;name","風(fēng)云"); /添加person節(jié)點(diǎn)的屬性"name" el.SetAttribute("sex","女"); /添加person節(jié)點(diǎn)的屬性 "sex" el.SetAttribute("age","25"); /添加person節(jié)點(diǎn)的屬性 "age" XmlElement xesub1=xmlDoc.CreateElement("pass"); /添加person節(jié)點(diǎn)的里的節(jié)點(diǎn) xes

4、ub1.InnerText="123"/設(shè)置文本節(jié)點(diǎn) el.AppendChild(xesub1); XmlElement xesub2=xmlDoc.CreateElement("Address"); xesub2.InnerText="昆明"/設(shè)置文本節(jié)點(diǎn) el.AppendChild(xesub2); xmldocSelect.AppendChild(el); xmlDoc.Save(Server.MapPath("user.xml"); /修改節(jié)點(diǎn) private void UpdateElement()

5、LoadXml(); XmlNodeList nodeList=xmlDoc.SelectSingleNode("user").ChildNodes;/獲取bookstore節(jié)點(diǎn)的所有子節(jié)點(diǎn) foreach(XmlNode xn in nodeList)/遍歷所有子節(jié)點(diǎn) XmlElement xe=(XmlElement)xn;/將子節(jié)點(diǎn)類型轉(zhuǎn)換為XmlElement類型 if(xe.GetAttribute("name")="風(fēng)云")/如果name屬性值為“風(fēng)云” xe.SetAttribute("name",&

6、quot;發(fā)明"); /如果下面有子節(jié)點(diǎn)在下走 XmlNodeList nls=xe.ChildNodes;/繼續(xù)獲取xe子節(jié)點(diǎn)的所有子節(jié)點(diǎn) foreach(XmlNode xn1 in nls)/遍歷 XmlElement xe2=(XmlElement)xn1;/轉(zhuǎn)換類型 if(xe2.Name="pass")/如果找到 xe2.InnerText="66666"/則修改 break; break; xmlDoc.Save(Server.MapPath("user.xml");/保存 /刪出節(jié)點(diǎn) private void

7、 deleteNode() LoadXml(); XmlNodeList xnl=xmlDoc.SelectSingleNode("user").ChildNodes; foreach(XmlNode xn in xnl) XmlElement xe=(XmlElement)xn; if(xe.GetAttribute("name")="發(fā)明") /xe.RemoveAttribute("name");/刪除name屬性 xe.RemoveAll();/刪除該節(jié)點(diǎn)的全部內(nèi)容 break; xmlDoc.Save(S

8、erver.MapPath("user.xml");/保存 private void showIt() LoadXml(); XmlNode xn=xmlDoc.SelectSingleNode("user"); XmlNodeList xnl=xn.ChildNodes; foreach(XmlNode xnf in xnl) XmlElement xe=(XmlElement)xnf; / Console.WriteLine(xe.GetAttribute("name");/顯示屬性值 / Console.WriteLine(xe.GetAttribute(&quo
