xml 删除节点问题 急等
- XML code
<?xml version="1.0" encoding="utf-8"?><graph xaxisname="51KH.CN" yaxisname="Export" hovercapbg="DEDEBE" hovercapborder="889E6D" rotateNames="0" yAxisMaxValue="600" numdivlines="9" divLineColor="CCCCCC" divLineAlpha="80" decimalPrecision="0" showAlternateHGridColor="1" AlternateHGridAlpha="30" AlternateHGridColor="CCCCCC"> <categories font='Arial' fontSize='11' fontColor='000000'> <category name='3/1' /> <category name='3/2' /> <category name='3/3' /> <category name='3/4' /> <category name='3/5' /> <category name='3/6' /> <category name='3/7' /> </categories> <dataset seriesname='PV' color='FDC12E'> <set value='30' /> <set value='26' /> <set value='29' /> <set value='31' /> <set value='64' /> <set value='34' /> <set value='94' /> </dataset> <dataset seriesname='IP' color='56B9F9'> <set value='67' /> <set value='98' /> <set value='79' /> <set value='73' /> <set value='80' /> <set value='34' /> <set value='134' /> </dataset></graph>
我想删除所有节点
只留下
- XML code
<?xml version="1.0" encoding="utf-8"?><graph xaxisname="51KH.CN" yaxisname="Export" hovercapbg="DEDEBE" hovercapborder="889E6D" rotateNames="0" yAxisMaxValue="600" numdivlines="9" divLineColor="CCCCCC" divLineAlpha="80" decimalPrecision="0" showAlternateHGridColor="1" AlternateHGridAlpha="30" AlternateHGridColor="CCCCCC"></graph>
[解决办法]
- C# code
XmlNodeList xnl = xmlDoc.SelectSingleNode("graph").ChildNodes; foreach (XmlNode xn in xnl) { XmlElement xe = (XmlElement)xn; if (xe.GetAttribute("xaxisname") == "51KH.CN") xe.RemoveAll();//删除该节点的全部内容 } xmlDoc.Save("bookstore.xml");
[解决办法]
- C# code
XmlDocument xmlDoc = new XmlDocument();xmlDoc.Load(System.Web.HttpContext.Current.Server.MapPath("~/Content/Url.xml"));XmlNodeList nodeList = xmlDoc.SelectSingleNode("graph ").ChildNodes;//获取节点集合foreach (XmlNode item in nodeList){//可以判断节点名称 来删除item.RemoveAll();//移除当前节点｝xmlDoc.Save("URL");//保存
[解决办法]
- C# code
XmlDocument doc = new XmlDocument(); doc.Load(@"C:\aaa.xml"); XmlElement rootel = doc.DocumentElement; if (rootel != null) { for (int i = rootel.ChildNodes.Count - 1; i >= 0; i--) { rootel.RemoveChild(rootel.ChildNodes[i]); } doc.Save(@"C:\aaa.xml"); }
