.net操作带命名空间的xml(仅列一个获取节点值的例子其他以此类推)

公司项目需要,需要在WebServices中处理一些xml格式数据

但这些xml数据带有命名空间(xmlns)

刚开始Origami不懂,走了一些弯路,现在总结下~

附相关代码:

using System; using System.Data; using System.Configuration; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; using System.Xml; using System.IO;

namespace webservice {     public class verify     {         private string result = "";         private XmlDocument xmlDoc;         public string GetChinaHRXml(string inputXml)         {             string ATSLinkIDs = "";             string finallyXml = "";             LoadXML(ref xmlDoc, inputXml);             XmlNamespaceManager namespaceManager = new XmlNamespaceManager(xmlDoc.NameTable);             namespaceManager.AddNamespace("aa", "命名空间URL(即xmlns=后边的url)");             XmlElement node = (XmlElement)xmlDoc.SelectSingleNode("/aa:Query/aa:QueryCondition/aa:QueryJob", namespaceManager);             if (node != null)             {                 ATSLinkIDs = node.InnerText;                 node = null;             }             xmlDoc.SelectSingleNode("/aa:Query/aa:QueryCondition/aa:QueryJob", namespaceManager).InnerText = "";             finallyXml = xmlDoc.OuterXml;             xmlDoc = null;             return finallyXml;         }         public void LoadXML(ref XmlDocument ixmlDoc, string strXML)         {             ixmlDoc = new XmlDocument();             ixmlDoc.LoadXml(strXML);         }     } }

仅有一个获取值的例子,其他修改或者删除参考下边这个转载的没有操作命名空间的xml的代码

        //修改节点         private void UpdateElement()         {             LoadXml();             XmlNodeList nodeList=xmlDoc.SelectSingleNode("user").ChildNodes;//获取bookstore节点的所有子节点             foreach(XmlNode xn in nodeList)//遍历所有子节点             {                 XmlElement xe=(XmlElement)xn;//将子节点类型转换为XmlElement类型                 if(xe.GetAttribute("name")=="风云")//如果name属性值为“风云”                 {                     xe.SetAttribute("name","发明");                     //如果下面有子节点在下走                      XmlNodeList nls=xe.ChildNodes;//继续获取xe子节点的所有子节点                     foreach(XmlNode xn1 in nls)//遍历                     {                        XmlElement xe2=(XmlElement)xn1;//转换类型                         if(xe2.Name=="pass")//如果找到                         {                             xe2.InnerText="66666";//则修改                             break;                         }                     }                     break;                 }             }            xmlDoc.Save(Server.MapPath("user.xml"));//保存         }

        //删出节点         private void deleteNode()         {             LoadXml();             XmlNodeList xnl=xmlDoc.SelectSingleNode("user").ChildNodes;             foreach(XmlNode xn in xnl)             {                 XmlElement xe=(XmlElement)xn;                                 if(xe.GetAttribute("name")=="发明")                 {                     //xe.RemoveAttribute("name");//删除name属性                    // xe.RemoveAll();//删除该节点的全部内容                     xe.ParentNode.RemoveChild(xe);                                         break;                 }             }             xmlDoc.Save(Server.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"));//显示属性值 //                Console.WriteLine(xe.GetAttribute("sex")); // //                XmlNodeList xnf1=xe.ChildNodes; //                foreach(XmlNode xn2 in xnf1) //                { //                    Console.WriteLine(xn2.InnerText);//显示子节点点文本 //                }             }         } 原文:.net操作带命名空间的xml(仅列一个获取节点值的例子其他以此类推)
