本文實例講述了asp.net實現輸出xml的方法。分享給大家供大家參考，具體如下：
#region 根據xml節點 查詢xml節點的值并作修改/// <summary>/// 根據xml節點 查詢xml節點的值并作修改/// </summary>/// <param name="fileName">要加載的xml文件</param>/// <param name="tagName">xml節點的名稱</param>/// <param name="newXmlText">修改后的值</param>/// <returns></returns>public void GetXmlbySelNodel(string fileName, string selNodeName, string tagName,string newXmlText){ try { doc.Load(Server.MapPath(fileName)); XmlNodeList nodelist = doc.DocumentElement.SelectSingleNode(selNodeName).ChildNodes; foreach (XmlNode node in nodelist) { XmlElement xle = node as XmlElement; XmlNodeList list = xle.ChildNodes; for (int j = 0; j < list.Count; j++) { if (xle.ChildNodes[j].Name == tagName) { xle.ChildNodes[j].InnerText = newXmlText; SaveXml(fileName); break; } } } } catch { }}#endregion#region 保存修改后xml文件內容//保存修改后xml文件內容public void SaveXml(string fileName){ doc.Save(Server.MapPath(fileName));}#endregionstring selNodeName="//url/data";string fileName = "meituanAPI.xml";GetXmlbySelNodel(fileName, selNodeName, "website", "腳本之家");GetXmlbySelNodel(fileName, selNodeName, "siteurl", "www.49028c.com");GetXmlbySelNodel(fileName, selNodeName, "city", "杭州");GetXmlbySelNodel(fileName, selNodeName, "tip", "送ipad 抽獎!!");GetXmlbySelNodel(fileName, "//data/shops", "name", "上海洲信 信息技術有限公司!");DataSet ds = new DataSet();ds.ReadXml(Server.MapPath("meituanAPI.xml"));XmlTextWriter writer = new XmlTextWriter(Response.OutputStream, Response.ContentEncoding);ds.Tables[0].WriteXml(writer);Response.ContentType = "text/xml;charset=gb2312";Response.Flush();Response.End() 或者
Response.ClearContent();Response.ClearHeaders();Response.contentType="application/xml"';Response.WriterFile(Server.Mappath("API/54tuanAPI.xml"));Response.Flush();Response.End(); 希望本文所述對大家asp.net程序設計有所幫助。
