asp.net實現輸出xml的方法_實用技巧

本文執行個體講述了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節點的值並作修改/// <summary>/// 根據xml節點 查詢xml節點的值並作修改/// </summary>/// <param name="fileName">要載入的xml檔案</param>/// <param name="tagName">xml節點的名稱</param>/// <param name="newXmlText">修改後的值</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 儲存修改後xml檔案內容//儲存修改後xml檔案內容public void SaveXml(string fileName){  doc.Save(Server.MapPath(fileName));}#endregionstring selNodeName="//url/data";string fileName = "meituanAPI.xml";GetXmlbySelNodel(fileName, selNodeName, "website", "雲棲社區");GetXmlbySelNodel(fileName, selNodeName, "siteurl", "www.jb51.net");GetXmlbySelNodel(fileName, selNodeName, "city", "杭州");GetXmlbySelNodel(fileName, selNodeName, "tip", "送ipad 抽獎!!");GetXmlbySelNodel(fileName, "//data/shops", "name", "上海洲信 資訊技術有限公司!");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程式設計有所協助。
