如何刷新我的xml文档

问题描述

实际上我将文本字段数据加载到xml文件中
但是当我下次执行程序时，它将把我的文本字段数据附加到我不想要的xml文件中.我希望下次xml存储新数据时，不要将该数据附加到以前的数据中

我的代码是:-

XmlDocument xmldoc =新的XmlDocument();
xmldoc.Load(@"E:\\ grabone1 \\ grabone1 \\ Insert.xml");
XmlNode节点= xmldoc.SelectSingleNode("records");
XmlNode recordnode = node.AppendChild(xmldoc.CreateNode(XmlNodeType.Element，"reocord"，")));
recordnode.AppendChild(xmldoc.CreateNode(XmlNodeType.Element，"tlpl06m"，")).InnerText = txttplm.Text;
recordnode.AppendChild(xmldoc.CreateNode(XmlNodeType.Element，"tlpl06f"，")).InnerText = txttplf.Text;
recordnode.AppendChild(xmldoc.CreateNode(XmlNodeType.Element，"tlpl06"，")).InnerText = txttpltotal.Text;
recordnode.AppendChild(xmldoc.CreateNode(XmlNodeType.Element，"catagory"，")).InnerText = txtcatgory.Text;

xmldoc.Save(@"E:\\ grabone1 \\ grabone1 \\ Insert.xml");

解决方案

actually i load my text field data into a xml file
but when i execute my programe next time it will append my text field data into xml file which i dont want .i want that next time xml store new data not append that data in to previous data

my code is:-

XmlDocument xmldoc = new XmlDocument();
xmldoc.Load(@"E:\\grabone1\\grabone1\\Insert.xml");
XmlNode node = xmldoc.SelectSingleNode("records");
XmlNode recordnode=node.AppendChild(xmldoc.CreateNode(XmlNodeType.Element,"reocord",""));
recordnode.AppendChild(xmldoc.CreateNode(XmlNodeType.Element, "tlpl06m", "")).InnerText = txttplm.Text;
recordnode.AppendChild(xmldoc.CreateNode(XmlNodeType.Element, "tlpl06f", "")).InnerText = txttplf.Text;
recordnode.AppendChild(xmldoc.CreateNode(XmlNodeType.Element, "tlpl06", "")).InnerText = txttpltotal.Text;
recordnode.AppendChild(xmldoc.CreateNode(XmlNodeType.Element, "catagory", "")).InnerText = txtcatgory.Text;

xmldoc.Save(@"E:\\grabone1\\grabone1\\Insert.xml");

解决方案

Perhaps you need to RTFM. You append a node, but you don''t want to do that ? I''d use an XmlTextWriter to simplify just overwriting your current document. Then I''d read a book and learn something instead of copying code at random over the web and getting confused when it does what you ask it, instead of what you hoped it might.
