本文介绍了如何获取XML标记的内部文本并将内部文本保存在文本文件中的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

 OpenFileDialog openFileDialog =  new  OpenFileDialog（）; 
 openFileDialog.Multiselect =  true ; 
 openFileDialog.Filter =  文本文件（* .txt）| * .txt |所有文件（*。 。*）| *。*; 
 openFileDialog.InitialDirectory = Environment.GetFolderPath（Environment.SpecialFolder.MyDocuments）; 
  if （openFileDialog.ShowDialog（ this ）== DialogResult.OK）
 {
  string  strFilename = openFileDialog.FileName; 
 XmlDocument xmlDoc =  new  XmlDocument（）; 
  if （File.Exists（strFilename））
 {
 xmlDoc.Load（strFilename）; 
  string  xmlFile = File.ReadAllText（strFilename）; 
 XmlDocument xmldoc =  new  XmlDocument（）; 
 xmldoc.LoadXml（xmlFile）; 
 XmlNodeList nodeList = xmldoc.GetElementsByTagName（  coordinates）; 
  string  coordinates =  string  .Empty; 
  foreach （ nodeList中的XmlNode节点）
 {
 coordinates = node.InnerText; 
  string  [] lst = coordinates.Split（  .ToCharArray（））; 
  foreach （ string  str  in  lst）
 {
 coordinates + = str + Environment.NewLine; 
} 
} 
 
 SaveFileDialog savefile =  new  SaveFileDialog（）; 
 savefile.Filter =  文本文件（* .txt）| * .txt |所有文件（*。 。*）| *。*; 
  if （savefile.ShowDialog（）== DialogResult.OK）
 {
 使用（StreamWriter sw =  new  StreamWriter（savefile.FileName））
 {
 sw.WriteLine（coordinates）; 
 sw.Flush（）; 
} 
} 
} 
}





从解决方案中添加XML 1

输入XML：

什么我试过了：



此代码获得的o / p是

但在此之前我不需要以水平方式获得最高价值，有人可以帮我纠正代码以这种方式获取o / p请

o / p：

解决方案

这是一种方法



 XNamespace xns =   http://www.opengis.net/kml/2.2; 
 XDocument xdInput = XDocument.Load（ @  C：\Temp \ input.xml）; 
 XElement xeDocument = xdInput.Root.Element（xns +   Document）; 
 XElement xePlaceMark = xeDocument.Element（xns +   Placemark）; 
 
 XElement xeCoord = xePlaceMark.Descendants（xns +   coordinates）。第一（）; 
 
  string  [] lines = xeCoord.Value.Trim（）。Split（' '）; 
 File.WriteAllLines（ @  C：\Temp\Output.txt，线路）;

What I have tried:

the o/p obtained for this code is
80.4302618226675,14.10146821639644,0 80.42576847769909,14.01560482206596,0 80.42217788625582,13.94694674204649,0 80.41768407455187,13.86119299421783,0 80.39658103437603,13.79361789706296,0 80.39388165361999,13.7422419928809,0 80.390282415801,13.67377041492268,0 80.38305143626342,13.53699640691199,0 80.37760577599572,13.43454151969623,0 80.37397453710747,13.36627494143451,0 80.36943988618303,13.28097184062539,0
80.4302618226675,14.10146821639644,0

80.36943988618303,13.28097184062539,0

you can see here o/p which i actually need to get is this:

80.4302618226675,14.10146821639644,0
80.42576847769909,14.01560482206596,0

80.36943988618303,13.28097184062539,0

but before that i dont need the top most value in horizantal manner,can someone help me to correct the code to obtain me the o/p in this manner please
o/p:
80.4302618226675,14.10146821639644,0

This is one way to do it

XNamespace xns = "http://www.opengis.net/kml/2.2";
XDocument xdInput = XDocument.Load(@"C:\Temp\input.xml");
XElement xeDocument = xdInput.Root.Element(xns + "Document");
XElement xePlaceMark = xeDocument.Element(xns + "Placemark");

XElement xeCoord = xePlaceMark.Descendants(xns + "coordinates").First();

string[] lines = xeCoord.Value.Trim().Split(' ');
File.WriteAllLines(@"C:\Temp\Output.txt", lines);



Output:

80.4302618226675,14.10146821639644,0
