这是XML文件。我需要以这种方式从该文件中获取坐标值80.41501791166907,15.31966921785412 80.66681262872422,15.30770770315245 81.04469571795477,15.27884283211159

我使用的代码未显示错误，但运行时返回null异常
private void button33_Click_1(object sender, EventArgs e)
{
DialogResult result = openFileDialog1.ShowDialog();
if (result == DialogResult.OK)
{
DialogResult result2 = folderBrowserDialog1.ShowDialog();
if (result2 == DialogResult.OK)
{
ZipFile.ExtractToDirectory(openFileDialog1.FileName, folderBrowserDialog1.SelectedPath);
MessageBox.Show("ZIP file extracted successfully!");
}
}
OpenFileDialog openFileDialog = new OpenFileDialog();
openFileDialog.Multiselect = true;
openFileDialog.Filter = "Text files (*.txt)|*.txt|All files (*.*)|*.*";
openFileDialog.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
if (openFileDialog.ShowDialog(this) == DialogResult.OK)
{
XNamespace xns = "http://www.opengis.net/kml/2.2";
XDocument xdInput = XDocument.Load(openFileDialog.FileName);
XElement xeDocument = xdInput.Root.Element(xns + "Document");
XElement xePlaceMark = xeDocument.Element(xns + "Placemark");
XElement xeCoord = xePlaceMark.Descendants(xns + "coordinates").First();
// string[] lines = Regex.Split(xeCoord.Value, @"\,\0,\ ");
string[] lines = xeCoord.Value.Trim().Split(new string[] {",0 "}, StringSplitOptions.RemoveEmptyEntries);
/* File.WriteAllLines(@"C:\Temp\Output.txt", lines);
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 (XmlNode node in nodeList)
{ coordinates = node.InnerText;
string[] lst = coordinates.Split(" ".ToCharArray());
foreach (string str in lst)
{
coordinates += str + Environment.NewLine;
}
}*/
SaveFileDialog savefile = new SaveFileDialog();
savefile.Filter = "Text files (*.txt)|*.txt|All files (*.*)|*.*";
if (savefile.ShowDialog() == DialogResult.OK)
//{ using (StreamWriter sw = new StreamWriter(savefile.FileName))

假设XML文件的格式正确，则下面的内容应该可以帮助您提取所需的数据并将它们逐行插入文本文件中。
string pathToXmlFile = "";
XDocument document = XDocument.Load(pathToXmlFile);
var coordinates = document.Descendants("coordinates");
string pathToTextFile = "";
StreamWriter streamWriter = new StreamWriter(pathToTextFile);
foreach (XElement coordinate in coordinates)
{
streamWriter.WriteLine(coordinate.Value);
Console.WriteLine(coordinate.Value);
}
streamWriter.Close();
