Question

我尝试过搜索答案，但没有找到解析这一段文本的正确方法：

<Hotspot X="-8892.787" Y="-121.9584" Z="82.04719" />
<Hotspot X="-8770.094" Y="-109.5561" Z="84.59527" />
<Hotspot X="-8755.385" Y="-175.0732" Z="85.12362" />
<Hotspot X="-8701.564" Y="-114.794" Z="89.48868" />
<Hotspot X="-8667.162" Y="-122.9766" Z="91.87251" />
<Hotspot X="-8802.135" Y="-111.0008" Z="82.53865" />

我想将每一行输出到：

Ex. X="-8892.787" Y="-121.9584" etc...

Answer 1

如果您可以将其视为XML，那么这将是更好的方式，因此，请考虑将其视为：

<Hotspots>
  <Hotspot X="-8892.787" Y="-121.9584" Z="82.04719" />
  <Hotspot X="-8770.094" Y="-109.5561" Z="84.59527" />
  <Hotspot X="-8755.385" Y="-175.0732" Z="85.12362" />
  <Hotspot X="-8701.564" Y="-114.794" Z="89.48868" />
  <Hotspot X="-8667.162" Y="-122.9766" Z="91.87251" />
  <Hotspot X="-8802.135" Y="-111.0008" Z="82.53865" />  
</Hotspots>

将其加载到XmlDocument中，然后按如下方式解析：

var xml = "<Hotspots><Hotspot X=\"-8892.787\" Y=\"-121.9584\" Z=\"82.04719\" /></Hotspots>";
XmlDocument doc = new XmlDocument();
doc.LoadXml(xml);

foreach (XmlNode item in doc.SelectNodes("/Hotspots/Hotspot"))
{
    Console.Write(item.Attributes["X"].Value);
    Console.Write(item.Attributes["Y"].Value);
    Console.Write(item.Attributes["Z"].Value);

    // And to get the ouput you're after:
    Console.Write("X=\"{0}\" Y=\"{1}\" Z=\"{2}\"", 
                  item.Attributes["X"].Value, 
                  item.Attributes["Y"].Value, 
                  item.Attributes["Z"].Value);
}

注意：我在var xml = "..."中使用了一个简化示例，使其更具可读性

我猜你对你的开发技巧不太了解，但这不仅仅是文本，它是xml，你可以使用Linq To XML以这样的方式轻松访问它：

XDocument myXDoc = XDocument.Parse(string.Format("<?xml version=\"1.0\" encoding=\"utf-8\"?><root>{0}<root>", yourXmlString));
foreach (XElement hotspot in myXDoc.Root.Elements())
{
    Console.WriteLine(string.Format("X=\"{0}\" Y=\"{1}\"", hotspot.Attribute("X").Value, hotspot.Attribute("Y").Value));
}

我会在XML和Linq To XML上阅读：

假设每一行都以<Hotspot ...

开头

//Lines are read into (for this example) a string[] called lines
List<string> valueLines = new List<string>();

foreach(string l in lines)
{
  string x;
  string y;
  string z;

  int xStart = l.IndexOf("X");
  int yStart = l.IndexOf("Y");
  int zStart = l.IndexOf("Z");
  int closeTag = l.IndexOf(@"/");

  StringBuilder vlBuilder = new StringBuilder();

  vlBuilder.Append(l.Substring(xStart, (yStart - xStart - 1));
  vlBuilder.Append(l.Substring(yStart, (zStart - yStart - 1));
  vlBuilder.Append(l.Substring(zStart, (closeTag - zStart - 1));

  valueLines.Add(vlBuilder.ToString());
}
