从上面我需要提取燃料类型“核”的所有项目，并比较“输出”或“能力”值与前一小时相比是否发生变化。

我需要按照严格的说明使用正则表达式提取所有数据。

使用正则表达式<Hour[^>]*?>(?<Value1>.*?)</Hour>

从“值”组中，我可以获得小时的值，它为每个生成器名称提供 1、2、3、4、5、6、1、2、3、4、5、6 等输出，但由于没有小时是我所需要的，我只需要一次，也就是说我应该只获得一次 1,2,3,4,5,6

请帮我解决一下这个。

不，您不使用正则表达式来解析 XML..即使它是使用它的严格说明也不行.. 说真的，那是谁！

XDocument doc=XDocument.Load(PATH);

var generatorsList=
doc.Descendants("Generator")
   .Where(x=>x.Element("FuelType").Value=="NUCLEAR")
   .Select(y=>new
   {
       GeneratorName=y.Element("GeneratorName").Value,
       OutputHours=y.Element("Outputs").Descendants("Hour").Select(h=>int.Parse(h.Value)).ToList(),
       CapabilityHours=y.Element("Capabilities").Descendants("Hour").Select(h=>int.Parse(h.Value)).ToList()

   });

现在你可以迭代generatorsList

foreach(var generator in generatorsList)
{
    generator.GeneratorName;
    foreach(int hour in generator.OutputHours);
    foreach(int hour in generator.CapabilityHours);
}

I got the solution for my query you can achieve it with the help of regex. In order to get the value of EnergyMW under capability tag i came up with following regex:
 (<Capability>[^<]+?).+?(<EnergyMW>(?<Value>.*?)<\/EnergyMW>\n)(</Capability>)
 using this expression with RegexOptions.Singleline the target is achieved.
