我有下面的XML元素获取过滤：

<?xml version="1.0" encoding="utf-8"?>

    <assertion id="SLM_CekNonNegative">

     <unsatisfied count="4">

我怎样才能得到的<assertion id="SLM_CekNonNegative">这是SLM_CekNonNegative价值？

下面是我到目前为止的代码：

string pathasr = @"D:\HARPITNAS\dari mbak julia\logs\123456789-2012-09-30-BSMS10.xml-assertions2.xml"; 
List<string> msg = new List<string>(); 
XmlDocument doc = new XmlDocument(); 
doc.Load(pathasr); 

foreach (XmlNode node in doc.DocumentElement) 
{ 
    string thevaluethatiwantvariable = string.Empty; 
    thevaluethatiwantvariable = ? ; 

    if (node.LastChild.HasChildNodes == true) 
    { 
      string count = node.LastChild.ChildNodes.Count.ToString(); 
      foreach (XmlNode y in node.LastChild.ChildNodes) 
      { 
       string masg = y.InnerXml; 
       msg.Add(masg); 
      } 
    } 
} 

此代码不会得到我想要的价值。当我调试它时，我可以看到它没有得到正确的值。有可能获得我想要的价值吗？

Answer 1

thevaluethatiwantvariable = doc.DocumentElement.SelectSingleNode("//assertion[@name = 'id']/@value").Value;

Answer 2

而不使用XPath这将是这样的：

string theValue = doc.DocumentElement["assertion"].Attributes["id"].Value; 

而且也没有必要对任何类型的循环。
