我想要获得的是
<EndTest 
Title="GetMessageName1ArgTest" 
Result="Pass" >
</EndTest>
同时 result="fail"

------解决方案--------------------

C# code

 string XPath = "/WTT-Logger/EndTest[@title='?']";
 System.Xml.XmlDocument doc = new System.Xml.XmlDocument();

        doc.Load((HttpContext.Current.Server.MapPath(filepath)));
        System.Xml.XmlNode node = doc.SelectSingleNode((XPath.Replace("?", "GetMessageName1ArgTest")));
//这里的node就是要的
//下面是属性
        node.Attributes["result"].InnerText;
