Linq到Xml noob問題

Question

我試圖解析一個mvcSiteMap，我已經得到了大部分的工作，但我的where子句它不正確。它總是返回where子句應該排除的行。

nodeTitle = "Bulk Order Request"; 

XElement xelement2 = XElement.Load(filePath); 
var urlDescList1 = (xelement2.Descendants() 
    // Select node with 'Favorite Social Sites' 
    .Where(node => (string) node.Attribute("title").Value != nodeTitle) 
    .SelectMany(node => node.Elements()) 
    .Select(node => new 
    { 
     title = node.Attribute("title").Value, 
     url = node.Attribute("action").Value 
    })).ToList(); 

無論where子句是否存在，我都得到相同數量的行返回。 這就像在where子句永遠是真實的，即使輸出lsit的標題元素包含「批量訂單需求」作爲其稱號

我知道我在做什麼Obvioulsy愚蠢的，但我不能看見。

感謝，

重寫了它的非拉姆達工作正常

  XElement xelement2 = XElement.Load(filePath); 

      var query = from c in xelement2.Descendants() 
      where (string)c.Attribute("title").Value != nodeTitle 
      select c;
