Linq to Xml noob question

Question

Я пытаюсь разобрать mvcSiteMap, у меня есть большая часть его работы, но моя там, где это не так. он всегда возвращает строку, которую должно исключать предложение where.

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(); 

Я получаю такое же количество возвращенных строк, существует ли предложение where или нет. это как предложение where всегда верно, даже если элемент заголовка выведенного lsit содержит «Bulk Order Request» как его заголовок

Я уверен, что я делаю что-то Obvioulsy глупо, но я не могу видеть это.

Спасибо,

переписаны это не лямбда работает отлично

  XElement xelement2 = XElement.Load(filePath); 

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