Linq à Xml noob question

Question

J'essaye d'analyser un mvcSiteMap, j'ai la plupart du travail, mais ma clause où il n'est pas bon. il renvoie toujours la ligne que la clause where doit exclure.

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(); 

Je reçois le même nombre de lignes renvoyées que la clause where soit présente ou non. c'est comme si la clause where est toujours vraie, même si l'élément title de la sortie lsit contient "Bulk Order Request" comme son titre

Je suis sûr que je fais quelque chose d'obvioulsy stupide, mais je ne peux pas le voir.

Merci,

réécrite non lambda fonctionne très bien

  XElement xelement2 = XElement.Load(filePath); 

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