Convert XPath to LINQ

Question

Working with an XML file in C #, I'm trying to convert an XPath query to LINQ, and I don't know how to reach the last section:

XPath:

variable.XPathSelectElements("procedures/menu[@id='value']/procedure[@id]") 

LINQ:

 from el in variable.Descendants("procedures").Descendants("menu") where el.Element("id").Value == "value" 

How do I execute the / procedure [@id] section?

I changed your @Jon sentence, but I seem to be making a simple mistake here that I cannot solve.

 XDocument doc = XDocument.Load("procedures.xml"); var query = doc.Elements("procedures") .Elements("menu") .Where(x => (string) x.Attribute("id") == "value") .Elements("procedure").Where(x => x.Attribute("id") != null); public List<string> commands = new List<string>(); foreach (XElement procedure in query) { commands.Add(procedure.Attribute("id")); } 

Answer 1

/procedure[@id] selects all elements of the "procedure" that have the attribute "id". However, I do not believe that you should use Descendants in this case. I believe your request should really be:

  variable.Elements("procedures") .Elements("menu") .Where(x => (string) x.Attribute("id") == "value") .Elements("procedure") .Where(x => x.Attribute("id") != null); 

EDIT: There is an easier way to get the command identifiers into a list:

 XDocument doc = XDocument.Load("procedures.xml"); var commands = doc.Elements("procedures") .Elements("menu") .Where(x => (string) x.Attribute("id") == "value") .Elements("procedure") .Where(x => x.Attribute("id") != null) .Select(x => x.Attribute("id").Value) .ToList();
