xml - How to select an attribute using nodesForXPath (NSXMLDocument) -

I want to select XML element using Xpath in an XML document.

My XML document is an example of NSXMLDCast. Here is an example of an XML document:

  & lt; Rootnode & gt; & Lt; Mynode myattrib = "getMe" & gt; & Lt; / Mynode & gt; & Lt; / Rootnode & gt;   
 My XPath is something like this:  
  // mynode @ myattrib   
 this value is "getMe" according:).  
 When I try to:  
  [xmlDoc nodesforx path: @ "// mynode @ myattrib" error: & amp; Error] ;   
 I get the following error:  
  NSLog (@ "% @", error);   
 Output:  
  XQueryError: 3 - "Invalid token (@) - // mynode @ myattrib" in line: 1   
 What should I change to do this work? Is the  @  symbol used in any other way?   
 
 
 Add the first slash @ as:  
  // mynode / @ Myattrib
