text: Q:
  
  string in xpath
  
  I have a string and I want to use  it as a selector in xpath to select a node with name as value of the string.
  declare variable $get_count := <count><comedy>1</comedy></count>;
  (: $string = "comedy" :)
   let $value =  $get_count/$string (: but this doesn't return anything)
  
  How shall i do it?
  
  A:
  
  let $value =  $get_count/$string (: but this doesn't return anything) 
  
  Use:
  declare variable $get_count := <count><comedy>1</comedy></count>;
  declare variable $string := "comedy";
  
   let $value :=  $get_count/*[name()=$string]
    return 
      $value
  
  When this is applied on any XML document (not used), the wanted, correct result is produced:
  <comedy>1</comedy>
