i have xml.

i cant change xpath. anyway result using same xpath '/a/b'?

you can create document node if need to

let $a := <a>              <b>asd</b>              <c>bvn</c>           </a> let $a := document{$a} return $a/a/b

or directly

let $a := document {             <a>                 <b>asd</b>                 <c>bvn</c>             </a>             }  return $a/a/b
