# fn:resolve-QName - XPath XQuery Reference

Returns an xs:QName value (that is, an expanded-QName) by taking an
               xs:string that has the lexical form of an xs:QName (a
            string in the form "prefix:local-name" or "local-name") and resolving it using the
            in-scope namespaces for a given element.deterministiccontext-independentfocus-independentIf $qname is the empty sequence, returns the empty sequence.More specifically, the function searches the namespace bindings of $element
            for a binding whose name matches the prefix of $qname, or the zero-length
            string if it has no prefix, and returns an expanded-QName whose local name is taken
            from the supplied $qname, and whose namespace URI is taken from the string
            value of the namespace binding.If the $qname has no prefix, and there is no namespace binding for
               $element corresponding to the default (unnamed) namespace, then the
            resulting expanded-QName has no namespace part.The prefix (or absence of a prefix) in the supplied $qname argument is
            retained in the returned expanded-QName, as described in .Assume that the element bound to $element has a single namespace binding
               bound to the prefix eg.fn:resolve-QName("hello", $element) returns a QName with local name
               "hello" that is in no namespace.fn:resolve-QName("eg:myFunc", $element) returns an xs:QName
               whose namespace URI is specified by the namespace binding corresponding to the prefix
               "eg" and whose local name is "myFunc".A dynamic error is raised  if $qname does
            not have the correct lexical form for an instance of xs:QName.A dynamic error is raised  if $qname has
            a prefix and there is no namespace binding for $element that matches this
            prefix.Sometimes the requirement is to construct an xs:QName without using the
            default namespace. This can be achieved by writing: if (contains($qname, ":")) then fn:resolve-QName($qname, $element) else
            fn:QName("", $qname)If the requirement is to construct an xs:QName using the namespaces in the
            static context, then the xs:QName constructor should be used.
