[basex-talk] relative path between two element in xquery

15 Aug 2014

      Hi,

How can I construct the relative path between two elements in an xml-file.

Most probably overlooking the obvious I ended up with the solution below,
which, unfortunately, triggers an runtime-error.

My not-working solution:

let $xml := 

  <xml>

    <A>

      <B/>

    </A>

  </xml>

let $b   := $xml//B

let $a   := $xml//A

return replace( string( path( $b))

                             , string( path( $a))

                             , ''

                            )

Two questions:

-          How to retrieve the relative path between two element within a
xml-file?

-          Why does the solution above trigger an error? Can it be a bug? (
oops, three questions)

Thnx in advance for the reply,

Rob Stapper
