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

Hello Rob,

no, this not a bug. replace() uses regex for its pattern and as the path has {} and [] in them they will be interpreted as regex. You could write your own replace function or something trivial (but quite limited) like using substring and string-length, e.g.:

substring(path($b), string-length(path($a)) + 1)

Cheers, Dirk

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
