[Exist-open] Self axis error

[Joe W. <jo...@gm...>]

Hi all,

I am getting a strange error in eXide on a simple XPath statement:

  let $x := <x><y/><z/></x>
  return
    $x/y[following-sibling::element()[1]/self::z]

I would expect the results to return <y/> -- since its first
following-sibling element is a z element.  Saxon (embedded in oXygen
15) returns <y/>.

Instead, I get this error: "Cannot compile xquery: err:XPST0005
Self::{}z called on set of nodes which do not contain any nodes of
this name. [at line 3, column 48, source: String]"

Is this a bug in eXist-db?

Thanks,
Joe
