Thanks!

I finally got it working, but one thing is missing: the attributes of
the elements. I absolutely cannot miss the atributes, as I use them in
my XSLT to construct an HTML file. This is my entire XQuery script (I
hope it is useful for someone else as well):

declare namespace readme = "readme";

declare function readme:processNode($e as node()) as node()* {
   let $path := readme:getXPath($e)
   return
      if($path = "path")
      then (
         for $c in $e
            return
               <d>
               <SELECT />
               <SELECT2> {$e}</SELECT2>
               </d>
      )
      else (
         typeswitch ($e)
         case element()
         return
         element {name($e)} {
         for $c in $e/child::node()
            return
               readme:processNode($c)
         }
         default return $e
      )
};

declare function readme:getXPath ( $node as node() ) as xs:string
{
    let $pathelements := for $a in $node/ancestor-or-self::*
    return
        if ( name($a) = "ead" ) then "/ead[1]"
        else concat(name($a), "[" ,
          count($a/preceding-sibling::*[name()=name($a)]) + 1, "]")
    return string-join( $pathelements, "/" )
};

for $item in doc("file.xml")/*
return
readme:processNode($item)


How do I include the attributes? I know something needs to be changed
in this line of the function processNode:

element {name($e)} {

I am not 100% familiar with the syntax of XQuery yet, so if someone
can help me out...

Thank you,
