Question

do you know to do XQuery query for selection of content between two singleton tags, e.g.

<pb n="1"/>
   this is <foo>page</foo> number one
<pb n="2"/>
   this is <bar>page</bar> number two
<pb n="3"/>
   this is <x>page</x> number three

and I want for example content of second page, so between <pb n="2"/> and next <pb/>. Output should be then:

   this is <bar>page</bar> number two

Answer 1

You can do this using following-sibling together with the << operator, like this:

let $xml := <xml>
<pb n="1"/> 
   this is <foo>page</foo> number one 
<pb n="2"/> 
   this is <bar>page</bar> number two 
<pb n="3"/> 
   this is <x>page</x> number three 
</xml>
return
  $xml/pb[2]/following-sibling::node()[. << $xml/pb[3]]

HTH!
