Selecting all text nodes in between two processing instructions with XPATH

Question

I have some following XML:

  

    
    test 
    test
    test         


        

Answer 1

I recommend using xal:for-each-group as suggested in the first comment by Maring Honnen. The other XPath approaches allow you to select the content between two processing instructions, but it will be hard to embed that in an xslt stylesheet that should do other things as well, like copying existing structure at the same time. Here a minimal approach using for-each-group:

xquery version "1.0-ml";

let $xml :=
  
    

      before
      
      test 
      test
      test
      
      after
    
  

let $xsl :=
  

    
      
        
      
    

    
      

      
        
          
            
              
            
          

          
            
          
        
      
    

  

return xdmp:xslt-eval($xsl, $xml)

Use a second for-each-group with group-ending-by as suggested by Martin if you like to get the end PI inside the tag. The above might be sufficient though.

HTH!
