Saxon

I'm trying to do a streaming transform, but accumulators don't seem to be working. I'm trying to convert some XML to tabular format (like CSV). I'm trying to pull out the child text content of a bunch of sibling elements and emit them in an order different from the source XML. It seems like accumulators are the simplest approach for this, but it's not working for me.

I'm using this sample XML:

   
      Gambardella, Matthew
      <title>XML Developer's Guide</title>
      Computer
      44.95
      2000-10-01
      An in-depth look at creating applications 
      with XML.
   
   
      Ralls, Kim
      <title>Midnight Rain</title>
      Fantasy
      5.95
      2000-12-16
      A former architect battles corporate zombies, 
      an evil sorceress, and her own childhood to become queen 
      of the world.
   

I'm using this sample XSLT:

   

   

   
      
   

   
   
      
      dummy
      ,
      ,

   

   
   id,title,author,price,publish_date

If I run it with the streamable="yes" commented out, then I get what I'd expect:

id,title,author,price,publish_date
bk101,
      XML Developer's Guide,

   bk102,
      Midnight Rain,

(Yes the formatting is wonky and I'm only pulling one field, but this is proof-of-concept and demonstates the problem.)

If I run it with the streamable="yes" commented in, I get nothing in the accumulator:

id,title,author,price,publish_date
bk101,
      ,

   bk102,
      ,

So it seems like my approach is valid but Saxon is not doing the right thing in steam mode. (I'm using SaxonEE9-5-1-2J.) The only thing I've been able to get to stick in the accumulator is the element name ("title").

What am I doing wrong? Is this the approach you would recommend for this task?
