Andy,

when i am back from travel i will check this in details but in general 
you should use builder.newDocument() (XmlInfosetBuilder)

then if you want process a fragment you can use XmlPullParser - position 
it on STAR_TAG for fragment and call builder.parseFragment() then you 
should be able to run XPath on this fragment, when you are finished with 
this chunk XML move to next.

i believe that should allow you to get through very large XML documents 
by processing it in chunks and be able to do XPath on each chunk.

is it what you want to do?
