Document fragments, how to?

Hi there,

My XML document stored in Tamino is huge, and can grow really big. I am trying to get a fragment of the document, insert a few nodes and then store back just that little piece; or if possible just call something like:

whatever.insert ( XPath, Node )

or better:

whatever.update ( XPath, Node )

Is there any way to do that? I tried using accessor.update(xmlobject) but it thinks I am updating the whole document where xmlobject is just the fragment I queried before. Any ideas?

Thanks in advance,
