I'm sorry for this confusing error message, but I think you got the namespace
URI wrong in your document.

Take a look at the partial-unmarshal example. Also, combining JAXB with
upcoming StAX (JSR-173) would probably lets you do this fairly easily.
If you want to try that today, go to
http://www.xmlpull.org
The idea is that you read through a pull-parser (or SAX events) and send
them to the writer, and when you hit the real meat, you bind that region
to JAXB, do the processing, write them back, then you copy the rest of
the input to the output.
Given the number of questions on this topic, perhaps this might deserve
its own sample.

Using XPath would rob the whole point since it requires a whole document
to be present on memory.
