If you're coding in Java I'd suggest xmlbeans. I've found xmlbeans fast, easy, quick to employ; very handy in about half a dozen projects now.
This suggestions seems to be extreme overkill as you're not even interested in the contents of the invoices.
In terms of performance, I would expect StAX and SAX to be roughly equal. Something hardcoded that is not XML-aware will be a lot faster, but much more error-prone.

You need to compile the schema which returns java code that will then allow you to directly reference any element. Then, simply reference the invoice structure's topmost element, and then do as you wish, either write the xml to the queue as simple text, or create a new xml document (just provides the xml header at the start of the file) and add only this copied element to it and write to the queue, or strip all or selected, etc..., etc..., and write to the queue and iterate to the next invoice or batch file. It could be 20 lines of code tops.
If you don't have a schema to feed into the schema compiler there are a couple of tools that you can build a schema and a couple that infer schema from sample xml.

Hi
I have a particular problem to solve:
I have an xml batch file that contains individual xml invoices. I need to
extract these xml invoices one at a time and
place them on a message queue i.e. I just need to get all the data between
the invoice start and end tags put it
in a string and place it on a message queue (validation occurs on the
invoice itself on the receiver side).
What is likely to be my best approach, DOM (unlikely I guess), SAX, StAX or
simply writing a java program using indexOf, in terms of performance ?
TIA Peter
