If I reformat your stylesheet (which somehow got

causes you trouble (because an xsl:stream without a sequence
constructor
does nothing), or is it the one without the commented-out part?
It is also important to try to find out what is actually causing the
memory
exception. If you run it from oXygen like you say, it is very
well possible
that the exception comes from oXygen itself, not capable
of handling the
output file. This would explain the late memory
exception. To find this out,
simply run it from the command line, and
what what happens to memory in task
manager.

wanted to do to see if I could get to the end of the file. After about 45
minutes it hits my memory limit and quits. Am I doing this right or will I
need to cut this elephant into pieces?

Abel,
I am running
the saxon ee version inside Oxygen. I don't have a license for ee outside of
Oxygen. I commented out the sequence constructor inside xsl:stream to see if
that was causing me the problem and I did get a message after the
out-of-memory that I should not expect any output.
