Eventually went with reverse data order as it was not much more difficult.

Done, though the process requires xslt and Perl, as I could not work
out how to create a running total in XSLT.

Also the output is in increasing date order and includes one entry for
each distinct start/end date.
Not sure what dates were use originally as they don't all seem to
appear in podlings.xml.

The final total is 1 different from before, but agrees with podlings.xml

Just realised that apsite won't be able to commit the generated output.
