Parsing XML to get one bit of information doesn't seem like a great
idea.  If the script needs exact counts then sure, parse away, but if
all it needs to know is whether any are non-zero then what's wrong
with having that reflected in the exit code?  That's far easier for a
script to interpret, and there's plenty of precedent for using exit
codes this way.
