lorem ipsum surely?

Anyway there appears to be a problem with your pipeline.

Quote:

gunzip path/filename.pages | cat index.xml | xsltproc path/index.xsl | wc -w

If we assume that you are processing a file called "index.xml" from the archive filename.pages, we need to remove one of the pipe characters. Then the pipeline makes sense. We can then adjust the total (assuming that the faulty pipeline was not giving you wrong figures by reading "index.xml" before gunzip finished).
My guess at the pipeline may be flawed - see below.

Code:

gunzip path/filename.pages
words_total=`cat index.xml | xsltproc path/index.xsl | wc -w`
if [ ${words_total} -ge 522 ]
then
	words_total=`expr ${words_total} - 522`
fi
echo $words_total

Afterthought: The whole script could be flawed. I am not familiar with xsltproc and its parameters and don't know if each archive includes a file called "index.xml" or where "path/index.xsl" comes from. Can you try each program in turn to be sure that the flow (particularly to pipelines) is not flawed and that the output of the pipeline is something which can be counted with "wc -w". I'm starting to wonder whether this should be a sequence of commands with no pipeline at all?
