Section 45.4 String Parameters
To pass string parameters to
xsltproc, use a command like the following (possibly with
xsltproc -o animals.tex --stringparam latex.font.size "20pt" /path/to/xsl/pretext-latex.xsl ~/books/aota/animals.xml
You can use as many
stringparam as you like on the command-line (or in your scripts). The quotation marks are not strictly needed in this example, but if the value of the parameter has spaces, slashes, etc., then you need to quote-protect the string from the command-line processor, and either single or double quotes will work (and protect the other kind).
