Parsing the stylesheet takes a single function call, which takes a
variable of type xmlChar:
cur = xsltParseStylesheetFile((const xmlChar *)argv[i]);
In this case, I cast the stylesheet file name, passed in as a
command line argument, to xmlChar. The return value
is of type xsltStylesheetPtr, a struct in memory
that contains the stylesheet tree and other information about the
stylesheet. It can be manipulated directly, but for this example you
will not need to.
