Re: for-loop in xslt problem

Frankie,

This is a common problem for those of us who have just picked up XML and
learned that writing XML is quite different than most other common
languages.  To tackle this problem, you need to look at the for loop in a
slightly different manner.  XML does not have a mechanism for updating
"variables" without using recursion.  So, if I take a little liberty and
modify your for loop, you might see some psuedo-code like this:

variable  max = value-of total;
variable  skip = value-of skip;
call forLoop                            //  this starts the recursion
    with param total = max;
    with param skip = skip;


function forLoop (count, total, skip) {
     param name count = 0;
     param name total = $max;
     param name skip = $skip;

         //  if we haven't made it to the total yet, then repeat the call
         if  test = $count lessThan total {
                print "Print This!";
                call forLoop
                    with param count = count + skip;
                    with param total = total;
                    with param skip = skip;
         }
}

Hope that makes sense!
bix
