Subject: Re: [xsl] XPath MOD 10 calculation From: "Jesper Tverskov" <jesper@xxxxxxxxxxx> Date: Fri, 25 May 2007 11:19:11 +0200 |
Running that gave me 7 - when the check digit should be 3 shouldn't it? You don't appear to be doing the mod 10 calculations correctly (according to the steps on wikipedia) - you do the summing, mod 10 it, take that from 10 and then mod 10 it again.
I hope we are testing different things then. When I copy my code out of my email and into two new files it works well. Also with your <upc>036000291452</upc> example.
My code tests if a UPC is correct based on the checksum, if it is, nothing is returned, if it is not, "UPC is not legal" is returned.
