Subject: RE: [xsl] Using keys when unique identifier is a multi node value From: "M. David Peterson" <m.david@xxxxxxxxxx> Date: Sat, 27 Mar 2004 09:08:25 -0700 |
Yeah, you will have to fix it but if you architect it correctly and allow for the fact that you will be "indexing" on a unique identifier at a later date then it wont be any where near the headache that it could be if you don't. Ive got a solution that I think will help you achieve your goal at hand while allowing for a simple fix in the future... but I just finished an early morning 2 hour solutioning/documenting that solution session at which the 1 hour mark my body was making low rumbling growns... within 15 minutes they became idle threats, and just recently a war was declared... ive got it in a stand off at the moment but I shouldn't press my luck.. give me 30 minutes before I am able to get back to my computer...

I actually spoke with the developer who is providing me with the XML on this. That is something that will be accounted for on the next iteration of our xml serialization. Unfortunately, that also means I will have to go back and fix the xsl. -----Original Message----- From: Robert Koberg [mailto:rob@xxxxxxxxxx] Sent: Saturday, March 27, 2004 10:35 AM To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx Subject: Re: [xsl] Using keys when unique identifier is a multi node value Kenny Akridge wrote: > I've looked at the FAQ and can't seem to find an exact answer.

I don't think you want to use first and last name as unique identifiers. The chance of having two Bill Smiths is pretty high... Why not just create a truly unique identifier and use that as your key/@use? <Attendance id="a12345"> > <FirstName>Bill</FirstName> > <LastName>Smith</LastName> > ... some other important data > </Attendance> best, -Rob > > Thanks
