Re: [xsl] $variables with xsl:key()

[Wendell Piez <wapiez@xxxxxxxxxxxxxxxx>]

Steve,

I'm sorry we all seem to be having such a hard time with this.

The reason, to me, appears to be that your presentation of your 
problem is falling into a gap between two useful approaches:

1. Asking a general question, considering the responses, and if 
necessary reframing the question and pursuing open-ended dialogue. 
(Not "moving the goalposts" or expressing unhappiness with anyone's responses.)

2. Presenting a complete encapsulated problem, including source, 
attempted stylesheet, and stated requirements probably including the 
form of desired output. "Complete and encapsulated" means the problem 
is trimmed down, ideally to a single screen, so an expert can survey 
it and pull out the problem quickly. If it requires any guessing at 
all, we are not likely to do anything with it since who wants to 
offer an answer and then be wrong?

In your post below, I can see several possible difficulties, but I 
can't be sure which is the culprit since the entire problem isn't 
presented explicitly.

For one thing, you tell us your problem is with the key, but without 
key declarations we have no way of knowing with any certainty how 
your keys work or are supposed to. Also, the sample data you provide 
doesn't match up: there's no complete problem here.

To make things a bit worse -- I'm about to get scarce for a few hours 
or days, so I'm relying on others on the list to step in and help (as 
we all must do sometimes). Accordingly, when you do your homework and 
present a problem succinctly and completely you do us all a favor, 
since you enable such handoffs. (In great part the list is driven by 
a friendly competition to come up with good answers.) And just so, 
since we rely on each other, disrespect (or even the unintended 
appearance of it) towards any contributor amounts to disrespect to 
all of us, and lessens the chances of a questioner's getting prompt 
help in future. I don't say this to be punitive, but rather to draw 
attention to one potential difficulty that can fairly easily be 
avoided or dealt with.

Regards,
Wendell
