Subject: Re: [xsl] Anyone can explain me this syntax? From: "G. Ken Holman" <gkholman@xxxxxxxxxxxxxxxxxxxx> Date: Tue, 13 Jan 2004 10:49:11 -0500 |
>From Muenchian method of grouping, I always use something like this:
ROW[count(. | key('relacion_x_cobertura', REL_ID)[1]) = 1] ... - Why the . (dot) is used?
why if I omit it, it doesn't work (it returns all elements)?
- What's the meaning of the | (pipe)?
- What's the meaning of [1]?
I have always used things like [FIELD_NAME=some_value]. I understand that perfectly, but what about placing only that number in the brackets? I tried by using [2] and it worked too... or, perhaps I was lucky?
