Re: [xsl] Problem using Key on multiple elements

[Sreenath Juluri <jssreenath@xxxxxxxxx>]

hi Joris Gillis!

Thnx. It works. but i didnot understand the funda....

What i understand is this. generate-id() will create a unique id based
on the current value of the context node. U suggested doing this

<xsl:for-each select="a:xtvd/a:productionCrew/a:crew/a:member
        [generate-id()=generate-id(key('roleNames',
                concat(a:givenname,'+',a:surname))[1])]
        /a:givenname">

In my source xml a:member has 3 elements role, givenname and surname.
In the abv for-each we are generating an id for a:member(with 3
elements) and comparing the same with the id for 
concat(a:givenname,'+',a:surname) in the key roleNames.
I did not understand how both the ids match? can u plz explain me
this...hopefully this shud explain where i went wrong in my original
approach.

Thnx
Sreenath.
