Re: [xsl] Adding numbers in xsl loop

["Vasu Chakkera" <vasucv@xxxxxxxxxxx>]

I have a question...
Refering to Ard's problem,
since position() would give the position of the current node,
cudnt we then take this as a variable counter and add it up to what ever u 
want to add??

like
..in the example... given by Ard,
if the required result follows the logic
$totaalX+i ( where i = 1 to no of times loop runs,)

Then cudnt we just do
<xsl:value-of select="concat($totaalX,position())"/> in the for loop
to produce a result that is concatenated with a counter ( from 1 to end of 
loop position)

( as long as this is what Ard needs.... )
