[xsl] Re: How to multiply 2 sequences ?

["TEICHERT, Peter" <Peter.TEICHERT@xxxxxxxxxx>]

Hello,

referring to Michael Kays math formula representation I provide more details
what I am searching for.

food item 1: X1 = { x1_1,x1_2,...,x1_n }, where x1_n are food ingredients in
mg/ 100 g ; X are extracted as nodes from xml db
food item 2: X2 = { x2_2,x2_2,...,x2_n }, where x2_n are food ingredients in
mg/ 100 g
...

every food ingredient of one single food item should be multiplied with his
own weight factor Y

food item X1  -  weight factor Y1
food item X2  -  weight factor Y2

Therefore the math formula may be described as followes :

Y1 * X1 = Y1 * x1_1, Y1 * x1_2,..., Y1 * x1_n }
Y2 * X2 = Y2 * x2_1, Y2 * x2_2,..., Y2 * x2_n }

After multiplication with the weight factor the summation over the single food
ingredients
should be done as followes :

          Y1 * x1_1 + Y2 * x2_1 + ...+Yn * xn_n

Thanks for quick answer.

best regards

Peter Teichert
