Re: Variables and Strings

[Norman Walsh <ndw@xxxxxxxxxx>]

/ skvenkat@xxxxxxx was heard to say:
|      But what I meant was can I equate a string to a variable like (def x
| x-string) where x-string is "2". Anyway, more precisely my problem was
| in relation to geting the number of columns in a grid (matrix), with say
| <array><r><c>1<c>0<c>0<r><c>0<c>1<c>0<r><c>0<c>0<c>1</array> where <r>-row,
| <c>-column. I use (element array make grid) (element c make grid-cell), but
| there is no grid-row flow object, so I have to supply the number of columns in
| the make grid charchterstic by counting the number of <c> tags. How do I do
| that?

Um, ... off the top of my head:

(element array
  (let ((num-cols (node-list-length
                    (select-elements (children (current-node)) "c"))))
  ...))

                                        Be seeing you,
                                          norm
