Hi Mathieu,
use <xsl:sort select=... data-type="number"/>.
The default data-type is text:
1 < 2 < 3 < 6 results in 172 < ... < 68
Regards,
Markus

Betreff: [xsl] Unexpected sort order on a multi sort
Hi,
I am sure I am missing an obvious one here, but I am getting unexpected output,
based on the sort order. I stripped my XML down to the bare minimum here for
an example.
Output
SUBJECTS, Exp Var.Pos 172, Exp Var.Pos 202, Exp Var.Pos 236, Exp Var.Pos 316,
Exp Var.Pos 68
PA126746586, C/G, C/C, G/A, T/T, G/G
Expected the last variant to be the first based on sorting, since <position>
element is a number, shouldn't it be 68, 172, 202, 236, 316?
Do I have a strange typo? I added the number() function as a last stab, but I
was getting the same results without it? What did I miss!
