Re: sorting the result of a calculation on xml that ca

Hi Sean,

Wellcome to the list.

> CALC div: <xsl:value-of select="(HomePupils + GuestPupils div Teachers) "/>

I would guess that this gives a NaN when HomePupils is empty.
That goes for your sorting algorithm as well.

<xsl:value-of select="(concat(HomePupils, substring('0', 1,
number(normalize-space(HomePupils)=''))) + GuestPupils div
Teachers)"/>

It would be better if you could change the input document to provide 0
instead of an empty string.

Hope this helps.
