Subject: Re: [xsl] sorting the result of a calculation on xml that can have missing/blank tags From: Ragulf Pickaxe <ragulf.pickaxe@xxxxxxxxx> Date: Wed, 14 Dec 2005 12:25:52 +0100 |
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. Ragulf Pickaxe :-)
