James AgnewSubject: xslt 2.0 calendar
Author: James Agnew

Hi

I'd like to be able to generate a simple calendar using xslt 2.0.

Is there a way to know:

1. How many days are in a given month
2. How to add a duration to a given date (e.g. add a day to '2006-03-31' to produce '2006-04-01')

There appears to be lots of new date formatting, extraction and duration functions in the xslt 2.0 spec but I can't find any that achieve the above. I'm using SS 2006 Enterprise R2 with Saxon 8.7.

Any help much appreciated.

Thanks, James

>1. How many days are in a given month

You could use a sequence of 12 items and index that on the required month... handling exceptions for leap years...

Or you can rely on XPath date functions, struggling a bit:

declare function local:getDaysInMonth($date as xs:date) as xs:integer
{
let $nextMonth := month-from-date($date)+1
return
if($nextMonth = 13) then 31
else
day-from-date(xs:date( concat(year-from-date($date),'-',if ($nextMonth>9) then $nextMonth else concat('0',$nextMonth),'-','01')) - xdt:dayTimeDuration('P1D'))
};

...then you can call:
local:getDaysInMonth('2006-04-01')


>2. How to add a duration to a given date (e.g. add a day to '2006-03-31' to produce '2006-04-01')

xs:date('2006-04-30')+xdt:dayTimeDuration('P1D')

...btw, I used XQuery to write the function above... being that mostly XPath 2.0, you can just use most of the same code in XSLT 2.0.
