xslt - subtracting days

Question

Is it possible with xslt to take a date field and subtract N number of days from it? If so, can you please provide me an example?

Answer 1

Here is a demonstration how to do this in XSLT 2.0:

 

 
  

  Today is: 
  30 days ago it was: 
  365 days ago it was: 
 

when this transformation is applied on any XML document (not used), the wanted, correct result is produced:

  Today is: 2010-10-07-07:00
  30 days ago it was: 2010-09-07-07:00
  365 days ago it was: 2009-10-07-07:00
