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

I can see that all the mentioned solutions are for XSLT 2.0. I have similar solution for XSLT 1.0 using EXSLT date:add

Example: Consider that the number of days to be subtracted is 365 and we need it as the default start date. In this case, we have to provide the duration 365 days in xs:dayTimeDuration format i.e. '-P365D'.

Please find below the code.
