How to Increment 1 day in Date using XSLT

Question

I have a scenario in which we need to increment 1 day in existing date. Like In =VLOOKUP([@SupplierCode],Suppliers,MATCH("Name",Suppliers[#Headers],0),FALSE) I want to increase 1 day and map its value to SELECT *, EXISTS(SELECT Id FROM TableB WHERE Id= TableA.Id) AS DoesExist FROM TableA . How can I achieve this using XSLT. So, all date constraints should also be handled. like if day is 31 then increment in month.

<subscriptionDate>2015-05-06</subscriptionDate>
