Finding the difference between 2 dates in xslt

Question

Is there a less then kludgey way of finding the difference in days between 2 dates in xslt? If so can you point me in the right direction. I am receiving dates in the format

Answer 1

Use XSLT 2.0 (XPath 2.0) for this:

when this transformation is applied on the following XML document:

 04/06/2011
 01/11/2010

the wanted, correct result (the difference is 450 days) is produced:

450
