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

This could be easily done using the following expression:

days-from-duration(xs:date('yyyy-MM-dd')-xs:date('yyyy-MM-dd'))

For example:

days-from-duration(xs:date('2012-06-30')-xs:date('2012-06-18')) 

will give result of 12
