title: calculate age in xslt from birthday
body: <p>I have a variable caled <code>Birthday</code> which will have value like <code>1/1/1970</code>. I need to calculate the age of a person based on that value. It would basically be the year from <code>currentdate()-year</code> from the <code>Birthday</code> variable. But How do I achieve this in XSLT? It is related to sharepoint DateView webpart. There is a field <code>Birthday</code> of <code>datetime</code> type. I need to extract age using that field. Can anyone point me in the right direction?</p>
