XML : Compare julian date in XSLT

I have a requirement where I have to find out the most recent datetime in julian from list of dates by using XSLT.

If I pass the below XML

Input:

  <Orders>  <Order>  <OrderNumber>100</OrderNumber>  <Date>116256</Date>  </Order>  <Order>  <OrderNumber>101</OrderNumber>  <Date>116256</Date>  </Order>  <Order>  <OrderNumber>102</OrderNumber>  <Date>116276</Date>  </Order>  </Orders>    

Output:

  <Result>  <Date>116256</Date>  </Result>    

Please help me with the XSLT.

Thanks Yatan
