Theres a library of date-handling functions and templates available at
www.exslt.org. Many of these are implemented in pure XSLT so they can be
used with any XSLT 1.0 processor.

> Hi Guys...need your help in below explained XML to CSV transformation.

> Input:
> -------
> <Result>
>    <Timesheet>
>     <ID>888001</ID>
>     <Name>Abhi</Name>
>     <Week_Ending_Date>9/1/09</Week_Ending_Date>
>     <Dept>Test Department</Dept>
>     <Hours_Basic_Saturday>5:00</Hours_Basic_Saturday>
>     <Hours_Basic_Sunday>0:00</Hours_Basic_Sunday>
>     <Hours_Basic_Monday>9:00</Hours_Basic_Monday>
>     </Timesheet>
> </Result>   
>            
> Desired Output:
> -----------------
> The CSV file should have multiple records depending on days worked and
> --> Word date as a date value derived from 'Week_End_Date'
> which is always a friday date. i.e if Week_End_Date is
> 02/10/2009, Work date for Monday should be derived by
> something like date(Week_End_Date) - 4.

> Any idea how can i implement such date functions in XSLT 1.0

> ID,     Name, Week Ending, Dept,    Work Date, Reg Hours
> 888001, Abhi, 2/10/09, Test Department,26/09/09 , 5:00
> 888001, Abhi, 2/10/09, Test Department,28/09/09 , 9:00
