Grouping records by month

Question

Hi,
I have a group of records in the XML structure as below:
<ListofIO>
<ListOfBipReport1>
<Report>
<FirstName/>
<LastName/>
<Planned>04/12/2011</Planned>
</Report>
<Report>
<FirstName/>
<LastName/>
<Planned>04/10/2011</Planned>
</Report>
<Report>
<FirstName/>
<LastName/>
<Planned>05/08/2011</Planned>
</Report>
</ListOfBipReport1>
</ListofIO>
I would like to group the records by month based on the Planned date.
I used the following code: <?for-each-group:Report;./Planned?><?sort:current-group()/Planned;'ascending';data-type='text'?>
and I formatted the Planned date to display in the format mmm-yy
I would like the report to display info as follows:
Apr-11
First Name
Last Name
First Name
Last Name
May -11
First Name
Last Name
but when I run the report what I see is the following:
Apr-11
First Name
Last Name
Apr-11
First Name
Last Name
May-11
First Name
Last Name
i.e. The grouping is displaying for every record
How do I group the Planned dates for each record together so that I see each month listed only once?
thanks

Your date needs to be in the canonical format to apply any formatting.
You could use the substring function and concat function to extract the month and year and then use that to group by.. not the best way..
