Adding conditions to current-group()

Question

First of all I want to thank all the experts out there who read these boards and help folks like myself figure it out. I'm new to this and sort of testing the waters for my clients (our first report was implemented last week!), so there are no local experts. Your help is greatly appreciated.
Now to my new question. For my second report I'm trying to create something a little more dynamic. I'm moving all of my totalling and grouping from the data definition to the template. I have a large set of records all returned by a single query. The records have a field called 'Report'. The field contains either a 1 or a 2 depending on where in the template the records should be displayed.
This is a few lines from my template to give you an idea of what I'm dealing with...the tabs don't show but hopefully I've labelled it well enough that you can see what I'm trying to achieve.
<?for-each-group:G_REPORT;./PAGEBREAK_SEG?>
<?for-each-group:current-group();./SECOND_SEG?>
<?for-each-group:current-group();./THIRD_SEG?>
**new condition***
     <?for-each-group:current-group();./CAT3?>
     <?for-each-group:current-group();./ACCOUNT_SEG?>
     <?ACCOUNT_SEG?>
     <?ACCOUNT_DESC?>
     <?APRIL?>
          <?end for-each?>--END ACCOUNT_SEG
     <?CAT3_DESC?>
     <?sum (APRIL)?>
     <?end for-each?>
**end of new condition***
--records where report=2 will be displayed here
<?split-by-page-break:?><?end for-each?> --ENDS THIRD_SEG
<?split-by-page-break:?><?end for-each?>--ENDS SECOND_SEG
<?split-by-page-break:?><?end for-each?> --ENDS PAGEBREAK_SEG
What I'd like to do is add another condition based on the value of 'Report'. If the report field is '1' I want to go ahead and group the records as indicated above. If the report field is '2' I want to skip over the records. Those records will be displayed later in the template.
Any help would be appreciated.
Thank you.

Hi
The best approach will be to use an XPATH expression. there is a primer on the XPATH standard in the BIP docs, check it out.
At its most simple its a way to introduce an if statement into your template e.g. loop over these rows of data if the document type is INVOICE, this would be <?for-each:ROW[DOC_TYPE='INVOICE']
You will be able to use the same command structure for your data. There was not a Report field (element) in your example below but you can use
<?for-each:current-group()[Report='1']?>
this will only show the rows where Report = 1, conversely
<?for-each:current-group()[Report !='1']?>
shows every row where Report does not equal 1.
Give it a try, if you get stuck, some XML data and the structure of the template will help to help you
