BI Publisher - How to separate values by comma

Question

I have this row that I'll be showing as comma separated:

Name1 number1, Name2 number2, Name3 number3, Name4 number4

I put this in a for-each loop like:

<?for-each-group@inlines:current-group():./NAME?>

In the RTF, it is shown as:

for-each <?NAME?> <?NUMBER?> , end

So I put a comma in the loop, but there is always an extra comma in the end, how do I remove that?

Name1 number1, Name2 number2, Name3 number3, Name4 number4,

Answer 1

<?for-each-group@inlines:current-group():./NAME?>
<?NAME?> <?NUMBER?><?if@inlines:position()!=last()?>, <?end if?>
<?end for-each-group?>

position() function

last() function
