Rails - Sep 2008 - Record Count in AR using to_xml Options

Hi,
    I''m new to Ruby & using ROR as a web service. I''m
returning XML
using statement:

@persons = Person.find(:all)
render :xml => persons.to_xml()


Now, this returns xml fine without any issues. However, it does not
return the number of records. Lets say there are 2 records returned
by
the query as shown below:


<?xml version="1.0" encoding="UTF-8"?>
<persons>
     <person>
          <fname>Vick</fname>
     </person>
     <person>
          <fname>John</fname>
     </person>
</persons>


Now, I need output xml as shown below which will include count as
well:
<?xml version="1.0" encoding="UTF-8"?>
<persons>
     <totalcount>2</totalcount>
     <person>
          <fname>Vick</fname>
     </person>
     <person>
          <fname>John</fname>
     </person>
</persons>


Can anyone help me out???


Thanks in Advance!
