Creating mailing labels - 3 columns in a row.

Hi,

I have an xmls in the following form

<ADDRESSES count="5">
 <ADDRESS>
  <STREET>421 VULCAN</STREET>
  <CITY>BUFFALO</CITY>
  <STATE>NY</STATE>
  <ZIP>14207</ZIP>
</ADDRESS>
...
...
</ADDRESSES>

I want to transform this to a table with 3 columns in a row.
(information from each <ADDRESS> node goes to one cell). how can 
I achieve this?

Here is my xsl which generates a table with only one column.

        <table border="0" width="804" cellspacing="0">
                <xsl:for-each select="ADDRESS" >
                        <tr>
                                <td height="96" width="267" class="MLFont">
                                        <xsl:value-of select="STREET" />
                                        <br/>
                                        <xsl:value-of select="CITY" />
                                        <xsl:text 
disable-output-escaping="yes">, </xsl:text>
                                        <xsl:value-of select="STATE" />
                                        <xsl:text 
disable-output-escaping="yes"> </xsl:text>
                                        <xsl:value-of select="ZIP" />           
                        
                                </td>
                        </tr>
                </xsl:for-each>                 
        </table>

My Question: Is it possible to generate a <tr> and </tr> element only 
if, it is a third element.


Thanks in advance.
