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.
