XSLT issue

Hi

Could someone explain me how this xslt works in biztalk? if i want to
change 
the node path to full path, how to do it? 

<xsl:variable name="unique-countries" 

select="//cities/city[not(@[EMAIL PROTECTED]
)]/@[EMAIL PROTECTED]
"
/>

<countries>

          <xsl:for-each select="$unique-countries">

                  <country name="{.}">

                          <xsl:for-each
select="//city[@[EMAIL PROTECTED]
()]">

                                <city><xsl:value-of select="@[EMAIL PROTECTED]
"
/></city>

                        </xsl:for-each>

                </country>

        </xsl:for-each>

  </countries>



I am working on grouping nodes using XSLT in biztalk. I used the above
XSLT 
( i got it from online) and I got output without child nodes, ****ry.  

It looks like It didn't enter into for loop. I think I need to give node 
full path. 

Could someone tell me which places i need to change? I tried, no luck so
far.



Thank you in advance,

Siva
