[xsl] conditional increment under XSL for-each loop

["anil an.kumar" <anil.an.kumar@xxxxxxxxxx>]

Hi Team,

I have a requirment which should show the xml o/p like below

<instance>
<mezo eazon="001X1A">abc</mezo>
<mezo eazon="001X2A">def</mezo>
<mezo eazon="002X1A">xyz</mezo>
<mezo eazon="002X2A">abc</mezo>
<mezo eazon="003X1A">def</mezo>
<mezo eazon="003X2A">xyz</mezo>
<mezo eazon="004X1A">aaa</mezo>
<mezo eazon="004X2A">bbb</mezo>
<mezo eazon="005X1A">ccc</mezo>
<mezo eazon="005X2A">xyz</mezo>
</instance>


The tag "001X1A"  should frame in such a way that,
POINT1 : The number appearing before 'A' should reset after every two 
records
POINT2 : The number appearing before 'X' should be same and need to 
increment by 1 for every two records.
like 001,001 then 002,002 then 003....


Is this possible to get through the XSL

KIindly advice
