<mezo eazon="002X1A">xyz</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....

Here is an XSLT 2.0 stylesheet that produces above output:


<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  version="2.0">

<xsl:output indent="yes"/>

<xsl:template match="/">
<instance>
<xsl:for-each-group select="//C_TAX_REPORTING_NAME" group-by="(position() - 1) idiv 2">
<mezo eazon="{format-number(current-grouping-key() + 1, '000')}X1A">
<xsl:value-of select="current-group()[1]"/>
</mezo>
<mezo eazon="{format-number(current-grouping-key() + 1, '000')}X2A">
<xsl:value-of select="current-group()[2]"/>
</mezo>
</xsl:for-each-group>
</instance>
</xsl:template>


</xsl:stylesheet>
