Yes, but not if you think about it procedurally the way you are doing. You
need to think how the output value can be computed as a function of the
input. Try something like:

<xsl:for-each select="G_REP_TRX_DETAIL_INFO/C_TAX_REPORTING_NAME">
  <mezo eazon="{format-number((position()+1) idiv 2,
'000')}X{((position()+1) mod 2) + 1}A">
    <xsl:value-of select="."/>
  </mezo>
</xsl:for-each>
