Instead of a for-each loop, you can write a recursive named template to 
achieve this..

<?xml version="1.0"?> 
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
version="1.0">

<xsl:output method="text" />

<xsl:variable name="alphabets" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'" />

<xsl:template match="/">
  <xsl:call-template name="IterateAlphabets">
    <xsl:with-param name="alphabets" select="$alphabets" />
  </xsl:call-template>
</xsl:template>

<xsl:template name="IterateAlphabets">
  <xsl:param name="alphabets" />
  
  <xsl:if test="string-length($alphabets) != 0">
    <xsl:value-of select="substring($alphabets,1,1)" /><xsl:text>
</xsl:text>
    <xsl:call-template name="IterateAlphabets">
      <xsl:with-param name="alphabets" select="substring($alphabets,2)" />
    </xsl:call-template>
  </xsl:if>
</xsl:template>

</xsl:stylesheet>
