the structure of the xslt for text is (or can be) very different.
Consider just one step of your problem adding a blank line between
letters (assuming sorting is done.


If you are just generating text, you don't need to group anything, you
just need to put out a blank line every now and then

<xsl:for-each seelct="*">
<xsl:value-of select="."/>
<xsl:if tests="not(substring(.,1,1)=substring(following-sibling::*[1],1,1))">&#10;</xsl:if>
</xsl:for-each>

If however you need to produce markup, say putting all the rows that
start with the same letter in a div then you need to group all the
elements that start with the same letter together
so in xslt 2

<xsl:for-each-group group-by="substring(.,1,1)">
<div>
<xsl:copy-of select="current-group()"/>
</div>
</xsl:for-each-group>

or, as we used to write it in xslt 1,

<xsl:key name="l1" match="*" use="substring(.,1,1)"/>

<xsl:for-each
select="*[generate-id()=generate-id(key('l1',substring(.,1,1)))]">
<div>
<xsl:copy-of select="key('l1',substring(.,1,1))"/>
</div>
</xsl:for-each>
