XSL is neat, and it is a functional language, but between XSL and XPath, it is quite verbose. Here's a small section of XSL I use to generate my website (not my blog):

    <xsl:choose>
    
      <!-- ... other code -->
      
      <xsl:when test="name(.) = 'subsection'">
        <xsl:choose>
          <xsl:when test="not(boolean(ancestor-or-self::*/@next)) or ancestor-or-self::*/@next != 'rev'">
            <xsl:if test="boolean(following-sibling::subsection[@listindex != 'no']/attribute::directory)">
              <link rel="next"  href="../{following-sibling::subsection[@listindex != 'no']/attribute::directory}" title="{following-sibling::subsection[@listindex != 'no']/child::title}"/>
            </xsl:if>
            <xsl:if test="boolean(preceding-sibling::subsection[@listindex != 'no'][position()=1]/attribute::directory)">
              <link rel="prev"  href="../{preceding-sibling::subsection[@listindex != 'no'][position()=1]/attribute::directory}" title="{preceding-sibling::subsection[@listindex != 'no'][position()=1]/child::title}"/>
            </xsl:if>
            <link rel="first" href="../{../subsection[@listindex != 'no'][position()=1]/@directory}" title="{../subsection[@listindex != 'no'][position()=1]/title}"/>
            <link rel="last"  href="../{../subsection[@listindex != 'no'][position()=last()]/@directory}" title="{../subsection[@listindex != 'no'][position()=last()]/title}"/>
          </xsl:when>
   
          <xsl:otherwise>
            <xsl:if test="boolean(preceding-sibling::subsection[@listindex != 'no'][position()=1]/attribute::directory)">
              <link rel="next" href="../{preceding-sibling::subsection[@listindex != 'no'][position()=1]/attribute::directory}" title="{preceding-sibling::subsection[@listindex != 'no'][position()=1]/child::title}"/>
            </xsl:if>
            <xsl:if test="boolean(following-sibling::subsection[@listindex != 'no']/attribute::directory)">
              <link rel="prev" href="../{following-sibling::subsection[@listindex != 'no']/attribute::directory}" title="{following-sibling::subsection[@listindex != 'no']/child::title}"/>
            </xsl:if>
            <link rel="first" href="../{../subsection[@listindex != 'no'][position()=last()]/@directory}" title="{../subsection[@listindex != 'no'][position()=last()]/title}"/>
            <link rel="last"  href="../{../subsection[@listindex != 'no'][position()=1]/@directory}" title="{../subsection[@listindex != 'no'][position()=1]/title}"/>
          </xsl:otherwise>
        </xsl:choose>
      </xsl:when>

      <!-- ... other code ... -->
    </xsl:choose>

And yes, there is other code I've omitted for brevity. This is used to generate the navigation links for the site. I initially write this ... prior to 2009 (that's when I moved it into git). There have been some minor fixes to the XSL over the years, but it's largely unchanged (for a reason that I hope is obvious). Yes, I still use it, because it still works, and it's for a static website.
