Adding an XSL stylesheet for my RSS and Atom feeds

Jan 13, 2024| 11ty, geek, blogging

Inspired by the styling on Susam's blog feed, I followed this tutorial on using XML stylesheets and added XSL stylesheets for my RSS and Atom feeds. I have RSS and Atom feeds for all my posts as well as for each category or tag (ex: emacs).

To make that happen, I added a line like this to my RSS template:

<?xml-stylesheet href="/assets/rss.xsl" type="text/xsl"?>

and for my Atom template:

<?xml-stylesheet href="/assets/atom.xsl" type="text/xsl"?>

and those refer to:

rss.xsl

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="3.0"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:dc="http://purl.org/dc/elements/1.1/"        xmlns:atom="http://www.w3.org/2005/Atom">
  <xsl:output method="html" version="1.0" encoding="UTF-8" indent="yes"/>
  <xsl:template match="/">
  <html xmlns="http://www.w3.org/1999/xhtml" lang="en">
    <head>
      <title>
        RSS Feed | <xsl:value-of select="/rss/channel/title"/>
      </title>
      <link rel="stylesheet" href="/assets/style.css"/>
    </head>
    <body>
      <h1 style="margin-bottom:0">Recent posts: <xsl:value-of select="/rss/channel/title"/></h1>
