Can you post an example somewhere of what your Wordpress XML looks like?

Uh, "Facebook"? What's that? Does it have anything to do with this "twitter" thing I've been hearing about lately?

(Sorry, just joking. I'm not in to Facebook, LinkedIn, Twitter, Spotify, del.i.cious, or any of the other "social media" advertiser's honey traps.)

Can you make a small sample file that contains no sensitive material and post a public Dropbox link? Or, if the file is not very large, you can also paste it in-line in this forum. In that case please use the Advanced Editor (finally reinstated, thank you moderators!) to set its syntax highlighting to "XML".

Um, much as I like to help you, I cannot promise anything until I've actually seen the file. It's just that without an example, *no-one* on this forum can.

I could p.m. you an email address, and you could send me your test file, and then I could decide "nah, cannot work with it". That's why I suggested you to make a small (non-sensitive) test file and make it publically available -- so that others can have a go at it as well.

... The Advanced Editor for posts is hiding under the innocuous text "Use advanced editor", at the top right of your edit window. XML syntax highlight is under the button that looks like ">>".

Just for clarity, this is my extremely basic XSLT-that-ought-to-have-worked:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:content="http://purl.org/rss/1.0/modules/content/">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*" />

<!-- Match everything in the root -->
<xsl:template match="/">
          <xsl:apply-templates />
</xsl:template>

<xsl:template name="channel">
          <xsl:apply-templates />
</xsl:template>

<xsl:template name="title">
          <title><xsl:apply-templates /></title>
</xsl:template>

<xsl:template name="item">
          <xsl:apply-templates />
</xsl:template>

<xsl:template name="content:encoded">
          <xsl:apply-templates />
</xsl:template>

</xsl:stylesheet>
