Re:  XSL/XPath to generate a list of ancestors?
I think this could be simple to solve with XSLT 2.0. Below is the
working stylesheet:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

<xsl:output method="xml" indent="yes" />

<xsl:template match="/">
    <xsl:apply-templates select="//*[@name][not(@name = 'root')]" />

<xsl:template match="*">
    <xsl:value-of select="string-join(ancestor-or-self::*[not(@name =
'root')]/@name,'.')" />


This when applied to the given XML, produces output:

<?xml version="1.0" encoding="UTF-8"?>
