I guessed this was easy, so I tried but initially failed. I searched for an answer and was surprised when I couldn’t find a good one. An hour later I worked out a solution based on parent::node() that seems stable on all XML files. I post it here for future reference:

<xsl:for-each select="//*"><!--loop all levels of nodes-->
   <xsl:if test="position() > 2"><br/></xsl:if><!--line break after last-->

   <xsl:choose>
      <xsl:when test="*"><!--does this node have children-->
         <xsl:if test="position() > 1">
            <!--print node + ancestor relationship-->
            <xsl:value-of select="concat(name(parent::node()),'->',name())"/>
         </xsl:if>
      </xsl:when>

      <xsl:when test=".=text()"><!--does this node have PCDATA-->
