This for-each-group

 <xsl:for-each-group
   select="//*/string-join(ancestor-or-self::*/name(), '/')"
   group-by=".">
	<xsl:sequence select="concat('&#xa;', ., ' - ', count(current-group()))"/>
 </xsl:for-each-group>

give this result:

a - 1
a/b - 2
a/b/x - 3
a/b/x/w - 3
a/b/y - 1
a/c - 1
a/c/w - 2
