The variable is currently selecting all the word elements that are
children of the current word element and whose value is the same as
the current word element. I don't think that you have word elements
nested inside other word elements, so this will return an empty set
all the time, which is why you're having problems with it.

Try using the following instead:

  <xsl:variable name="entries" select="../word[. = current()]" />

Or of course you could create a key that indexes all the word elements
in the document by their value:

<xsl:key name="words" match="word" use="." />

and then use:

  <xsl:variable name="entries" select="key('words', .)" />

By the way, collecting the words together for this variable is quite
time-consuming, so since you're applying templates to *all* the words,
but only actually processing some of them (within the xsl:if), I'd
move the xsl:variable within the xsl:if (or just before the
xsl:for-each) instead of having it at the top of the template.

12-15. I assume that's what you wanted?

Cheers,
