What I was trying to suggest was that you go in two phases:

(a) build a list containing (word, poem number, line number)
(b) group that list by word

and that the output of (a) should be a temporary tree. Sorry if the
reference to position() confused you - I was concentrating on the top-level
design, not the detail.

For example phase 1 might actually be

<xsl:variable name="wordlist">
  <xsl:for-each select="//text()">
    <xsl:for-each select="tokenize(., xxx)">
      <word w=".">
        <poem><xsl:number count="poem"/></poem>
        <line><xsl:number count="l"/></line>
      </word>
    </
  </
</
