Portion of poetry text not shown in html page created by xslt

i'm working on the digitalization of a text, but a portion of poetry in the middle of the text is not shown, can you help me?

XSL code: http://ift.tt/1t79LhE XML code: http://ift.tt/1ySuepD

The portion of the XML file that is not transformated is:

<div type="poetry">
    <epigraph>
        <lg rhyme="ababcb">
            <l><name type="person">Beatrice</name> tutta ne l’etterne <rhyme label="a">rote</rhyme></l>
            <l>fissa con li occhi stava; e io in <rhyme label="b">lei</rhyme></l>
            <l>le luci fissi, di là sù <rhyme label="a">rimote</rhyme>.</l>
            <l>Nel suo aspetto tal dentro mi <rhyme label="b">fei</rhyme>,</l>
            <l>qual si fé <name type="person">Glauco</name> nel gustar de l’<rhyme label="c">erba</rhyme></l>
            <l>che ’l fé consorto in mar de li altri <rhyme label="b">dèi</rhyme>.</l>
        </lg>
    </epigraph>
</div>
