Min XML ser egentligen ut så här (bara det viktigaste):

...
        <table:table-row>
          <table:table-cell>
            <text:p>foreach ($receipts as $receipt) {</text:p>
          </table:table-cell>
          <table:table-cell>
            <text:p>$receipt-&gt;id</text:p>
          </table:table-cell>
          <table:table-cell>
            <text:p>$receipt-&gt;name</text:p>
          </table:table-cell>
          <table:table-cell>
            <text:p>$receipt-&gt;amount</text:p>
          </table:table-cell>
          <table:table-cell>
            <text:p>$receipt-&gt;vat1</text:p>
          </table:table-cell>
          <table:table-cell>
            <text:p>$receipt-&gt;vat2</text:p>
          </table:table-cell>
          <table:table-cell>
            <text:p>$receipt-&gt;vat3</text:p>
          </table:table-cell>
          <table:table-cell>
            <text:p>$receipt-&gt;net</text:p>
          </table:table-cell>
          <table:table-cell>
            <text:p>$receipt-&gt;date</text:p>
          </table:table-cell>
          <table:table-cell/>
        </table:table-row>
...mer XML...

Notera foreach som står i första cellen, den matchas i en preg_match, och sedan klonas raden lika många gånger som det finns värden i arrayen.
Jag tror att problemet ligger i foreach ($node->childNodes) eftersom den tar en ögonblicksbild av barnen och loopar dem, och tar inte hänsyn till ändringar.

Hur kan man tänka på annat sätt?
