XML don't keep '&', '<', '>' as '&', '<', '>' because, this is special symbols, using in tags, so XML keep they as '&amp', '&lt', '&gt'. And as i see, QDomText don't decode them to origin form (maybe bug), when is convertes to `QString`, so we need do it by hands.
  
  
  Ok, I think this is not related to xls. I created now a maxima worksheet and did a simple matrix([1,2],[3,4]). The result xml content is
  
    <!DOCTYPE CantorWorksheet>
    <Worksheet backend="Maxima">
     <Expression>
      <Command>matrix([1,2],[3,4])</Command>
      <Result type="latex" filename="cantor_tex-SiCiCb.eps">\begin{eqnarray*}
    \begin{pmatrix}1&2\\ 3&4\\ \end{pmatrix}
    \end{eqnarray*}</Result>
     </Expression>
     <Expression>
      <Command></Command>
     </Expression>
    </Worksheet>
  
  Out of this Cantor generates without your fix
  
    \documentclass[a4paper,10pt,fleqn]{article}
    
    \usepackage{fullpage}
    \usepackage{graphicx}
    \usepackage[utf8]{inputenc}
    \usepackage{amsmath,amssymb}
    
    \begin{document}
    \begin{verbatim}
    matrix([1,2],[3,4])
    \end{verbatim}
    \begin{eqnarray*} \begin{pmatrix}1&2\\ 3&4\\ \end{pmatrix} \end{eqnarray*}
    \begin{verbatim}
    
    \end{verbatim}
    \end{document}
  
  Do you see where those &amp's in the XML-content come from? They are not part of maxima output.
