XML table for LaTeX

Question

Suppose I have an XML form table

<table> <tr> <td>First Name:</td> <td>Bill Gates</td> </tr> <tr> <td rowspan="2">Telephone:</td> <td>555 77 854</td> </tr> <tr> <td>555 77 855</td> </tr> </table> 

which I want to convert to LaTeX using XSLT (I stole this example elsewhere). As a result i want

 \documentclass{memoir} \usepackage{multirow} \begin{document} \begin{tabular}{*{10}{c}} First name & Bill Gates &\\ \multirow{2}{*}{Telephone:} & 555 77 854 &\\ & 555 77 855 & \end{tabular} \end{document} 

For the most part, there is a fair one-to-one correspondence between the two table formats. So this works pretty well for the most part:

 <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="text" omit-xml-declaration="yes" encoding="UTF-8"/> <xsl:template match="/"> \documentclass{memoir} \usepackage{multirow} \begin{document} <xsl:apply-templates/> \end{document} </xsl:template> <xsl:template match="table"> \begin{tabular}{*{10}{c}} <xsl:apply-templates/> \end{tabular} </xsl:template> <xsl:template match="tr"> <xsl:apply-templates />\\ </xsl:template> <xsl:template match="td[not(@rowspan) and not(@colspan)]"> <xsl:apply-templates/> &amp; </xsl:template> <xsl:template match="td[not(@colspoan)]"> \multirow{<xsl:value-of select="@colspan"/>}{*}{<xsl:apply-templates/>} &amp; </xsl:template> <xsl:template match="td[not(@rowspan)]"> \multicolumn{<xsl:value-of select="@colspan"/>}{l}{<xsl:apply-templates/>} &amp; </xsl:template> <xsl:template match="td"> \multirow{<xsl:value-of select="@rowspan"/>}{*}{\multicolumn{<xsl:value-of select="@colspan"/>}}{l}{<xsl:apply-templates/>} &amp; </xsl:template> </xsl:stylesheet> 

The problem is & (which become & exit). In LaTeX, you will need one at the beginning of the third line, where the extended cell is located. This does not apply to the XML table. How can I get around this problem?
