"(" ")" in xml file causing errors

Hi,

I have an xml file which contains data like
	<result><row>
								<(expression)>3DO COMPANY</(expression)><(expression)>THDOQ</
(expression)><(expression)>95688</(expression)><(expression)>GVRC2   </
(expression)><(expression)>0.01300 / 0.04000(5000 x 5000)</
(expression)><(expression)> </(expression)><(expression)>02-11</(expression)>								
	</row>	</result>

I am trying to use this xml to convert it to excel format(I have an xsl file 
that converts xml to xls format).
When used directly it is giving an error "The content of elements must consist 
of well-formed character data or markup." . I thought it could not because of 
the "(". Do you think so?. 

I want to get rid of braces( "(" and ")" from this xml and have another xml 
with the same data without braces. I am trying to write xsl to do the same 
but it is not working. Can someone please help.

My xsl file
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet
  version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  >


<xsl:template name="replace-string">
    <xsl:param name="text"/>
    <xsl:param name="replace"/>
    <xsl:param name="with"/>
    <xsl:choose>
      <xsl:when test="contains($text,$replace)">
        <xsl:value-of select="substring-before($text,$replace)"/>
        <xsl:value-of select="$with"/>
        <xsl:call-template name="replace-string">
          <xsl:with-param name="text"
select="substring-after($text,$replace)"/>
          <xsl:with-param name="replace" select="$replace"/>
          <xsl:with-param name="with" select="$with"/>
        </xsl:call-template>
      </xsl:when>
      <xsl:otherwise>
        <xsl:value-of select="$text"/>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:template>




  <xsl:template match="result">	
  	<xsl:variable name="leftBraceReplaced">
      <xsl:call-template name="replace-string"> <!-- imported template -->
        <xsl:with-param name="text" select="." />

        <xsl:with-param name="replace" select="')'"/>
        <xsl:with-param name="with" select="'))'"/>
      </xsl:call-template>
    </xsl:variable>
    <xsl:for-each select="row">

		   </xsl:for-each>                             
    </xsl:for-each>

  </xsl:template>

    
   <xsl:template match="@*|*|text()|processing-instruction()">
    <!-- Catch all template. Just pass along unmodified everything we
         don't handle. -->
    <xsl:copy>
      <xsl:apply-templates select="@*|*|text()|processing-instruction()"/>
    </xsl:copy>
  </xsl:template>

</xsl:stylesheet>
