Alternate table row color via XSL when generating pdf

I am very new to XSLT. I want to implement alternate colors in my table rows. Even rows - # EDF2F8 and Odd rows - # A7BFDE should be displayed.

I have an xsl that looks like this:

<xsl:apply-templates select="records"/>

<xsl:template match="records">
  <fo:table-row>
    <fo:table-cell>
            <xsl:value-of select="Firstname"/>
    </fo:table-cell>
    <fo:table-cell>
            <xsl:value-of select="lastname"/>
    </fo:table-cell>
    <fo:table-cell>
            <xsl:value-of select="Phone number"/>
    </fo:table-cell>
  </fo:table-row>

      

        
        
        
      

    

I tried using the below code but it didn't work:

<xsl:variable name="css-class">
<xsl:choose>
<xsl:when test="position() mod 2 = 0">
<xsl:attribute name="bgcolor">#EDF2F8</xsl:attribute>
</xsl:when>
<xsl:otherwise>
<xsl:attribute name="bgcolor">#A7BFDE</xsl:attribute>
</xsl:otherwise>
</xsl:choose>
</xsl:variable>

<fo:table-row class="{$css-class}">
   <fo:table-cell>
            <xsl:value-of select="Firstname"/>
    </fo:table-cell>
    <fo:table-cell>
            <xsl:value-of select="lastname"/>
    </fo:table-cell>
    <fo:table-cell>
            <xsl:value-of select="Phone number"/>
    </fo:table-cell>
  </fo:table-row>

      

        
        
        
      

    

I really appreciate any help on this.

Part of my code that I edited and it doesn't work either:

<xsl:template match="records">
<xsl:variable name="bgclr">
<xsl:choose>
<xsl:when test="position() mod 2 = 0">#A7BFDE</xsl:when>
<xsl:otherwise>#EDF2F8</xsl:otherwise>
</xsl:choose>
</xsl:variable>
<fo:table-row bgcolor="{$bgclr}">
<fo:table-cell padding-top="0pt" padding-left="5.4pt" padding-bottom="0pt" padding-right="5.4pt" border-left-style="solid" border-right-style="solid" border-left-color="#FFFFFF" border-right-color="#FFFFFF" border-left-width="0.5pt" border-right-width="1.5pt" border-top-style="solid" border-bottom-style="solid" border-top-color="#FFFFFF" border-bottom-color="#FFFFFF" border-top-width="0.5pt" border-bottom-width="0.5pt">
<fo:block xmlns:st1="urn:schemas-microsoft-com:office:smarttags" space-after="10pt" space-after.conditionality="retain" line-height="1.4911" font-size="9pt" language="EN-US" text-align="left" font-weight="bold" linefeed-treatment="preserve">
<fo:leader leader-length="0pt"/>
<xsl:value-of select="name"/>
</fo:block>
</fo:table-cell>

Edit 3 Input is in JSON format like:

"pdfrequest" : {
        "records" : [{
                "firstname" : "--",
                "lastname" : "--",
                "phoneno" : "--",
                }]
}

      

        
        
        
      

    

Edit 4. Below is the sample XSL I'm using. This turns JSON into pdf. Any help is appreciated.
