Goal: colour code the different types of CD

• xsl:choose provides an "either or" processing

    <tbody>
      <xsl:for-each select="cdlist/cd">
        <tr>
        <xsl:attribute name="style">color:
          <xsl:choose>
            <xsl:when test="filed[. = 'C05 World']">lime</xsl:when>
            <xsl:when test="filed[. = 'C06 Country']">yellow</xsl:when>
            <xsl:when test="filed[. = 'C11 Jazz Trad']">orange</xsl:when>
            <xsl:when test="filed[. = 'C01 Pop']">red</xsl:when>
            <xsl:otherwise>white</xsl:otherwise>
          </xsl:choose>
        </xsl:attribute>
        <td><xsl:value-of select="artist"/></td>
        <td><xsl:value-of select="title"/></td>
        <td><xsl:value-of select="filed"/></td>
        </tr>
      </xsl:for-each>
    </tbody>

It tests whether the content of the element "filed" is C05 World, C06 Country, etc.
