Exemple Empleats

Codi XML d'una BBDD d'empleats amb sou (empleats.xml): 

<?xml version="1.0" encoding='UTF-8'?>
<?xml-stylesheet href="empleats.xsl" type="text/xsl"?>
<empresa>
  <departament>   
       <empleats> 
          <nom>Eduard</nom>
          <sou>3500</sou>
       </empleats>  
       <empleats>
          <nom>Montse</nom>
          <sou>1250</sou>
       </empleats>   
       <empleats>
          <nom>Lluis</nom>

          <sou>1850</sou>
      </empleats>        
 </departament>
</empresa>


A continuació tenim el codi font del fitxer XSL (empleats.xsl) que executarem per mostrar les dades del XML anterior: 

 <?xml version="1.0" encoding="UTF-8"?>
 <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:template match="/">
   <html>
     <body>
        <table border="1">
        <tr>
           <th>Nom</th>
           <th>Sou</th>
        </tr>
        <xsl:for-each select="empresa/departament/empleats">
          <xsl:choose>
      <!-- sous superiors a 1500 -->
            <xsl:when test="sou > 1500">
                <tr bgcolor="green">
                     <td><xsl:value-of select="nom"/></td>
                     <td><xsl:value-of select="sou"/></td>
                </tr>
            </xsl:when>
      <!-- sous inferiors a 1000 -->
            <xsl:when test="sou < 1000">
                <tr bgcolor="yellow">
                     <td><xsl:value-of select="nom"/></td>
                     <td><xsl:value-of select="sou"/></td>
                </tr>
            </xsl:when>
      <!-- sous entre 1000 i 1500 -->
            <xsl:otherwise>
                <tr bgcolor="grey">
                     <td><xsl:value-of select="nom"/></td>
                     <td><xsl:value-of select="sou"/></td>
                </tr>
            </xsl:otherwise>
          </xsl:choose>
        </xsl:for-each>
       </table>
     </body>
   </html>
  </xsl:template>
 </xsl:stylesheet>


Aquest exemple ens mostrarà una taula on apareixeran els noms i sous dels empleats amb els següents criteris:

  • En groc els empleats amb un sou inferior a 1000
  • En gris els empleats amb un sou entre 1000 i 1500
  • En verd els empleats amb un sou superior a 1500

I el resultat serà quelcom semblant a:

Nom Sou
Eduard 3500
Montse 1250
Lluís 750
Jordi 1850
