在xslt中使用xsl：when

Question

In my XSLT I am outputting customers who have SIM cards involved with country code 49, area code 31 and number 124567. In the When I am outputting any customer who has confirmed identity = 0 in a certain colour which were involved with these numbers.

I need another when which outputs customers who have more than one SIM card in a different colour also involved with the numbers country code 49, area code 31, number 124567. The customers who have more than one SIM card have customerID repeated more than once inside the SIMs/SIM node. I am not sure how to output customers with more than one SIM card in a different colour. I think I need two when s.

Here's how you can make this XSLT much tidier and accomplish what you are describing:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

  <xsl:key name="simsById" match="sim" use="simID" />
  <xsl:key name="customersById" match="customer" use="customerID" />
  <xsl:key name="simsByCustomerId" match="database/sims/sim" 
           use="customerID" />

  <xsl:template match="/">
    <html>
      <head>
        <title>Customers</title>
        <style>
          tr.unconfirmed td { background-color: #FFA500; }
          tr.multisim    td { background-color: Green; }
        </style>
      </head>
      <body>
        <table rules="all">
          <caption>Customers</caption>
          <thead>
            <tr>
              <th>Firstname</th>
              <th>Surname</th>
            </tr>
          </thead>

          <xsl:apply-templates
              select="database/calls/call[countryCodeOfOtherParty  = '49' and
                                          areaCodeOfOtherParty ='31' and 
                                          numberCodeOfOtherParty ='124567']" />
        </table>
      </body>
    </html>
  </xsl:template>

  <xsl:template match="call">
     <xsl:apply-templates select="key('customersById', 
                                      key('simsById', simID)/customerID)" />
  </xsl:template>

  <xsl:template match="customer">
    <tr>
      <xsl:attribute name="class">
        <xsl:apply-templates select="." mode="determineClass" />
      </xsl:attribute>
      <td>
        <xsl:value-of select="firstname"/>
      </td>
      <td>
        <xsl:value-of select="surname"/>
      </td>
    </tr>
  </xsl:template>

  <!-- Below is the part that determines a row's class -->

  <!-- Catch-all for customers with no special formatting -->
  <xsl:template match="customer" mode="determineClass" />

  <xsl:template match="customer[confirmedIdentity = 0]" mode="determineClass">
    <xsl:text>unconfirmed</xsl:text>
  </xsl:template>

  <xsl:template match="customer[key('simsByCustomerId', customerID)[2]]"
                mode="determineClass">
    <xsl:text>multisim</xsl:text>
  </xsl:template>

</xsl:stylesheet>

When run on your sample input, the result is:

<html>
  <head>
    <META http-equiv="Content-Type" content="text/html; charset=utf-8">
    <title>Customers</title>
    <style>
          tr.unconfirmed td { background-color: #FFA500; }
          tr.multisim    td { background-color: Green; }
        </style>
  </head>
  <body>
    <table rules="all">
      <caption>Customers</caption>
      <thead>
        <tr>
          <th>Firstname</th>
          <th>Surname</th>
        </tr>
      </thead>
      <tr class="multisim">
        <td>James</td>
        <td>Brown</td>
      </tr>
      <tr class="multisim">
        <td>Peter</td>
        <td>Brown</td>
      </tr>
      <tr class="">
        <td>Xavier</td>
        <td>Brown</td>
      </tr>
      <tr class="unconfirmed">
        <td>Xavier</td>
        <td>Brown</td>
      </tr>
    </table>
  </body>
</html>
