XSLT <xsl:choose> ແຜນສະຖານີ

XSLT <xsl:choose> ສະມາຊິກຂອງ XSLT ຖືກນຳໃຊ້ເພື່ອປະສົມ <xsl:when> ແລະ <xsl:otherwise> ເພື່ອສະແດງການກວດກາສຳຄັນຫຼາຍອັນ.

<xsl:choose> ສະມາຊິກ

ວິນຍານ

<xsl:choose>
  <xsl:when test="expression">
    ... ອອກສຽງ ...
  </xsl:when>
  <xsl:otherwise>
    ... ອອກສຽງ ...
  </xsl:otherwise>
</xsl:choose>

ບ່ອນທີ່ຕິດຕັ້ງເງື່ອນໄຂການເລືອກ:

ເພື່ອເອົາການກວດກາສຳຄັນຫຼາຍອັນໃນ ສະແພດ XML, ຂ້ອຍຈະສະເໜີ <xsl:choose>、<xsl:when> ແລະ <xsl:otherwise> ໃຫ້ເອົາ:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
  <html>
  <body>
    <h2>My CD Collection</h2>
    <table border="1">
      <tr bgcolor="#9acd32">
        <th>Title</th>
        <th>Artist</th>
      </tr>
      <xsl:for-each select="catalog/cd">
      <tr>
        <td><xsl:value-of select="title"/></td>
      	<xsl:choose>
          <xsl:when test="price > 10">
            <td bgcolor="#ff00ff">
            <xsl:value-of select="artist"/></td>
          </xsl:when>
          <xsl:otherwise>
            <td><xsl:value-of select="artist"/></td>
          </xsl:otherwise>
        </xsl:choose>
      </tr>
      </xsl:for-each>
    </table>
  </body>
  </html>
</xsl:template>
</xsl:stylesheet>

ການຂັບເຄື່ອງກະພິບຢູ່ໃນບໍລິເວນ "Artist" ທີ່ລາຄາ CD ມີຫຼາຍກວ່າ 10 ຈະມີສີສີຂຽວ.

The above conversion results are similar to this:

ຕົວຢ່າງອີກຫນັງຄັ້ງ:

ນີ້ແມ່ນລາຍການຂອງ <xsl:when> ອີກຫນັງຄັ້ງ:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
  <html>
  <body>
    <h2>My CD Collection</h2>
    <table border="1">
      <tr bgcolor="#9acd32">
        <th>Title</th>
        <th>Artist</th>
      </tr>
      <xsl:for-each select="catalog/cd">
      <tr>
        <td><xsl:value-of select="title"/></td>
      	<xsl:choose>
          <xsl:when test="price > 10">
            <td bgcolor="#ff00ff">
            <xsl:value-of select="artist"/></td>
          </xsl:when>
          <xsl:when test="price > 9">
            <td bgcolor="#cccccc">
            <xsl:value-of select="artist"/></td>
          </xsl:when>
          <xsl:otherwise>
            <td><xsl:value-of select="artist"/></td>
          </xsl:otherwise>
        </xsl:choose>
      </tr>
      </xsl:for-each>
    </table>
  </body>
  </html>
</xsl:template>
</xsl:stylesheet>

The above code will add a pink background color to the "Artist" column when the price of the CD is higher than 10, and add a gray background color to the "Artist" column when the price of the CD is higher than 9 and less than or equal to 10.

The above conversion results are similar to this:
