XSL技术实现：根据XML子节点不同值生成多张表格

Alright, let's tackle this problem—you want to split your XML album entries into separate tables based on the value of a specific child node (like Country, which is present in your sample). XSLT is the perfect tool for this, and here's a practical, customizable solution:

XSLT Code to Generate Grouped Tables #

We'll use Country as the grouping key (you can swap this out for Artist or any other node if needed):

<?xml version="1.0" encoding="ISO8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

  <!-- Create an index to group albums by their Country value -->
  <xsl:key name="albums-by-country" match="Album" use="Country"/>

  <xsl:template match="/Albums">
    <html>
      <body>
        <!-- Loop through each unique Country value -->
        <xsl:for-each select="Album[generate-id() = generate-id(key('albums-by-country', Country)[1])]">
          <!-- Optional: Sort countries alphabetically for cleaner output -->
          <xsl:sort select="Country"/>

          <!-- Heading for the current country's table -->
          <h2>Albums from <xsl:value-of select="Country"/></h2>

          <!-- Table structure for the country's albums -->
          <table border="1">
            <tr>
              <th>Album Name</th>
              <th>Artist</th>
            </tr>
            <!-- Populate table with all albums in this country group -->
            <xsl:for-each select="key('albums-by-country', Country)">
              <tr>
                <td><xsl:value-of select="Name"/></td>
                <td><xsl:value-of select="Artist"/></td>
              </tr>
            </xsl:for-each>
          </table>
          <br/> <!-- Add spacing between tables -->
        </xsl:for-each>
      </body>
    </html>
  </xsl:template>

</xsl:stylesheet>

How This Works #

• <xsl:key>: Builds an efficient index of all albums grouped by their Country value, so we don't have to scan the entire XML repeatedly.
• generate-id() Check: Ensures we only create one table per unique country (no duplicate tables for the same region).
• Customizable Grouping: If you want to group by Artist instead, just replace every instance of Country with Artist in the code.
• Sorting: The <xsl:sort> tag organizes groups alphabetically—remove it if you prefer the original order from the XML.
