Question

我试图将我的XML样式放入表中，但我根本没有运气。

目前我试图将数据打印到一个表中，但它只打印标题而不是数据，这里出了什么问题？

我的XML格式正确。我的XSL可能有问题

Answer 1

您的脚本失败的原因是您关闭了for-each-group循环太早。它实际上只打印作者 - ＆＃34; head＆＃34;书组。

应构建模板中有关table标记的部分如下：

for-each-group（外部）循环，正如您所做的那样。
作者和标题（2行），就像你一样。
仍然在此外圈中，放置一个for-each循环，循环遍历当前组的内容（特定作者的书籍）。
其内容应输出一行（<tr>标签）并在其中输出4个单元格（<td>标签）具有适当的内容。第一个包含id 当前book的属性，以及其余 - 所选的值儿童标签（标题，流派和价格）。

因此，您的模板应如下所示：

<xsl:template match="catalog">
  <html>
    <head>
      <title>Books Catalog by Author</title>
    </head>
    <body>
      <h1>Books Catalog by Author</h1>
      <table border ="1" cellpadding ="5">
        <xsl:for-each-group select="book" group-by="author">
          <xsl:sort select="current-grouping-key()" />
          <tr bgcolor="#ef9f37">
            <td colspan="4">Author:
              <xsl:value-of select="current-grouping-key()" />
            </td>
          </tr>
          <tr>
            <td>ID</td><td>Title</td><td>Genre</td><td>Price</td>
          </tr>
          <xsl:for-each select="current-group()">
            <tr>
              <td><xsl:value-of select="@id"/></td>
              <td><xsl:value-of select="title"/></td>
              <td><xsl:value-of select="genre"/></td>
              <td><xsl:value-of select="price"/></td>
            </tr>
          </xsl:for-each>
        </xsl:for-each-group>
      </table>
    </body>
  </html>
</xsl:template>

顺便说一句：您的概念是for-each-group按@id分组书籍很奇怪请注意，每本书都有不同 id ，因此没有组会包含超过1本书。

我的XSL怎么了？
