如何计算和评估 XML 中的节点以在 HTML table 中创建行跨度值？

Question

我有一份 xml 文件。我有一些节点。 1.Management（有一些 Upravlinnya），2.Upravlinnya（有一些 viddils）并且 viddils（就像部门）包含一些工人我解决了我的问题，正如您只能通过 viddils 看到的那样。但我实际上不知道为什么它对其他人不起作用。我的 Table 输出（现在）： table

以及它应该如何 how should be 我的 Xslt 文档

感谢帮助）我期待着您的解决方案！）感觉只需要改几行

Answer 1

关键是能够针对您要构建的每一行，查明是否应该为单元格添加一个覆盖其后代行的行跨度，您正试图这样做：

<xsl:if test="position() = 1">

但该测试仅在 Worker 上下文中运行，因此实际上您的逻辑如下所示：

<xsl:if test="Worker first in Viddil">
  <td rowspan="{last()}">
    <xsl:value-of select="ancestor::Management[1]/ManagementName"/>
  </td>
</xsl:if>

<xsl:if test="Worker first in Viddil">
  <td rowspan="{last()}">
    <xsl:value-of select="ancestor::Upravlinnya[1]/UpravlinnyaName"/>
  </td>
</xsl:if>

<xsl:if test="Worker first in Viddil">
  <td rowspan="{last()}">
    <xsl:value-of select="ancestor::Viddil[1]/ViddilName"/>
  </td>
</xsl:if>

这就是为什么只有 Viddil 看起来是正确的，因为逻辑只对 Viddil 是正确的；同样的 Viddil-only 逻辑被应用到 Management 和 Upravlinnya，它看起来是错误的。

在我的版本中，我仍在从 Worker 的上下文中进行测试，但我正在“返回 up 树”到最近的重要祖先，并且问那个祖先是不是第一个。我正在使用 ancestor 和 preceding-sibiling 轴的组合来做到这一点：

<xsl:variable 
    name="firstUpravlinnya"
    select="count(ancestor::Upravlinnya/preceding-sibling::Upravlinnya) = 0"/>

上面说的是，“作为工人，找到我的 Upravlinnya，我的 Upravlinnya 是我管理的所有 Upravlinnya 中的第一个 Upravlinnya（没有兄弟姐妹 before/preceding 它）？”

我还选择不在嵌套的 for-each 循环中全部执行此操作，这样可以工作，但会变得难以阅读。这利用了 XSLT 的自然模板匹配特性来遍历一棵节点树：

这样试试：

XSLT 1.0

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>

<xsl:template match="/Managements">
    <html>
        <body>
            <table border="1">
                <tr>
                    <th>Management Name</th>
                    <th>Upravlinnya Name</th>
                    <th>Viddil Name</th>
                    <th>Name</th>
                    <th>Surname</th>
                    <th>Birth Year</th>
                </tr>
                <xsl:apply-templates select="Management"/>
            </table>
        </body>
    </html>
</xsl:template> 

<xsl:template match="Management">
    <tr>
        <td rowspan="{count(Upravlinnyas/Upravlinnya) + count(Upravlinnyas/Upravlinnya/Viddils/Viddil) + count(Upravlinnyas/Upravlinnya/Viddils/Viddil/Workers/Worker) + 1}">
            <xsl:value-of select="ManagementName"/>
        </td>   
    </tr>
    <xsl:apply-templates select="Upravlinnyas/Upravlinnya"/>
</xsl:template> 

<xsl:template match="Upravlinnya">
    <tr>
        <td rowspan="{count(Viddils/Viddil) + count(Viddils/Viddil/Workers/Worker) + 1}">
            <xsl:value-of select="UpravlinnyaName"/>
        </td>   
    </tr>
    <xsl:apply-templates select="Viddils/Viddil"/>
</xsl:template> 

<xsl:template match="Viddil">
    <tr>
        <td rowspan="{count(Workers/Worker) + 1}">
            <xsl:value-of select="ViddilName"/>
        </td>   
    </tr>
    <xsl:apply-templates select="Workers/Worker"/>
</xsl:template> 

<xsl:template match="Worker">
    <tr>
        <td>
            <xsl:value-of select="WorkerName"/>
        </td>
        <td>
            <xsl:value-of select="WorkerSurname"/>
        </td>
        <td>
            <xsl:value-of select="BirthYear"/>

渲染

请注意，这不是严格正确的解决方案。理想情况下，每个部分的第一行应包含 table 中每一列的单元格，同样，每个小节的第一行应包含剩余到右侧的每一列的单元格小节的列。

因此，结果略有偏差：同一行中单元格的上边框没有完全对齐。但是，我相信为如此简单的代码付出的代价很小。
