输出（实际和期望）：

我认为使用分组方式可能会使事情变得比实际情况更复杂。基本上，对于每一行，您需要遍历所有列并输出单元格（如果存在），否则输出空单元格。这意味着您应该迭代索引而不是行元素：

<xsl:for-each select="1 to $numRows">
    <xsl:variable name="rowIndex" select="position()" />
    <tr>
    <xsl:for-each select="$vCols">
        <xsl:variable name="cell" select="//Row[string(Hostname) = .][position() = $rowIndex]" />
        <xsl:apply-templates select="$cell">
        <xsl:if test="not($cell)">
            <td></td>
        </xsl:if>
    </xsl:for-each>
    <tr>
</xsl:for.each>

首先，我认为您的

maxRows

变量可以简化为

<xsl:variable name="maxRows" select="max(//Row/count(key(hostNameByValue, Hostname)))" />

您还可以使用

不同的值

来获取不同的列名

<xsl:variable name="cols" select="distinct-values(//Row/Hostname)" />

（其中，

$doc

是对初始XML文档的引用，因为在

xsl:for each

中现在是一个原子值序列）

试试这个XSLT

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    exclude-result-prefixes="xs"
    version="2.0">

  <xsl:output method="xml" indent="yes" />

  <xsl:key name="hostNameByValue" match="Row" use="Hostname"/>

  <xsl:variable name="cols" select="distinct-values(//Row/Hostname)" />
  <xsl:variable name="maxRows" select="max(//Row/count(key('hostNameByValue', Hostname)))" />
  <xsl:variable name="doc" select="/" />

  <xsl:template match="DocumentRoot">
    <table>
    <tr>
      <xsl:for-each select="$cols">
        <th><xsl:value-of select="."/></th>
      </xsl:for-each>
      </tr>
      <xsl:for-each select="1 to $maxRows">
        <xsl:variable name="rowNum" select="position()"/>
        <tr>
          <xsl:for-each select="$cols">
            <th><xsl:value-of select="key('hostNameByValue', ., $doc)[position() = $rowNum]/VLAN"/></th>
          </xsl:for-each>
        </tr>
      </xsl:for-each>
    </table>
  </xsl:template>
</xsl:stylesheet>

在

中查看它的实际操作我不认为在XSLT 2或3中，一旦您对每个组使用了

，您就需要任何键，您可以存储分组结果，然后对其进行处理，例如将分组结果作为XML存储在您可以使用的XSLT 2或XSLT 3中
