规则： 对于合并行：将主合并单元格的内容复制到合并行中的其他单元格。 在这种情况下，你能帮我解决吗？ 我是xslt的新手。

提前致谢。

答案 0 :(得分：0)

您还没有在问题中详细说明规则，但在我看来，如果任何包含rowmerged="T" 的单元格，则可以实现您要求的输出并清空Para，您将Para从最近的前一行中相应的单元格中复制，但不是空的。

您可以像往常一样使用身份模板启动，该模板默认复制所有未更改的内容，但允许您覆盖特定节点的此行为：

  <xsl:template match="@*|node()">
    <xsl:copy><xsl:apply-templates select="@*|node()"/></xsl:copy>
  </xsl:template>

现在我们要进行更改：对于CELL元素，我们需要修复其属性

  <xsl:template match="CELL">
    <CELL rowmerged="F" rowspan="1">
      <xsl:apply-templates select="node()"/><!-- process children -->
    </CELL>
  </xsl:template>

对于行格式化单元格中的空Para 

  <xsl:template match="Para[not(normalize-space())][../@rowmerged='T']">

我们希望找到匹配单元格不为空的最近的前一行，并复制

    <!-- find the number of this cell in the current row -->
    <xsl:variable name="cellnum" select="count(../preceding-sibling::CELL) + 1" />
    <!-- look for the corresponding Para in previous rows -->
    <xsl:variable name="matchingCells" select="
        ../../preceding-sibling::ROW/CELL[$cellnum]/Para" />
    <!-- filter for just the non-empty ones, and copy the nearest (last in doc order) -->
    <xsl:copy-of select="$matchingCells[normalize-space()][last()]" />

完整的样式表如下：

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

  <xsl:template match="@*|node()">
    <xsl:copy><xsl:apply-templates select="@*|node()"/></xsl:copy>
  </xsl:template>

  <xsl:template match="CELL">
    <CELL rowmerged="F" rowspan="1">
      <xsl:apply-templates select="node()"/>
    </CELL>
  </xsl:template>

  <xsl:template match="Para[not(normalize-space())][../@rowmerged='T']">
    <xsl:variable name="cellnum" select="count(../preceding-sibling::CELL) + 1" />
    <xsl:variable name="matchingCells" select="
        ../../preceding-sibling::ROW/CELL[$cellnum]/Para" />
    <xsl:copy-of select="$matchingCells[normalize-space()][last()]" />
  </xsl:template>
</xsl:stylesheet>
