需要将 xhtml 表转换为具有行跨度的 dita 特定表

看来你可以编写模板来匹配和转换不同的 HTML 元素和属性到 target/dita 对应物：

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    exclude-result-prefixes="#all"
    version="3.0">

  <xsl:output method="xml" indent="yes"/>
  <xsl:strip-space elements="*"/>

  <xsl:template match="table">
    <xsl:copy>
      <xsl:apply-templates select="colgroup"/>
    </xsl:copy>
  </xsl:template>
  
  <xsl:template match="colgroup">
    <tgroup cols="{count(col)}">
      <xsl:apply-templates select="col, ../tbody"/>
    </tgroup>
  </xsl:template>
  
  <xsl:template match="col">
    <colspec colname="col{position()}"/>
  </xsl:template>
  
  <xsl:template match="tbody">
    <xsl:copy>
      <xsl:apply-templates/>
    </xsl:copy>
  </xsl:template>
  
  <xsl:template match="tr">
    <row>
      <xsl:apply-templates/>
    </row>
  </xsl:template>
  
  <xsl:template match="th | td">
    <entry>
      <xsl:apply-templates select="@*, node()"/>
    </entry>
  </xsl:template>
  
  <xsl:template match="th/@* | td/@*"/>
  
  <xsl:template match="th/@rowspan[. > 1] | td/@rowspan[. > 1]">
    <xsl:attribute name="morerows" select=". - 1"/>
  </xsl:template>
  
</xsl:stylesheet>

然而，一般来说，对于复杂但定义明确且得到广泛支持的词汇表，如 XHTML 和 Dita，我会查看是否有现有的库来实现手头的任务，而不是尝试自己动手。
