目前，我正在使用如下所示的 XSLT 样式表，它为我提供了不同的格式。你能帮我修复这个样式表以获得上述格式吗？

<xsl:stylesheet version="3.0" 
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:xs="http://www.w3.org/2001/XMLSchema"
  exclude-result-prefixes="xs"
  expand-text="yes">
  <xsl:template name="xsl:initial-template">
    <xsl:stream href="100.plans.xml">
      <xsl:for-each select="/population/person | /population/person/plan[@selected='yes']/act | /population/person/plan[@selected='yes']/leg">
        {position()},{@id},{@type},{@link},{@x},{@y},{@start_time},{@end_time},{@mode},{@dep_time},{@trav_time},{@arr_time}
      </xsl:for-each>
    </xsl:stream>
  </xsl:template>
</xsl:stylesheet>

这是一个流式示例，它仅将每个/population/person/plan[@selected='yes']及其祖先snapshot()作为兄弟访问以纯流式方式拉入内存是不可能的我认为：

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="3.0" 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    exclude-result-prefixes="xs"
    expand-text="yes">

    <xsl:output method="text"/>

    <xsl:template name="xsl:initial-template">
        <xsl:stream href="100.plans.xml">
            <xsl:for-each select="/population/person/plan[@selected='yes']/snapshot()/act">
                <xsl:variable name="leg" select="following-sibling::*[1][self::leg]" />
                <xsl:value-of select="position(), ../../@id, @type, @link, @x, @y, @start_time, @end_time, string($leg/@mode), string($leg/@dep_time), string($leg/@trav_time), string($leg/@arr_time)" separator=","/>
                <xsl:text>&#10;</xsl:text>
            </xsl:for-each>
        </xsl:stream>
    </xsl:template>

</xsl:stylesheet>

使用 Saxon 9.7 EE 的示例输入的输出是

看起来您实际上想要为每个act元素输出一行，但该行也将包含来自祖先节点person和后续leg节点的信息。这意味着你xsl:for-each应该真的是这样的：

<xsl:for-each select="/population/person/plan[@selected='yes']/act">

要获取person元素的 id，您将执行此操作...

{../../@id}

要从以下leg元素获取信息，您可以定义一个像这样的变量......

 <xsl:variable name="leg" select="following-sibling::*[1][self::leg]" />

然后你从 获取信息leg，你会这样做

{$leg/@mode}

我没有 XSLT 3.0 处理器来测试自己，但在 XSLT 1.0 中，它看起来像这样（我没有包含所有字段以使其更短）

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="text" />
  <xsl:template match="/">
      <xsl:for-each select="/population/person/plan[@selected='yes']/act">
        <xsl:variable name="leg" select="following-sibling::*[1][self::leg]" />
        <xsl:value-of select="position()" />
        <xsl:text>,</xsl:text>
        <xsl:value-of select="../../@id" />
        <xsl:text>,</xsl:text>
        <xsl:value-of select="@type" />
        <xsl:text>,</xsl:text>
        <xsl:value-of select="$leg/@mode" />
        <xsl:text>&#10;</xsl:text>
      </xsl:for-each>
  </xsl:template>
</xsl:stylesheet>

编辑：如果确实所有act元素都有以下leg元素，除了最后一个，试试这个 XSLT

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="text" />
  <xsl:template match="/">
      <xsl:for-each select="/population/person/plan[@selected='yes']/*[self::act|self::leg]">
        <xsl:choose>
          <xsl:when test="self::act">
            <xsl:value-of select="position()" />
            <xsl:text>,</xsl:text>
            <xsl:value-of select="../../@id" />
            <xsl:text>,</xsl:text>
            <xsl:value-of select="@type" />
            <xsl:text>,</xsl:text>
            <xsl:value-of select="@link" />
          </xsl:when>
          <xsl:when test="self::leg">
            <xsl:text>,</xsl:text>
            <xsl:value-of select="@mode" />
            <xsl:text>,</xsl:text>
            <xsl:value-of select="@dep_time" />
            <xsl:text>&#10;</xsl:text>
          </xsl:when>
        </xsl:choose>
      </xsl:for-each>
      <xsl:text>,,&#10;</xsl:text>
  </xsl:template>
</xsl:stylesheet>
