目前，我正在使用下面显示的XSLT样式表，它给出了不同的格式。你能帮我修一下这个样式表来获得上述格式吗？

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}

这是一个流式采样，只使用Comparator<Player>将每个/population/person/plan[@selected='yes']及其祖先拉入内存，因为我认为不可能以纯流方式访问兄弟：
snapshot()Saxon 9.7 EE的样本输入输出
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="3.0"

答案 1 :(得分：1)
看起来您实际上想要为每个act元素输出一行，但该行还将包含来自祖先person和leg个节点的信息。这意味着你xsl:for-each应该是这样的：
<xsl:for-each select="/population/person/plan[@selected='yes']/act">
要获取person元素的ID，您可以执行此操作...
{../../@id}
要从以下leg元素获取信息，您可以定义一个类似的变量...
<xsl:variable name="leg" select="following-sibling::*[1][self::leg]" />
然后你要从leg获取信息，你会这样做
{$leg/@mode}
我没有XSLT 3.0处理器来测试自己，但是在XSLT 1.0中，它看起来像这样（我没有包括所有字段以使它更短）
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" />
<xsl:template match="/">
<xsl:for-each select="/population/person/plan[@selected='yes']/act">
<xsl:variable name="leg" select="following-sibling::*[1][self::leg]" />
<xsl:value-of select="position()" />
<xsl:text>,</xsl:text>
<xsl:value-of select="../../@id" />
<xsl:text>,</xsl:text>
<xsl:value-of select="@type" />
<xsl:text>,</xsl:text>
<xsl:value-of select="$leg/@mode" />
<xsl:text> </xsl:text>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
编辑：如果所有act元素确实存在除最后一个元素之外的leg个元素，请尝试使用此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> </xsl:text>
</xsl:when>
</xsl:choose>
</xsl:for-each>
<xsl:text>,, </xsl:text>
</xsl:template>
</xsl:stylesheet>
