XSLT - 如何在使用流从变量节点进行内部循环时复制父节点？
XSLT - How can I copy parent node when inside loop from a variable node using streaming?
在迭代循环中使用模板匹配进行流式传输时，我正在努力复制我的父节点数据，该路径来自另一个 xml 我通过地图访问。
我得到的是：
<?xml version='1.0' encoding='utf-8'?>
<root>
<row>
<Record>1</Record>
<Employee-ID>12345</Employee-ID>
<Authorization-ID>133746</Authorization-ID>

<Quantity>2</Quantity>
<Task-ID>PRJTASK0011134</Task-ID>
<Project-Plan-ID>133746-GP OM Internal Labor-1</Project-Plan-ID>
<Comments/>
<Status>Error: Invalid ID value. '' is not a valid ID value for type =

Labor-1' is not a valid ID value for type = 'Project_Plan_ID'. Error: Invalid ID value.
'12345' is not a valid ID value for type = 'Employee_ID'.</Status>

以优化方式实现我想要的输出的最佳方法是什么？
我认为
的结果
<xsl:apply-templates select="errorGroup"/>
将是一个 errorGroup 元素，这意味着 map:get($lineKey, Record) 的结果将是一个 errorGroup 元素，这意味着 map:get($lineKey, Record)/errorGroup 将 select 没有（因为 errorGroup 元素没有 errorGroup 子元素）。尝试将映射的类型声明更改为as="map(xs:string, element(errorGroup))"以加强类型检查。
这是我在快速代码检查中唯一注意到的事情，但您没有告诉我们它是如何失败的；很难诊断一个看不见的问题。
我认为这是 xsl:merge 的任务（至少如果行和错误按 lineNumber 和 Record 整数值排序）：
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

运行 Saxon EE 使用 -it 选项而不是 -s 源选项。
修复原代码，我觉得不是
<xsl:when test="map:contains($lineKey, Record)">
<xsl:iterate select="map:get($lineKey, Record)/errorGroup/errorRow">
<row>

<xsl:apply-templates/>

你想要例如

<xsl:when test="map:contains($lineKey, Record)">

<xsl:apply-templates select="$record">
<xsl:with-param name="status" select="severity || ': ' || message || '.'"/>
</xsl:apply-templates>
</xsl:iterate>
</xsl:when>
加一个模板（范围内需要 expand-text="yes"）
<xsl:template match="row/*[last()]">
<xsl:param name="status"/>
<xsl:next-match/>
<status>{$status}</status>
