所有标签都是一级，订单组和xslt中的排序

Question

我有一个XML（销售订单）的问题。我导入一个XML结构的文件（csv）。我使用的工具自动从该文件创建具有相同结构的XML。所有标签都在同一级别。

<?xml version="1.0" encoding="UTF-8"?>
<ORDER>
<ENV>
    <SenderCode>1234</SenderCode>
    <Test>N</Test>
</ENV>
<HDR>
    <OrderNumber>100</OrderNumber>
    <OrderDate>201206080000</OrderDate>
</HDR>
<ROW>
    <LineNumber>1</LineNumber>
    <Article>A</Article>
</ROW>
<ROW>
    <LineNumber>2</LineNumber>
    <Article>B</Article>
</ROW>
<ROW>
    <LineNumber>3</LineNumber>
    <Article>C</Article>
</ROW>
<ROW>
    <LineNumber>4</LineNumber>
    <Article>D</Article>
</ROW>
<HDR>
    <OrderNumber>101</OrderNumber>
    <OrderDate>201206080000</OrderDate>
</HDR>
<ROW>
    <LineNumber>1</LineNumber>
    <Article>E</Article>
</ROW>
<ROW>
    <LineNumber>2</LineNumber>
    <Article>F</Article>
</ROW>
</ORDER>

我需要的输出是：

<?xml version="1.0" encoding="UTF-8"?>
<ORDER>
  <ENV>
    <SenderCode>1234</SenderCode>
    <Test>N</Test>
  </ENV>
  <HDR>
    <OrderNumber>100</OrderNumber>
    <OrderDate>201206080000</OrderDate>
    <ROW>
      <LineNumber>1</LineNumber>
      <Article>A</Article>
    </ROW>
    <ROW>
      <LineNumber>2</LineNumber>
      <Article>B</Article>
    </ROW>
    <ROW>
      <LineNumber>3</LineNumber>
      <Article>C</Article>
    </ROW>
    <ROW>
      <LineNumber>4</LineNumber>
      <Article>D</Article>
    </ROW>
  </HDR>
  <ENV>
    <SenderCode>1234</SenderCode>
    <Test>N</Test>
  </ENV>
  <HDR>
    <OrderNumber>101</OrderNumber>
    <OrderDate>201206080000</OrderDate>
    <ROW>
      <LineNumber>1</LineNumber>
      <Article>E</Article>
    </ROW>
    <ROW>
      <LineNumber>2</LineNumber>
      <Article>F</Article>
    </ROW>
  </HDR>
</ORDER>

我怎么能用XSLT做到这一点？当我尝试这个时，所有六个ROW标签都在HDR（1）和HDR（2）下。

<?xml version="1.0" encoding="UTF-8"?>
<ORDER>
<ENV>
    <SenderCode>1234</SenderCode>
    <Test>N</Test>
</ENV>
<HDR>
    <OrderNumber>100</OrderNumber>
    <OrderDate>201206080000</OrderDate>
    <ROW>
        <LineNumber>1</LineNumber>
        <Article>A</Article>
    </ROW>
    <ROW>
        <LineNumber>2</LineNumber>
        <Article>B</Article>
    </ROW>
    <ROW>
        <LineNumber>3</LineNumber>
        <Article>C</Article>
    </ROW>
    <ROW>
        <LineNumber>4</LineNumber>
        <Article>D</Article>
    </ROW>
    <ROW>
        <LineNumber>1</LineNumber>
        <Article>E</Article>
    </ROW>
    <ROW>
        <LineNumber>2</LineNumber>
        <Article>F</Article>
    </ROW>
</HDR>
<ENV>
    <SenderCode>1234</SenderCode>
    <Test>N</Test>
</ENV>
<HDR>
    <OrderNumber>101</OrderNumber>
    <OrderDate>201206080000</OrderDate>
    <ROW>
        <LineNumber>1</LineNumber>
        <Article>A</Article>
    </ROW>
    <ROW>
        <LineNumber>2</LineNumber>
        <Article>B</Article>
    </ROW>
    <ROW>
        <LineNumber>3</LineNumber>
        <Article>C</Article>
    </ROW>
    <ROW>
        <LineNumber>4</LineNumber>
        <Article>D</Article>
    </ROW>
    <ROW>
        <LineNumber>1</LineNumber>
        <Article>E</Article>
    </ROW>
    <ROW>
        <LineNumber>2</LineNumber>
        <Article>F</Article>
    </ROW>
</HDR>
</ORDER>

有人能帮助我吗？

谢谢

这种转变将按照你的要求进行。它使用一个键来识别每个ROW之后的所有HDR元素。

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

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

  <xsl:key name="row-by-hdr-id" match="ROW" use="generate-id(preceding-sibling::HDR[1])"/>

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

  <xsl:template match="/ORDER">
    <xsl:copy>
      <xsl:apply-templates select="HDR"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="HDR">
    <xsl:apply-templates select="preceding-sibling::ENV"/>
    <xsl:copy>
      <xsl:apply-templates/>
      <xsl:apply-templates select="key('row-by-hdr-id', generate-id())"/>
    </xsl:copy>
  </xsl:template>

</xsl:stylesheet>
