使用XSLT将XML平面化为嵌套

在这件事上花了太多时间….“f$%” 希望你能分享你的经验。 我有来自外部数据库的源平面XML，其结构如下：

 <?xml version="1.0" encoding="utf-8"?>
    <ns:MT_ActualCosts xmlns:ns="http://percite:scmaster/actual_costs">
        <row>
            <EVENT_ID>106</EVENT_ID>

    </ns:MT_ActualCosts>


My requested Target Structure should be something like this:

[![enter image description here][1]][1]

I need to group under the Header segments RecordLine Segments of the same `EVENT_ID`.

Currently my XSLT can't create the needed structure.
this is my XSLT:

    <?xml version="1.0" encoding="UTF-8"?>
    <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

当您编写要对元素进行分组的代码时，我想作为一个起点，您可以对每个组使用
，而不是对每个
使用
：

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0"
xmlns:ns0="http://percite:scmaster/actual_costs">

    <xsl:output indent="yes"/>

    <xsl:template match="@*|node()">
        <xsl:copy copy-namespaces="no">
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="/*">
        <ns0:MT_ActualCostPreNormalized>
          <xsl:for-each-group select="row" group-by="EVENT_ID">
              <Header>
                  <xsl:apply-templates select="EVENT_ID, LINE_NUMBER, current-group()"/>
              </Header>
          </xsl:for-each-group>
        </ns0:MT_ActualCostPreNormalized>
    </xsl:template>

    <xsl:template match="row">
        <RecordLine>
            <xsl:apply-templates/>
        </RecordLine>
    </xsl:template>
</xsl:transform>



您可以在
apply templates
中的
标题下列出您想要的更多元素，因为您使用的是XSLT 2.0，所以可以使用
xsl:for each group
（）按
事件ID
分组

另外，使用可以处理所有不需要更改的元素

例如

XML输入

丹尼尔，谢谢你的解决方案。似乎在某个地方，由于某种原因，数据开始混乱。看看EVENT_ID=105。嗨，马丁，谢谢你的代码。如何消除行数为0的行，因为它们表示我不想包含在记录行中的标题段。（保持数据完整性）如果您根本不想对它们进行分组，请将
更改为
。如果您想按事件ID将它们分组，但不想将它们作为
记录行
包含在
标题
元素中，那么请将
更改为
嗨，我相信复制的原因是它复制了行号“0”也表示记录行中的标题。在这种情况下，您可以将内部
更改为
或
。如果你仍然有问题，然后考虑编辑你的问题，并显示出你想要的结果作为一个代码样本，恐怕屏幕截图不足以告诉我们你想包括哪些元素，哪些不是。马丁，我尽我最大的努力（在四方限制），以添加一些MROE数据在我的箱子。希望这可以帮助…
