xslt - 嵌套变换

Question

我尝试对以下 XML 执行转换：

<?xml version="1.0" encoding="UTF-8"?>
<A_Example>
    <A_ExampleType>
    
    <RandomData1></RandomData1>

    </A_ExampleType>
</A_Example>

我想实现以下输出：

<A_Example>
    <A_ExampleType>
    
    <RandomData1></RandomData1>
    <RandomData2></RandomData2>
    <RandomData3></RandomData3>

    <RandomData5></RandomData5>
    <RandomData6></RandomData6>
    
    </A_ExampleType>
    
    <A_ExampleType>
    
    <RandomData1></RandomData1>

    <RandomData3></RandomData3>
    <RandomData4></RandomData4>
    <RandomData5></RandomData5>
    <RandomData6></RandomData6>
      
    <RandomData1></RandomData1>
    <RandomData2></RandomData2>
    <RandomData3></RandomData3>

    <RandomData5></RandomData5>
    <RandomData6></RandomData6>
          
    <RandomChildData1></RandomChildData1>
    <RandomChildData2></RandomChildData2>
    <RandomChildData3></RandomChildData3>
    <RandomChildData4></RandomChildData4>
    <RandomChildData5></RandomChildData5>
    <RandomChildData6></RandomChildData6>
            
    <RandomAreaData1></RandomAreaData1>
    <RandomAreaData2></RandomAreaData2>

    <RandomData1></RandomData1>
    <RandomData2></RandomData2>
    <RandomData3></RandomData3>
    <RandomData4></RandomData4>
    <RandomData5></RandomData5>
    <RandomData6></RandomData6>
      
    <RandomData1></RandomData1>
    <RandomData2></RandomData2>
    <RandomData3></RandomData3>
    <RandomData4></RandomData4>
    <RandomData5></RandomData5>
    <RandomData6></RandomData6>
   
    </A_ExampleType>
</A_Example>

简而言之，我想要一个没有嵌套节点的平面结构。我尝试使用以下 XSLT 进行处理，但并没有走得太远。

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:template match="/A_Example">
    <test>
    <xsl:for-each select="//A_ExampleType">
    <hallo>
        <xsl:value-of select="."></xsl:value-of>
    </hallo>
    </xsl:for-each>
    </test>
    </xsl:template>
</xsl:stylesheet>

如果我运行我的代码，我会得到整个数据以及来自所有节点的数据，但没有声明。有了这个，我的意思是我得到了这样的东西。

运行 XSLT 代码之前的 XML：

<RandomData1>Test12345</RandomData1>

运行 XSLT 代码后的 XML 我只得到：

         Test12345

为什么会发生这种情况，我怎样才能取回声明？

当您只想要从第二个嵌套级别（ A_ExampleType ）开始的“叶”节点（没有子节点的节点）时，我会建议以下内容：

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

    <xsl:template match="/A_Example">
        <xsl:copy>
            <xsl:for-each select="A_ExampleType">
                <xsl:copy>
                    <xsl:copy-of select="descendant::*[not(child::*)]"/>
                </xsl:copy>
            </xsl:for-each>
        </xsl:copy>
    </xsl:template>

</xsl:stylesheet>
