元素包含一个以管道分隔的字符串；该字符串的组件需要以某种方式成为每个

的元素。此外，这些新元素的值是通过查看

中管道分隔字符串中的相应位置来指定的

我拍摄的整体结构是：

元素的所有属性都转换为子元素

的元素映射到同一位置在

元素中

使用XSLT1.0

因此，以下是我的预期结构：

（请再次注意，我不关心我们用于这些新数据点的字段名[在

]之后开始]；但是，如果您想告诉我如何相对容易地指定某种类型的字段名数组（因为缺少更好的术语），那么您可以获得额外的分数）

下面是我当前的XSLT，它实现了目标#1；我被难倒的目标是#2：

<xsl:stylesheet version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output omit-xml-declaration="no" indent="yes"/>
  <xsl:strip-space elements="*"/>

  <!-- Template #1 - Identity Transform -->
  <xsl:template match="node()|@*">
    <xsl:copy>
      <xsl:apply-templates select="node()|@*"/>
    </xsl:copy>
  </xsl:template>

  <!-- Template #2 - Convert all of a <RECIPE> element's attributes to child elements -->  
  <xsl:template match="RECIPE/@*">
    <xsl:element name="{name()}">
      <xsl:value-of select="." />
    </xsl:element>
  </xsl:template>

  <!-- Template #3 - Remove extraneous text from each <RECIPE> -->  
  <xsl:template match="RECIPE/text()" />

</xsl:stylesheet>

就这样。非常感谢你的帮助

我不是100%确定我理解了你的问题，但我认为你应该看看XSL。如果将其与position（）函数组合在一个变量中，您应该能够获得相关的输出

为了进一步增加这一点，您可以将name（）与a（替换为2.0/translate为1.0）结合在一起，以自动获取元素名称）在a for each中，提取位置。

参考我的实现：-
