（首先关闭：我非常抱歉你必须看看这个文档结构;它很可怕）
我有以下XML文档：
<MENUS>

</MENUS>
<NUTRIENTS>元素包含管道分隔的字符串;这个字符串的组件需要以某种方式成为每个<RECIPE>的元素。此外，通过查看<RECIPE>\<nutrients>中找到的管道分隔字符串中的相应位置来指定这些新元素的值。
我正在拍摄的整体结构是：
<RECIPE>元素的所有属性都将转换为子元素。<RECIPE>/<nutrients>的元素映射到同一位置
在<NUTRIENTS>元素内。所以，这是我预期的结构：

（再次注意，我不关心我们用于这些新数据点的字段名称[在<nutrientsuncertain>之后开始];但是，如果您想告诉我如何相对容易指定某种类型的数组，因为没有更好的术语，字段名称）
这是我目前的XSLT，它实现了目标＃1;它的目标＃2让我难以接受：
<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>
就是这样。非常感谢你的帮助！

答案 1 :(得分：0)
我不是100％确定我理解你的问题，但我认为你应该看看XSL tokenize function。如果将变量与position（）函数结合使用，您应该能够实现相关输出吗？
要进一步添加到此，您可以将名称（）与（替换为2.0 / translate for 1.0）组合以在for-each中自动获取元素名称，从而提取位置。
