xml - xslt-1.0 for-each 循环获取所有子元素

问题描述

我是 xsl 的新手。我正在为每个循环而苦苦挣扎。我有以下 input.xml 并且需要预期的 output.xml。但是我得到了所有后续的结果。

输入.xml

<?xml version="1.0" encoding="utf-8" ?>

您可以看到，我想根据 _FOLDER_1 和 _FOLDER_2 将其分为 2 组。当我使用下面的 xsl 代码进行迭代时，我得到了所有结果，并且这些结果没有基于 _FOLDER_1 和 _FOLDER_2 进行区分。

xsl:

<xsl:template match="/">

      <Folder>
    <xsl:for-each select="FOLDER-HIERARCHY/CHILDREN/FOLDER-HIERARCHY/CHILDREN/FOLDER-HIERARCHY/CHILDREN/OBJECT/SPEC-OBJECT-REF">
        <xsl:variable name="specObjectRef" select="."/>

        <ul><xsl:value-of select="$specObjectRef"/></ul>

    </xsl:for-each>
    </Folder>

  </xsl:template>

如果我循环使用 2 个 for 循环外部循环用于 FOLDER 和内部用于子元素，我可以获得所需的结果。但是由于某些原因，我不能使用这种方法，因为我需要在另一个外部循环中使用这些数据。请帮忙。提前致谢。

解决方案

你只需要把你的xsl:for-each分成两部分并嵌套它们。外部将选择 main FOLDER-HIERARCHY，然后Folder为每个创建一个。然后，在其中，您可以选择SPEC-OBJECT-REF

试试这个模板：

<xsl:template match="/">
  <xsl:for-each select="FOLDER-HIERARCHY/CHILDREN/FOLDER-HIERARCHY/CHILDREN/FOLDER-HIERARCHY">
    <Folder>
      <xsl:for-each select="CHILDREN/OBJECT/SPEC-OBJECT-REF">
        <ul><xsl:value-of select="."/></ul>
      </xsl:for-each>
    </Folder>
  </xsl:for-each>
</xsl:template>
