运行 foreach 在已解析的 JSON 嵌套数组上

Question

使用已解析的 JSON 文件作为数据输入构建 table。 JSON 数组中的每个值都应该被分发，同时当运行代码将 JSON 数组中的两个值注入到相同的元素 xml 值中。

在我构建“xsl:element”的代码区域中，我可以在以下内容之间手动切换，一次给我一个数组内容，但我不明白如何让代码遍历数组数据：

<xsl:value-of select="*[1]"/>
<xsl:value-of select="*[2]"/>

JSON:

<data>
{
  "balance-sheets": {
    "sheet-results": {
      "sales": {"values": [3, 5], "title": "Annual sales summary"},
      "costs": {"values": [7, 9], "title": "Accumulated costs per year"}
    }
  }
}
</data>

XSL:

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

<xsl:transform version="3.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:ix="http://www.example.org/1"
  xmlns:se="http://www.example.org/2"
  expand-text="yes"
>

  <xsl:output method="xml" indent="yes"/>

  <!-- Block all data that has no user defined template -->
  <xsl:mode on-no-match="shallow-skip"/>

  <xsl:attribute-set name="base">
    <xsl:attribute name="name">se:{parent::*/@key}</xsl:attribute>
  </xsl:attribute-set>

  <!-- Parse JSON file content to XML map -->
  <xsl:template match="data">
    <store>
      <xsl:apply-templates select="json-to-xml(.)/*"/>
    </store>
  </xsl:template>

  <xsl:template match="*[@key='sheet-results']">

    <table>

        <xsl:for-each select="*">

          <tr>

          <td>
            <xsl:value-of select="*[2]"/>
          </td>

          <xsl:for-each select="*">

            <td>
              <span>

                <xsl:element
                  name="ix:nonFraction"
                  use-attribute-sets="base"
                  >
                  <xsl:value-of select="*"/>
                </xsl:element>
              </span>
            </td>

          </xsl:for-each>

      </tr>

        </xsl:for-each>

    </table>

  </xsl:template>

</xsl:transform>

结果：

<?xml version="1.0" encoding="UTF-8"?>
<store xmlns:ix="http://www.example.org/1" xmlns:se="http://www.example.org/2">
   <table>
      <tr>
         <td>Annual sales summary</td>
         <td>
            <span>
               <ix:nonFraction name="se:sales">3 5</ix:nonFraction>
            </span>
         </td>
         <td>
            <span>
               <ix:nonFraction name="se:sales"/>
            </span>
         </td>
      </tr>
      <tr>
         <td>Accumulated costs per year</td>
         <td>
            <span>
               <ix:nonFraction name="se:costs">7 9</ix:nonFraction>
            </span>
         </td>
         <td>
            <span>
               <ix:nonFraction name="se:costs"/>
            </span>
         </td>
      </tr>
   </table>
</store>

想要的结果：

<?xml version="1.0" encoding="UTF-8"?>
<store xmlns:ix="http://www.example.org/1" xmlns:se="http://www.example.org/2">
   <table>
      <tr>
         <td>Annual sales summary</td>
         <td>
            <span>
               <ix:nonFraction name="se:sales">3</ix:nonFraction>
            </span>
         </td>
         <td>
            <span>
               <ix:nonFraction name="se:sales">5</ix:nonFraction>
            </span>
         </td>
      </tr>
      <tr>
         <td>Accumulated costs per year</td>
         <td>
            <span>
               <ix:nonFraction name="se:costs">7</ix:nonFraction>
            </span>
         </td>
         <td>
            <span>
               <ix:nonFraction name="se:costs">9</ix:nonFraction>
            </span>
         </td>
      </tr>
   </table>
</store>

Answer 1

考虑以下简化示例：

XSLT 3.0

<xsl:stylesheet version="3.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:js="http://www.w3.org/2005/xpath-functions"
exclude-result-prefixes="js">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>

<xsl:template match="/">
    <table>
        <xsl:for-each select="json-to-xml(data)/js:map/js:map/js:map/js:map">
            <tr>
                <th>
                    <xsl:value-of select="js:string[@key='title']"/>
                </th>
                <xsl:for-each select="js:array[@key='values']/js:number">
                    <td>
                        <xsl:value-of select="."/>
                    </td>
                </xsl:for-each>
            </tr>
        </xsl:for-each>
    </table>
</xsl:template>

</xsl:stylesheet>

应用于您的输入示例，这将 return:

结果

<?xml version="1.0" encoding="UTF-8"?>
<table>
   <tr>
      <th>Annual sales summary</th>
      <td>3</td>
      <td>5</td>
   </tr>
   <tr>
      <th>Accumulated costs per year</th>
      <td>7</td>
      <td>9</td>
   </tr>
</table>
