具有多个 LineItems 的 Xml 到 Json

问题描述 投票：0回答：1

我正在尝试将 xml 转换为 json，但在 xml 到 json 转换期间未形成多个行项目。我们总是在 xml 消息中包含与 'vpoItemList' 、 'vpoShipDtlDtoGroupList' 和 'vpoShipDtlCsGroupList' 相同名称的单个或多个 Lineitem。

请求检查代码以获取json文件中的所有lineitem作为预期的json文件。收到错误消息：

xml-to-json：重复的键值 {vpoItemList}。

输入xml文件

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

虽然您使用 XSLT 3，但尚不清楚为什么将其标记为 XSLT 2.0。

一般来说，如果您有多个同名的子元素，并且想要将它们“集中”在一起，作为数组成员，在 JSON 表示中，您可以考虑使用 

xsl:for-each-group select="*" group-by="node-name()"
，然后，如果有多个子元素组中的一项（例如 
<xsl:choose><xsl:when test="current-group()[2]">
）输出您需要的数组，否则进行正常处理以构造地图。

我没有完整的、脱离 shell 代码来处理所有选项，使用分组构造数组的示例是

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    exclude-result-prefixes="#all"
    xmlns="http://www.w3.org/2005/xpath-functions"
    expand-text="yes"
    version="3.0">

  <xsl:output method="text"/>

  <xsl:template match="/">
      <xsl:variable name="json-xml">
          <xsl:apply-templates/>
      </xsl:variable>
      <xsl:value-of select="xml-to-json($json-xml, map { 'indent' : true() })"/>
  </xsl:template>
  
  <xsl:template match="*[not(*)]">
    <string key="{local-name()}">{.}</string>
  </xsl:template>
  
  <xsl:template match="*[not(*) and . castable as xs:double]">
    <number key="{local-name()}">{.}</number>
  </xsl:template>
  
  <xsl:template match="*[*]">
      <map>
          <xsl:for-each-group select="*" group-by="node-name()">
              <xsl:choose>
                  <xsl:when test="current-group()[2]">
                      <array key="{local-name()}">
                          <xsl:apply-templates select="current-group()"/>
                      </array>
                  </xsl:when>
                  <xsl:otherwise>
                      <xsl:apply-templates select="current-group()"/>
                  </xsl:otherwise>
              </xsl:choose>
          </xsl:for-each-group>
      </map>
  </xsl:template>

</xsl:stylesheet>

这会改变例如

<root>
    <item>
        <number>3.14</number>
        <name>foo</name>
    </item>
    <item>
        <number>42</number>
        <name>bar</name>
    </item>
    <data>test</data>
</root>

进入

{ "item" : 
    [ 
      { "number" : 3.14,
        "name" : "foo" },
      
      { "number" : 42,
        "name" : "bar" } ],
    "data" : "test" }

您可能需要改进/扩展/适应您的需求。
