xml 到 json 的转换 - [[]] 的附加方括号用于 lineitems 和 line item

分类：编程问答

如何解决xml 到 json 的转换 - [[]] 的附加方括号用于 lineitems 和 line item

我们有 1 个或超过 1 个订单项。

即使对于“vpoItemList”的单行项目或多行项目也需要方括号：[和子行项目“vpoItemcslist”：[

用于 (vpoShipDtlDtoGroupList & vpoShipDtlCsGroupList) 的单个或多个行项目的附加方括号。

“vpoShipDtlCsGroupList”应根据以下预期的 json 文件为每个订单项添加方括号。 "vpoShipDtlCsGroupList": [[{....}],[{...}]]

解决方法

代码的改编需要检查分组代码中的那些元素：

<?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]">
