使用 XSLT 将 XML 转换为 JSON 并添加 2 个方括号 [[]]

分类：编程问答

如何解决使用 XSLT 将 XML 转换为 JSON 并添加 2 个方括号 [[]]

请求分享xml到json转换的xslt代码。 我们需要将 xml 转换为 json。然后修剪 OuterElement 和多个方括号 [[ a) 修剪外部元素 b) 带有 2 个方括号的最后 2 个 lineitems(ShipmentRefference,ShipGroupList) [[

输入xml文件：

解决方法

这基本上是从 XML 到 xml-to-json 函数期望的 XML 格式的两步转换。你会用

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

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

  <xsl:mode on-no-match="shallow-skip"/>
  
  <xsl:template match="/*">
    <map>
      <xsl:apply-templates/>
    </map>
  </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="*[* and not(*[2])]">
    <map key="{local-name()}">
        <xsl:apply-templates/>
    </map>
  </xsl:template>
  
  <xsl:template match="*[* and *[2]]">
    <array key="{local-name()}">
        <map>
          <xsl:apply-templates/>
        </map>
    </array>
  </xsl:template>
  
  <xsl:template match="ShipGroupList | ShipmentRefference" priority="10">
    <array key="{local-name()}">
        <array>
          <map>
            <xsl:apply-templates/>
          </map>          
        </array>
    </array>
  </xsl:template>

  <xsl:template match="/" name="xsl:initial-template">
    <xsl:next-match/>
    <xsl:comment xmlns:saxon="http://saxon.sf.net/">Run with {system-property('xsl:product-name')} {system-property('xsl:product-version')} {system-property('Q{http://saxon.sf.net/}platform')}</xsl:comment>
  </xsl:template>

</xsl:stylesheet>

对于给出 (https://xsltfiddle.liberty-development.net/asoTJB/0) 例如的第一步

<?xml version="1.0" encoding="UTF-8"?>
<array xmlns="http://www.w3.org/2005/xpath-functions" key="PO_Message">
   <map>
      <string key="domainId">Mail</string>
      <string key="hubId">Mail</string>
      <array key="MailItemList">
         <map>
            <string key="itemNo">2021-0002</string>
            <string key="itemName">Camp</string>
            <map key="factId">
               <number key="factCode">188</number>
            </map>
         </map>
      </array>
      <array key="ShipGroupList">
         <array>
            <map>
               <number key="GroupList1">123</number>
               <number key="qty">160</number>
               <map key="shipMode">
                  <number key="code">3</number>
               </map>
            </map>
         </array>
      </array>
      <array key="ShipmentRefference">
         <array>
            <map>
               <number key="itemLotNo">199791</number>
               <number key="shipmentNo">1</number>
            </map>
         </array>
      </array>
   </map>
</array>
<!--Run with SAXON HE 9.8.0.15 -->

然后一个完整的样式表将使用变量中的第一步并将 xml-to-json 函数应用于变量：

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

  <xsl:output method="text"/>

  <xsl:template match="/*" priority="5">
    <xsl:variable name="json-xml">
      <map>
        <xsl:apply-templates/>
      </map>        
    </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="*[* and not(*[2])]">
    <map key="{local-name()}">
        <xsl:apply-templates/>
    </map>
  </xsl:template>
  
  <xsl:template match="*[* and *[2]]">
    <array key="{local-name()}">
        <map>
          <xsl:apply-templates/>
        </map>
    </array>
  </xsl:template>
  
  <xsl:template match="ShipGroupList | ShipmentRefference" priority="10">
    <array key="{local-name()}">
        <array>
          <map>
            <xsl:apply-templates/>
          </map>          
        </array>
    </array>
  </xsl:template>

</xsl:stylesheet>
