JSON 到 XML 转换的 Java 实现

问题描述

是否有现有的 JAR 可用于将 JSON 转换为 XML?

Are there existing JARs available to convert from JSON to XML?

推荐答案

不是 Java，而是 纯 XSLT 2.0 实现:

Not a Java, but a pure XSLT 2.0 implementation:

看看f:json-document() 来自 FXSL 2.x 库.

Have a look at the f:json-document() from the FXSL 2.x library.

使用此功能可以非常轻松地合并 JSon 并将其用作... XML.

Using this function it is extremely easy to incorporate JSon and use it just as... XML.

例如，您可以只编写以下 XPath 表达式:

For example, one can just write the following XPath expression:

f:json-document($vstrParam)/Students/*[sex = 'Female']

和使用sex = 'Female'

以下是完整示例:

<xsl:stylesheet version="2.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:xs="http://www.w3.org/2001/XMLSchema"
 xmlns:f="http://fxsl.sf.net/"
 exclude-result-prefixes="f xs"
 >
 <xsl:import href="../f/func-json-document.xsl"/>

 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:variable name="vstrParam" as="xs:string">
{

  "teacher":{
    "name":
      "Mr Borat",
    "age":
      "35",
    "Nationality":
      "Kazakhstan"
             },


  "Class":{
    "Semester":
      "Summer",
    "Room":
      null,
    "Subject":
      "Politics",
    "Notes":
      "We're happy, you happy?"
           },

  "Students":
    {
      "Smith":
        {"First Name":"Mary","sex":"Female"},
      "Brown":
        {"First Name":"John","sex":"Male"},
      "Jackson":
        {"First Name":"Jackie","sex":"Female"}
    }
    ,


  "Grades":

    {
      "Test":
      [
        {"grade":"A","points":68,"grade":"B","points":25,"grade":"C","points":15},

        {"grade":"C","points":2, "grade":"B","points":29, "grade":"A","points":55},

        {"grade":"C","points":2, "grade":"A","points":72, "grade":"A","points":65}
       ]
    }


}
 </xsl:variable>

 <xsl:template match="/">
    <xsl:sequence select=
     "f:json-document($vstrParam)/Students/*[sex = 'Female']"/>

 </xsl:template>
</xsl:stylesheet>

当上述转换应用于任何 XML 文档(被忽略)时，会产生正确的结果:

<Smith>
   <First_Name>Mary</First_Name>
   <sex>Female</sex>
</Smith>
<Jackson>
   <First_Name>Jackie</First_Name>
   <sex>Female</sex>
</Jackson>
