org.json无法使用嵌套对象和数组将json转换为xml proper-json对象。需要替代方法

标签： java json xml org.json

我需要将json转换为xml。

我正在使用org.json jar文件

但是，xml中元素的顺序是不同的，并且在转换时也缺少很少的元素。输入消息是带有json数组的嵌套json对象。 对于简单的json到xml，代码工作正常。 请为此问题提供备用方法/库

package jjson;
import java.io.*;
import org.json.JSONObject;
import org.json.XML;
public class Json {

public static void main (String args[]) {
    InputStreamReader is = null;
    BufferedReader br = null;
    StringBuilder sb = null;

    try {

        File jsonFile = new File("<<provide location of file>>");
        is = new InputStreamReader(new FileInputStream(jsonFile), "UTF-8");

        // Read the input stream and covert into string object
        //is = new InputStreamReader(inputStream);
        sb = new StringBuilder();
        br = new BufferedReader(is);
        String read = br.readLine();

        while (read != null) {
            // System.out.println(read);
            sb.append(read);
            read = br.readLine();

        }

        // Convert the String object to XML and write in the default name

        String xml = XML.toString(new JSONObject(sb.toString()));
        System.out.println(xml);
        //String service.write(xml.getBytes(), "default");
    } catch (Exception e) {
        // TODO Auto-generated catch block

    } finally {

        if (br != null) {
            try {
                br.close();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
        if (is != null) {
            try {
                is.close();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }
}
}

以下XSLT 3.0样式表提供了您正在寻找的输出（它使用json-to-xml（）函数进行XML的通用转换，然后将通用XML转换为您需要的特定表单）：

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

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

    <xsl:template name="xsl:initial-template">
        <JSON>
            <xsl:apply-templates select="json-to-xml(unparsed-text('test.json'))"/>
        </JSON>
    </xsl:template>

    <xsl:template match="*[@key[. castable as xs:NCName]]" priority="2">
        <xsl:element name="{@key}">
            <xsl:apply-templates/>
        </xsl:element>       
    </xsl:template>

    <xsl:template match="*[@key[not(. castable as xs:NCName)]]" priority="2">
        <xsl:message terminate="yes">Key {@key} cannot be used as an element name</xsl:message>    
    </xsl:template>

    <xsl:template match="fn:array[@key[. castable as xs:NCName]][exists(*)]" priority="3">
        <xsl:for-each select="*">
            <xsl:element name="{../@key}">
                <xsl:apply-templates select="."/>
            </xsl:element>
        </xsl:for-each>
    </xsl:template>

    <xsl:template match="fn:array[@key[. castable as xs:NCName]][empty(*)]" priority="3">
        <xsl:element name="{@key}"/>
    </xsl:template>

</xsl:stylesheet>
