Convert xml to json with Java

Question

Is there a way to convert a xml file to json? The XML can be of any structure, therefore there is no POJO class for instantiation. I need to convert the xml to json or to a Map, without root nodes.

For example:

<import name="person">
    <item>
        <firstName>Emil</firstName>
        <lastName>Example</lastName>
        <addresses>
            <address>
                <street>Example Blvd.</street>
            </address>
            <address>
                <street>Example Ave.</street>
            </address>
        </addresses>
    </item>
</import>

Expected JSON

{
    "firstName": "Emil",
    "lastName": "Example",
    "addresses": [
        { "street" : "Example Blvd." },
        { "street" : "Example Ave." }
    ]
}

I am used JSON-java but I found more Efficient Library to Convert XML to Json is XmlToJson

Which is Given Best Customization to making Json fromXML

Add the libary dependency to your APP build.gradle file

dependencies {
compile 'com.github.smart-fun:XmlToJson:1.4.4'    // add this line
}

---

    <?xml version="1.0" encoding="utf-8"?>
    <library>
    <book id="007">James Bond</book>
    <book id="000">Book for the dummies</book>
    </library>

• Custom Content names

  public String convertXmlToJson(String xml) {
  XmlToJson xmlToJson = new XmlToJson.Builder(xml)
      .setContentName("/library/book", "title")
      .build();
  return xmlToJson.toString();
  }
  

  ---

  "library":{  
    "book":[  
       {  
          "id":"007",
          "title":"James Bond"
       },
       {  
          "id":"000",
          "title":"Book for the dummies"
       }
     ]
    }
   }

• Custom Attributes names

  public String convertXmlToJson(String xml) {
    XmlToJson xmlToJson = new XmlToJson.Builder(xml)
      .setAttributeName("/library/book/id", "code")
      .build();
    return xmlToJson.toString();
  }
  

  ---

  {  
    "library":{  
    "book":[  
       {  
          "code":"007",
          "content":"James Bond"
       },
       {  
          "code":"000",
          "content":"Book for the dummies"
       }
    ]
   }
  }
