Yes, it is long time since i posted…

Was just trying to see how a XML can be converted to JSON and to HashMap.

The situation is very imaginary.

    import java.io.File;
    import java.io.FileInputStream;
    import java.io.IOException;
    import java.io.InputStream;
    import java.util.ArrayList;
    import java.util.List;
    import java.util.Map;

    import net.sf.json.JSON;
    import net.sf.json.xml.XMLSerializer;

    import org.apache.commons.io.IOUtils;
    import org.codehaus.jackson.JsonGenerationException;
    import org.codehaus.jackson.map.JsonMappingException;
    import org.codehaus.jackson.map.ObjectMapper;
    import org.codehaus.jackson.type.TypeReference;

    public class XML2JSONConvertor {
    public static void main(String[] args) throws Exception {

    InputStream is = new FileInputStream(new File(
    “e:\\jagannathan\\personal\\java-projects\\secondtest.xml”));
    String xml = IOUtils.toString(is);

    XMLSerializer xmlSerializer = new XMLSerializer();
    JSON json = xmlSerializer.read(xml);

    System.out.println(json.toString(2));

    printJSON(json.toString(2));

    }

    public static void printJSON(String jsonString) {
    ObjectMapper mapper = new ObjectMapper();

    try {

    Map<String, Object> jsonInMap = mapper.readValue(jsonString,
    new TypeReference<Map<String, Object>>() {
    });

    List<String> keys = new ArrayList<String>(jsonInMap.keySet());

    for (String key : keys) {
    System.out.println(key + “: ” + jsonInMap.get(key));
    }

    } catch (JsonGenerationException e) {
    e.printStackTrace();
    } catch (JsonMappingException e) {
    e.printStackTrace();
    } catch (IOException e) {
    e.printStackTrace();
    }
    }
    }

The Input XML

<?xml version=”1.0″ encoding=”UTF-8″?>
<company>
<name>Jags Inc</name>
<employees>
<employee>
<name>Jagan</name>
<sex>Male</sex>
<dob>24-jul</dob>
</employee>
<employee>
<name>Satya</name>
<sex>Male</sex>
<dob>24-apr</dob>
</employee>
</employees>
</company>

The output

7 Feb, 2013 7:20:50 PM net.sf.json.xml.XMLSerializer getType
INFO: Using default type string
{
“name”: “Jags Inc”,
“employees”: [
{
"name": "Jagan",
"sex": "Male",
"dob": "24-jul"
},
{
"name": "Satya",
"sex": "Male",
"dob": "24-apr"
}
]
}
name: Jags Inc
employees: [{name=Jagan, sex=Male, dob=24-jul}, {name=Satya, sex=Male, dob=24-apr}]
