Trying to convert any type of XML file to JSON object structure . Different xml files are having varied depths of elements and sub-elements. creation of arrays when elements with same name are at same height I need a recursive function which create exact JSON Object for any structured XML file

Did you tried???? use XML.toJSONObject() method of org.json.Shivam– Shivam2015-10-30 14:10:14 +00:00Commented Oct 30, 2015 at 14:10

You can call this method recursively. Just try and if there is any problem then post Question with the code next time.Shivam– Shivam2015-10-30 14:22:47 +00:00Commented Oct 30, 2015 at 14:22

Please refer to Jackson Mapper
XmlMapper xmlMapper = new XmlMapper();
String xml= FileUtils.readFileToString(new File("test_4.xsd.xml"),Charset.defaultCharset());
JsonNode node = xmlMapper.readTree(xml.getBytes());
ObjectMapper jsonMapper = new ObjectMapper();
String json = jsonMapper.writeValueAsString(node);
System.out.println(json);
