XML parsing using java

There is another similar question.

I personally used XOM and liked it.

Use the DOM, like shown here: http://www.java-samples.com/showtutorial.php?tutorialid=152 for example.

Since its a soap response, why don't you write a nice simple web service client to retrieve the response and automatically turn it into objects for you.

There's an example of that here.

You can use DSM stream parsing library to convert key-value pair to List then get what you want.

This is the first approach. To do this you should define your yaml mapping file as follows.

result:
  type: array     # result is array
  path: /.+item   # read item tag. the path is a regex.
  fields:
    key:
    value:

Java Code to parse XML:

DSM dsm=new DSMBuilder(new File("path/to/mapping.yaml")).setType(DSMBuilder.TYPE.XML).create();
List<Map<String, Object>> itemList =  (List<Map<String, Object>>)dsm.toObject(xmlFileContent);

Here is itemList list that converted to json.

[ {
  "key" : "Application",
  "value" : "MobileDevice"
}, {
  "key" : "Version",
  "value" : "1.0"
}, {
  "key" : "Username",
  "value" : "ramau"
}, {
  "key" : "token",
  "value" : null
}, {
  "key" : "sessionID",
  "value" : "SESSIONID"
}, {
  "key" : "OSInformation",
  "value" : "windowsXP"
} ]

The second approach is converting XML to a java map that it's key of map is value of key tag and value of the map is the value of the value tag in XML.

Here is Mapping File:

result:
  type: object     # result is map
  path: /.+multiRef # path is regex
  fields:
    key:
      path: item/key # read value of /.+multiRef/item/key tag
    value:
      path: item/value # read value of /.+multiRef/item/value tag
    application:
      parentPath: item  # assign default value when /.+multiRef/item tag is closed
      default: $self.data.value  # get value of value field.
      filter: $self.data.key=='Application' # assign if key filed is 'Application'
    version:
      parentPath: item
      default: $self.data.value
      filter: $self.data.key=='Version'
    username:
      parentPath: item
      default: $self.data.value
      filter: $self.data.key=='Username'
    token:
      parentPath: item
      default: $self.data.value
      filter: $self.data.key=='token'
    sessionID:
      parentPath: item
      default: $self.data.value
      filter: $self.data.key=='sessionID'
    OSInformation:
      parentPath: item
      default: $self.data.value
      filter: $self.data.key=='OSInformation'

Java Code to parse XML:

DSM dsm=new DSMBuilder(new File("path/to/mapping.yaml")).setType(DSMBuilder.TYPE.XML).create();
Map<String, Object> result =  (Map<String, Object>)dsm.toObject(xmlFileContent);

String application=result.get("application").toString()

Here is the JSON representation of Result:

{
  "key" : "OSInformation",
  "value" : "windowsXP",
  "application" : "MobileDevice",
  "version" : "1.0",
  "username" : "ramau",
  "token" : null,
  "sessionID" : "SESSIONID",
  "OSInformation" : "windowsXP"
}

In first it's come a bit complicated but if you look at docs it is very easy.
