Transformation xmltoobjectesb
- 1. XML to Object transformation in Mule with Dataweave
- 2. As we know, there can be multiple types of payload we need to deal daily, starting from JSON, XML or String, we also require different type of data transformation in our application like XML to JSON, JSON to XML or String etc . In Mule application, we have a various set of transformers that we can use to obtain our required data format.
- 3. Today we will be discussing on transformation of XML to Object format of data. So, let us consider, we have the following XML payload as an input to our application < user> <name>John</name> <lastName>Rich</lastName> </user>

- 10. In the transform code I created the Object type in the header “ %type user = :object { class: "testdatajava.User"} ” And the payload of the transform is converted to User Object using the transform logic as below. { firstName: payload.user.name, lastName: payload.user.lastName } as :user Transformer
- 11. User.java public class User { private String firstName; private String lastName; public String getFirstName() { return firstName; } public void setFirstName(String firstName) { this.firstName = firstName; }
- 12. public String getLastName() { return lastName; } public void setLastName(String lastName) { this.lastName = lastName; } @Override public String toString() { // TODO Auto-generated method stub return this.firstName + " " + this.lastName; } }
