Mule xml parsing

This document discusses parsing an XML payload in Mule ESB using DataWeave. It provides an example XML input file with user data. It then shows a Mule flow configuration that uses a DataWeave transform to parse the XML payload and output it as a Java object with the first and last name values. The DataWeave code treats the XML payload like a static class in Java to retrieve the name and last name values from the XML tags and assign them to variables.

- 5. IN THE TRANSFORM CODE, JUST USE THE BELOW SIMPLE LOGIC. THE XML DATA WILL COME TO THE TRANSFORM MESSAGE AS PAYLOAD. NOW CONSIDER PAYLOAD AS A STATIC CLASS IN JAVA AND FOLLOW THE BELOW CODE TO GET THE WHATEVER THE DATA YOU NEED TO RETRIEVE FROM AN XML TAG. THE VALUES ARE ASSIGNED TO VARIABLES. { FIRSTNAME: PAYLOAD.USER.NAME, LASTNAME: PAYLOAD.USER.LASTNAME }
- 6. DATAWEAVE Test this service from a browser or by using the postman you can find the desired output
