Xml to xml transformation in mule
- 1. XML to XML transformation in Mule
- 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 XML format of data. Yuo will realize how easy it is to perform such type of transformation in Mule. Here we will take the same example, but will be doing it on XML instead of JSON this time. So, let us consider, we have the following XML payload as an input to our application
- 4. <RootTag> <name>Walter White</name> <id>55</id> </RootTag> We can see here the XML contains only 2 elements, that is name and id.
- 5. So, now if this XML data is coming as an input and we require to transform/modify the payload into another XML format and produce it as an output, something like the following: <RootTag> <name>Walter White</name> <id>55</id> <designation>Manager</designation> </RootTag>
- 6. And here you can see the modified XML has a new element designation as a third element . Now, the challenge here is to modify the existing input XML payload and to design an output XML payload from it, which will contain this additional element in it with the same format. So, how can we transform/modify the payload into another XML format in an easy way. We know Mule has extremely powerful tools called Datamapper but that limited to Mule enterprise edition.
- 7. A simple way of doing it is using XSLT in Mule. Mule do have XSLT support in itās flow, which makes the life of a developer easy in transforming/modifying XML in the required format. So, here is the Mule flow which can be use to transform XML payload from one format to another using XSLT
