The document describes how to use the json-to-xml-transformer in Mule to transform JSON input to XML output. It provides a JSON sample input and the corresponding XML output, and shows the flow configuration using the json-to-xml transformer to listen on port 8081 and transform the JSON payload to XML.

1. HOWTOTRANSFORM JSONTO XML IN
MULE

2. We have to use the json-to-xml-transformer to transform a json
message to xml.
I don't need any transformation of the data,
simply turning the json properties into xml tags.

3. {
"root": {
"name": “Mike",
"fullname": “Muller",
"address": “55 seventh street",
"shipToZip": "16684",
JSON Input :

4. "lineInfo": [
{
"lineNumber": “523",
"product": “FAT999"
}
]
}
}

5. Output:
<?xml version='1.0'?>
<root>
<name>Mike</name>
<fullname>Muller</fullname>
<address> 55 seventh street</address>
<shipToZip>16684</shipToZip>
<lineInfo>
<lineNumber>523</lineNumber>
<product>FAT999</product>
</lineInfo>
</root>
