In the previous post, we have seen parsing JSON value using User Defined Function..

Let’s check how to parse XML using User Defined Function.

Example

  • Use parseXML function as a Groovy function to parse an XML and store the values in an object.
  • The object returned from the parseXML is a JsonNode. (from JsonNode (jackson-databind 2.7.0 API))
  • Use any of the methods in the above docs on the object to extract or manipulate the JSON before returning it.
  • parseStudentXML function below parses the student data in an XML format.
type Query {
    parseStudentXML(value: String): Json  @tan(type:Groovy, inline: """return parseXML(value)""")
}

Let’s execute the function!

{
  parseStudentXML(
    value: "<student><name>Hypi</name><platform>low code</platform><url>https://hypi.io/</url><body>Build App</body></student>"
  )
}
#result
{
  "data": {
    "parseStudentXML": {
      "name": "Hypi",
      "platform": "low code",
      "url": "https://hypi.io/",
      "body": "Build App"
    }
  }
}
