Converting JSON to XML and Vice Versa
Let’s learn how to convert records between the JSON and XML formats.
We'll cover the following
We are going to produce a utility that converts records between the JSON and XML formats. The input is given as a command-line argument. The utility tries to guess the format of the input starting from XML. If xml.Unmarshal()
fails, then the utility tries using json.Unmarshal()
. If there is not a match, then the user is informed about the error condition. On the other hand, if xml.Unmarshal()
is successful, the data is stored in an XMLrec
variable and is then converted into a JSONrec
variable. The same happens with json.Unmarshal()
in the case where the xml.Unmarshal()
call is unsuccessful.
