+The `toJson` function is to convert the payload to JSon as a `String` value.
However if the payload is already a `String` then no conversion happens.
+So suppose the payload is a `Map` object as follows:

+Map<String, Object> map = new LinkedHashMap<>();
+map.put("name", "Jack");
+map.put("id", 123);

+There are also _pretty_ alternatives so when calling `toPrettyJson` will
output: TODO:

The `xpath` function is for working with XML and using XPath expressions to
extract data from XML payloads.
