Sample call:
The following JSON document is to be loaded into the DOM memory:
sMessage := '{"serialNumber":"123","batteryVoltage":"1547mV","clickType":"SINGLE", "array":["Hello",2,3]}';
The "array" property is to be deleted. First of all, the JSON document is searched for the "array" property, after which the property is removed.
jsonDoc := fbJson.ParseDocument(sMessage);
jsonIterator := fbJson.MemberBegin(jsonDoc);
jsonIteratorEnd := fbJson.MemberEnd(jsonDoc);
WHILE jsonIterator <> jsonIteratorEnd DO
sName := fbJson.GetMemberName(jsonIterator);
IF sName = 'array' THEN
fbJson.RemoveMember(jsonDoc, jsonIterator);
END_IF
jsonIterator := fbJson.NextMember(jsonIterator);
