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 first array position is to be deleted. First of all, the JSON document is searched iteratively for the "array" property, after which the first element of the array is removed by calling the RemoveArray() method.
jsonDoc := fbJson.ParseDocument(sMessage);
jsonIterator := fbJson.MemberBegin(jsonDoc);
jsonIteratorEnd := fbJson.MemberEnd(jsonDoc);
WHILE jsonIterator <> jsonIteratorEnd DO
sName := fbJson.GetMemberName(jsonIterator);
jsonValue := fbJson.GetMemberValue(jsonIterator);
IF sName = 'array' THEN
jsonArrayIterator := fbJson.ArrayBegin(jsonValue);
fbJson.RemoveArray(jsonValue, jsonArrayIterator);
END_IF
jsonIterator := fbJson.NextMember(jsonIterator);
