Xpath in tExtractJsonFields giving incorrect output

[Anonymous]

Hello. I used Xpath for retrieving JsonFields as shown on the forum. However, the output is in the form of name-value pair which is not like the one shown on Talend Forum.
The output is as follows:-
.-------------+-----------+-----------------+------------------.
|                          tLogRow_1                           |
|=------------+-----------+-----------------+-----------------=|
|name         |id         |fname            |lname             |
|=------------+-----------+-----------------+-----------------=|
|{"name":"HR"}|{"id":"11"}|{"fname":"Ajay"} |{"lname":"Murthy"}|
|{"name":"HR"}|{"id":"11"}|{"fname":"Ameya"}|{"lname":"Pandey"}|
|{"name":"HR"}|{"id":"11"}|{"fname":"Amit"} |{"lname":"Joshi"} |


I want the output rows to contain a single value and not name-value pair as shown above. How can I achieve it (without using JsonPath) by using Xpath?

Hello! I got the desired output by deselecting the "Get Nodes" tab in tExtractJSONFields component. Since I am newbie to Talend, can anyone tell me the significance of "Get Nodes" tab?
