How to get all sets of response time from user to agent in the entire log

[rajaguru2790]

In the above log

User(Saj) to Agent(Rohi) Response for all the conversations in the log should be captured: In the above example three valid user to agent response is there.If there are multiple Agent's response in between it can be ignored.Only the user response should be captured and after that next agent immediate response should be captured parsing the entire log.

1st set: Difference from user to agent time needed in Secs:
User Response: 1/1/2019 2:42:55 AM
Agent Response: 1/1/2019 2:51:16 AM (Initial Response Found already using Regex)

2nd Set: Difference from user time to agent time is needed
User Response: 1/1/2019 2:54:38 AM
Agent Response: 1/1/2019 2:55:12 AM

3rd Set: Difference from user time to agent time is needed
User Response: 1/1/2019 2:56:39 AM
Agent Response: 1/1/2019 2:57:10 AM

Like this if "n" number of sets are there everything should be displayed and their
Interaction Measurement Number (Sequential Number starting at 1 to N that identifies the unique measurement in the session log extracted by sequentially parsing the Chat Session log)
Response Start Time - Time associated with User part of the User  Agent interaction number measurement from the Session log
Response End Time – Time associated with the Agent part of the User  Agent interaction number measurement from the Session log
Agent Interaction Response Time – Difference in End Time and Start Time of the interaction number measurement for the interaction number.
