How to extract text and set as variable Batch Code CMD

问题

I would like to extract what users are online based on this text file:
https://minecraft-statistic.net/en/server/167.114.43.185_25565/json/

I will save it as a text file. Inside that there is something:

"players_list":["Raskhol"]["Lukaka"],"map":...etc

I would like to extract all the text between "_list": and ,"map" and set it as a variable. So that when I call the variable %Playerlist%, it would say:

["Raskhol"]["Lukaka"]

回答1:

similar to @geisterfurz007's answer, this one assumes the you are after the first instance of "players_list": before the first instance of ,"map"

@Echo Off
Set/P var=<some.json
Set var=%var:,"map"=&:%
Set var=%var:*"players_list":=%
Echo=%var%
Timeout -1

Not tested due to beeing on phone.

@echo off
For /f "delims=: tokens=2" %%g in (PathTo\file.txt) do (
Set var=%%g
Goto:next
)
:next
Set var=%var:,map=%
echo %var%

Assumes players are the first to be listed.

Reads the file, takes the part after the first : up to the second one, stores it in var.
Then ,map gets replaces with nothing to result in just the players beeing echoed in the end.

Feel free to ask questions if something is unclear! Might take a while as I am currently mobile though.
