Hi
In the text file below, I want to obtain everything between "|[" and "]|".
system
component1 |[ b,a,d, w,e,r ]| component2
endsystem
so the output is : b,a,d, w,e,r
Thanks in advance.

Please refer to the functions fileread & regexp.
Let's assume that the following content
"system
component1 |[ b,a,d, w,e,r ]| component2
endsystem"
is in a text file named textFile.txt then the following code might help you:
textChar = fileread("textFile.txt");
startIndex = regexp(textChar,'|[');
endIndex = regexp(textChar,']|');
requiredOutput = textChar(startIndex+1:endIndex-2)
