Question

I need to parse Windows text file and extract all data related to operations. Operations
are separated with $OPERATION and $OPERATION_END. What I need to do is extract all text blocks for all operations. How can I do it effectively
using regex or simple String methods. I would appreciate you provide small snippet.

$OPERS_LIST
//some general data

$OPERATION
//some text block
$OPERATION_END


$OPERS_LIST_END

Answer 1

to get all operations from the list:

var input = @"$OPERS_LIST
//some general data

$OPERATION

erfgergwerg
ewrg//some text block

$OPERATION_END

$OPERATION
//some text block
$OPERATION_END


$OPERATION
//some text block
$OPERATION_END


$OPERS_LIST_END";
foreach (Match match in Regex.Matches(input, @"(?s)\$OPERATION(?<op>.+?)\$OPERATION_END"))
{
 var operation = match.Groups["op"].Value;

 // do something with operation...
}
