- [x] Example task. | Task ends. [x] Another task.
- [x] ! Example task. | This ends. [x] ! Another task.
This is a sentence. [x] Task is here.
Other text. Another [x] ! Task is here.
Must not match in the table.
| | Task name | Plan | Actual | File |
| :---- | :-------------| :---------: | :---------: | :------------: |
| [x] | Task example. | 08:00-08:45 | 08:00-09:00 | [[task-one]] |
| [x] ! | Task example. | 08:00-08:45 | 08:00-09:00 | [[task-one]] |
Groups expected:
$1: all text after [x]
$2: all text after [x] !
Regex for each group:
$1: [^|\s]\s*\[x\](?!\s*!)\s*\K[^!|\n]*
$2: [^|\s]\s*\[x\]\s*!\s*\K[^|\n]*
With the not-capturing group applied:
$1: (?:[^|\s]\s*\[x\](?!\s*!)\s*\K([^!|\n]*))
$2: (?:[^|\s]\s*\[x\]\s*!\s*\K([^|\n]*))
The combined expression:
(?:[^|\s]\s*\[x\](?!\s*!)\s*\K([^!|\n]*))|(?:[^|\s]\s*\[x\]\s*!\s*\K([^|\n]*))`
for i, match := range re.FindAllString(str, -1) {
