Description:
- $1:
- outside the table: capture everything after \`[x]\` (i.e., not followed by \`!\`) until a \`|\`
- inside the table: capture everything after \`[x]\` (i.e., not followed by \`!\`) excluding the \`|\` symbols
- $2:
- outside the table: capture everything after \`[x] !\` until a \`|\`
- inside the table: capture everything after \`[x] !\` excluding the \`|\` symbols
Expressions for each group:
- $1:
- outside the table: [^\|\s]\s*\[x\]\s*\K[^!|\n]*
- inside the table: (?:\G(?!\A)\||(?<=\[x]\s)\s*\|)\K[^|\n]*(?=\|)
- $2:
- outside the table: [^\|\s]\s*\[x\]\s*\!\s*\K[^|\n]*
- inside the table: (?:\G(?!\A)\||(?<=\[x]\s)\s*\!\s*\|)\K[^|\n]*(?=\|)
Combined expression:
([^\|\s]\s*\[x\]\s*\K[^!|\n]*|(?:\G(?!\A)\||(?<=\[x]\s)\s*\|)\K[^|\n]*(?=\|))|([^\|\s]\s*\[x\]\s*\!\s*\K[^|\n]*|(?:\G(?!\A)\||(?<=\[x]\s)\s*\!\s*\|)\K[^|\n]*(?=\|))
