<![CDATA[How to replace - [X] *]]>Markdown checkbox
Mine:

// s is a string line.
if (s.startsWith("- [ ] "))
    s.replace("- [ ] ", "<input type=\"checkbox\">");

if (s.startsWith("- [x] "))
    s.replace("- [x] ", "<input type=\"checkbox\" checked>");

if (s.startsWith("- [X] "))
    s.replace("- [X] ", "<input type=\"checkbox\" checked>");

Target:

// * means strings, add \n at line end
if (s.startsWith("- [ ] "))
    s.replace("- [ ] *", "<input type=\"checkbox\">*\n");

if (s.startsWith("- [x] "))
    s.replace("- [x] *", "<input type=\"checkbox\" checked>*\n");

if (s.startsWith("- [X] "))
    s.replace("- [X] *", "<input type=\"checkbox\" checked>*\n");

We could do this in a couple of ways:

if (s.startsWith("- [ ] ")) {
    s.replace("- [ ] ", "<input type=\"checkbox\">");
    s.append("\n");
}

or

s.replace(QRegularExpression("^- \\[ \\] (.*)$"), "<input type=\"checkbox\">\\1\n");

However, I suspect putting in a \n newline will not do what you want. Per your other post and the linked picture there I think you want these "items" on separate lines. Remember that in HTML \n is just the same as any other whitespace character so it will just producer a space and stay on same line. You probably want either to insert a line break, HTML <br>, or possibly put your items into some kind of HTML list (like <dl> <dt>).
