Yes, it's possible to use a regular expression to find the construction you described: SPACE + "." + any character + "."
Here's a regular expression that would match this pattern:
- Code: Select all Expand view
\s+\.\w\.
Let me break down this regex for you:
1. `\s+`: This matches one or more whitespace characters (including spaces, tabs, and newlines).
2. `\.`: This matches a literal dot (period). The backslash is used to escape the dot, as a dot normally has a special meaning in regex.
3. `\w`: This matches any word character (letters, digits, or underscore).
4. `\.`: Another literal dot.
This regex will find patterns like " .a.", " .B.", " .9.", etc. in your text.
