Thanks! | You can effectively invert your regular expression using a [negative look-ahead](http://www.regular-expressions.info/lookaround.html).
For example, consider the following regular expression that matches only a string of digits:
```
^\d+$
```
This expression could be inverted as follows:
```
^(?!\d+$).*$
