Having trouble with regular expression, please help

[jx05 0]

Hi, I am new to regular expression, but in Ubot 4, I was trying to process a piece of text, for example:

 

The sky (is blue, leaves are green) and the (wind) is blowing

 

I want to replace all texts in the brackets with something like ***, so the new text will look like this:

 

The sky *** and the *** is blowing

 

I use replace regular expression, and the regular expression is \(.*\), however, the result is:

 

The sky *** is blowing

 

apparently, the regular expression only recognize the very first opening bracket ( and the very last closing bracket ), everything between them are replaced with ***.

 

What regular expression should I use to correct the mistake? I am totally confused, any help would be appreciated!
