sql Query to replace the square bracket and the whole text inside with a single charecter

Hi All,

I  have a question.

I am using Sql Server 2012.

I have a  situation where i need to replace the entire text and the square bracket with a single charecter.

Eg:-> 

I have atext    san[123456dd]text

i just wanted to replace all teh text inside the sqaure bracket to another charecter say 'X' 

My end result should be sanXtext.

Could anyone help me regarding this?
