Remove specific characters from a string in MySQL

Hi, 

I will like to know how I can remove some specific characters is a string. 
I have some strings of characters that contain this; [some_string this_id="1"]. I want to take out the number "1" name as "id_number" and remove the rest, [some_string this_id=""]. 

Is this possible in MySQL? 

Any help will be very appreciated. 

Thanks!
