in the sample text, I need to match things in parentheses so \(.*?\)
but I only want things in parentheses that have an ending parentheses with four numbers at the end

\(.*?\) matches:
(see Figure 32.5)
(Fakhoury et al., 1999)
(Lawn et al., 2003)

but I need something that only matches:
(Fakhoury et al., 1999)
(Lawn et al., 2003)

I tried \(.*?\d\d\d\d\) but it is matching:
(see Figure 32.5). The brain FDG-PET frequently shows uptake of FDG in the medial temporal lobes, even when the MRI is normal (Fakhoury et al., 1999)

I need to somehow check for another opening parentheses in the .*? and not match if it finds one but I don't know how to do that within the reg ex

thank you

 

You should not use .* try something like a-z|A-Z|\- ,etc .
