Extract outline of current appearance

[Betsey378470312m4p]

Hi!  I have some shapes cover over others with its white color. I want to maintain this appearance and extract its outline only. How can I do this? 

[ ↓ I want to extract the outline like this without fill but maintain the current appearance and the layering of the current white shape fills.]

[↓There are layering shapes underneath... I don't want the below shapes pop up on the extraction]
