Question:How to collect integrated terms in an expression

Hi, 

I have an expression F that has an addend which is a definite integral,-(int(del_u0(x)*(diff(N_xx(x), x)), x = 0 .. L)), and addends that are not, all the rest of them.

How can I create an expression that is the integrated addend only without the other ones?

In other words, how do i separate the integral term from the rest of them?

F := -(int(del_u0(x)*(diff(N_xx(x), x)), x = 0 .. L))+del_u0(L)*N_xx(L)-del_u0(0)*N_xx(0)+ibp2+ibp3

Thanks!

Shai
