To be correct, the delta "function" is a (irregular) distribution (not a function), so from the physical point of view it only makes sense to talk about it when integrating over it. You can imagine it as a the limit of a Gaussian, where the width approaches zero while the integral stays constant. (Hence the height gets infinity.) If it's (delta(xx')) together with any other function f(x) inside of an integral, the integral just leads to the value of the function at the point x=x', i.e. f(x'). Don't know if this really helps, but in principle I would say it's more like a mathematical trick (or property) then a physical interpretation of it.
