Deleting edges from SimpleWeightedDiGraph based on edge weight

Hi,

i would like to remove multiple edges from a SimpleWeightedDiGraph based on their weight.

However, naively looping over edges as in the example below does not yield the desired result, presumably because the internal ordering of the edges is changed when an edge is removed.

using LightGraphs, SimpleWeightedGraphs

g = SimpleWeightedDiGraph([1, 2, 3], [2, 3, 1], [1.0, 6.0, 4.0])
c = 5.0
for e in edges(g)
    if weight(e) < c 
        rem_edge!(g, e) 
    end
 end

julia> ne(g)
3

Does anyone have an efficient solution for this?

Best
Jakob
