[Boost-users] Retrieving edges list

I'm rather new with the use of the BGL, but I'd like to know how I could retrieve a weighted edges list from a graph, without forgetting vertices and weight, in a list for example, i.e. for n edges: Element 1 : egde 1; node 1’; node 1’’; weight 1 Element 2 : egde 2; node 2’; node 2’’; weight 2 ... Element n : egde n; node n’; node n’’; weight n Also, I’d like to know if I have different lists from different graphs, is there a mean to merge them into only one big list and to remove the unnecessary elements? Any suggestion welcome ;) NC
