[Boost-users] Problem with Graphviz (read) and subgraphs

Can you help me writing a simple function that iterates on all subgraphs in the .dot file and print out the
1. subgraph name
2. for each edge source label / edge label / target label
?

I've tryed with this but didn't work:

[...]
boost::GraphvizDigraph g;
boost::read_graphviz(efsmfile, g);
[...]
    boost::GraphvizDigraph::children_iterator subgraph_index, subgraph_end;
    for (boost::tie(subgraph_index, subgraph_end) = g.children(); subgraph_index != subgraph_end; subgraph_index++) {
      cout << get_graph_name(*subgraph_index) << endl;
    }

const string& EFSM::get_graph_name(const Graph& g) {
    const typename boost::graph_property<Graph, boost::graph_name_t>::type& name = boost::get_property(g, boost::graph_name);
    return name;
}
