Boost Graph read_graphml & dynamic vertex properties

问题

I have use the boost graph library and read in a graph from a graphml such as this:

<?xml version="1.0" encoding="UTF-8"?>
<graphml xmlns="http://graphml.graphdrawing.org/xmlns"  
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://graphml.graphdrawing.org/xmlns
   http://graphml.graphdrawing.org/xmlns/1.0/graphml.xsd">
    <graph id="G" edgedefault="directed">
        <node id="A"/>
        <node id="B"/>
        <edge id="0" source="A" target="B">
    </graph>
</graphml>

I have the following C++ function:

using namespace boost;
typedef adjacency_list<vecS, vecS, directedS> BoostGraphType;
typedef dynamic_properties BoostDynamicProperties;

BoostGraphType& g = ...;
BoostDynamicProperties& dp = ...;
read_graphml(is, g, dp);

// get the property map for vertex indices
typedef property_map<BoostGraphType, vertex_index_t>::type IndexMap;
IndexMap index_map = get(vertex_index, g);

typedef graph_traits<BoostGraphType>::vertex_iterator vertex_iter;
for (auto vp = vertices(g); vp.first != vp.second; ++vp.first)
{
    size_t index = index_map[*vp.first];
    // How do I get the id of the node?
}

How can I extract the id of each node, resp. associate the boost vertex_index and "id"-graphml-tag?

Alternatively, how can I identify or map the vertices in my boost graph structure to the vertices in my GraphML file?
