Boost Graph read_graphml＆amp;动态顶点属性

Question

我使用了boost图库，并从graphml中读取图表：

<?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>

我有以下C ++函数：

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?
}

如何提取每个节点的id，resp。关联boost vertex_index和“id”-graphml-tag？

或者，如何识别我的boost图形结构中的顶点或将其映射到GraphML文件中的顶点？
