对于xml:

<?xml version="1.0" ?>

我尝试使用Boost进行如下解析：

int main ( int, char ** )
try
{
        // Will hold file contents.
    stringstream contents;
        // Open the file for the shortest time possible.
    { ifstream file("./SCB_nmap_tcp_traceroute.xml", ios::binary);
            // Make sure we have something to read.
        if ( !file.is_open() ) {
            throw ("Could not open file.");
        }
            // Copy contents "as efficiently as possible".
        contents << file.rdbuf();
    }
        // Do something "useful" with the file contents.
    cout << contents.rdbuf();
    using boost::property_tree::ptree;
    ptree pt;
    read_xml(contents, pt);
        BOOST_FOREACH(ptree::value_type &v, pt.get_child("runstats"))
                cout<<"Found trace"<<endl;

我正在获取一个没有这样的节点，通过BOOST_FOREACH为"nmaprun"、"trace"answers"runstats"转储核心。请提供建议。

在引发'boost:：exception_detail:：clone_inpl>'的实例后调用terminatewhat（）：没有这样的节点（runstats）中止（堆芯转储）

在您的定义中：

BOOST_FOREACH(ptree::value_type &v, pt.get_child("runstats"))

您需要将根节点放在runstats之前，请尝试：

BOOST_FOREACH(ptree::value_type &v, pt.get_child("nmaprun.runstats"))
