BOOST :: Archive :: XML_IARCHIVE带有XML(Deserizalisation Conte
boost::archive::xml_iarchive fails with an xml (deserizalisation context)
(我在Windows下方，使用VisualStudio2015。(我以一行格式收到XML放置的XML，但我非常印刷(仅XML仅带有线路断路的XML(使用notepad++进行偶然。
std::ifstream file("D:\FILES\anxmlfile.xml");
char msg[500];
strerror_s(msg,errno);
try

boost::archive::xml_iarchive ia(file);

ia >> BOOST_SERIALIZATION_NVP(IRCurve);
}
catch (boost::archive::archive_exception ex)
{
// blah
}
msg收到"无错误"的地方
boost::archive::xml_iarchive ia(file);
使用{m_buffer=0x00e8f504 "unrecognized XML syntax" code=other_exception }触发boost::archive::archive_exception。兴趣类别类的定义如下：

以下简短XML(使用Boost代码段生产(不会触发相同的错误：

解决了这个问题，但是当然对我来说不是一个可行的解决方案，因为我拥有数百万XML相同的形式，而不是我与...
问题是boost没有XML库。
您似乎认为增强序列化可以读取XML。实际上，它只能读取XML文档的子集，即促进序列化档案，这是一种特定格式。如果您没有这种格式，则不能使用Boost Serialization读取它。
相反，只需使用XML库即可。我建议pugixml或libxml2：
我应该在C ？
std::ifstream file("D:\FILES\anxmlfile.xml");
char msg[500];
strerror_s(msg,errno);
try
{
unsigned int flags = boost::archive::no_header;
boost::archive::xml_iarchive ia(file, flags);
interestRateCurve IRCurve;
ia >> BOOST_SERIALIZATION_NVP(IRCurve);
}
catch (boost::archive::archive_exception ex)
{
// blah
}
做这个问题，但是
ia >> BOOST_SERIALIZATION_NVP(IRCurve);
触发一个"输入流错误"代码= input_stream_error"。我不知道这是否是因为兴趣级别的设计不好，因此无法完成这项工作，或者我的答案根本不是正确的答案，从而导致"不良" bst::archive::xml_iarchive？( bst::archive::xml_iarchive在调试中看起来很正常。(
