boost :: archive :: xml_iarchive失败，带有一个xml（deserizalisation上下文）

（我在windows下并使用visual studio 2015.）我收到xml放在问题的末尾，以单行格式，但我漂亮印刷（XML只有换行符）与notepad++为便利。boost :: archive :: xml_iarchive失败，带有一个xml（deserizalisation上下文）

std::ifstream file("D:\\FILES\\anxmlfile.xml"); 
char msg[500]; 
strerror_s(msg,errno); 
try 
{ 
    boost::archive::xml_iarchive ia(file); 
    interestRateCurve IRCurve; 
    ia >> BOOST_SERIALIZATION_NVP(IRCurve); 
} 
catch (boost::archive::archive_exception ex) 
{ 
    // blah 
}

其中msg收到 “没有错误”，并在那里

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

触发boost::archive::archive_exception与{m_buffer=0x00e8f504 "unrecognized XML syntax" code=other_exception }。该interestRateCurve类被定义为如下：

#pragma once 

#include <string>

#include "boost/archive/text_iarchive.hpp"

以下简短的XML（具有升压代码段产生）不会触发相同的错误：

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

我在做什么错？格式真的是错误的，为什么？如果不是，该怎么办？

我的XML的

解决了这个问题，但当然不是我一个可行的解决方案，因为我有几百万相同形式的XML的比我“M与战斗...

问题是Boost没有XML库。

您似乎认为Boost Serialization可以读取XML。实际上，它只能读取XML文档的一个子集，即Boost Serialization Archives，它是一种特定的格式。如果您没有这种格式，则无法使用Boost Serialization来读取它。

相反，只需使用XML库。我建议PugiXML或libxml2的：

What XML parser should I use in C++?

哦，好吧，的确没有知道升压序列化只能读取XML文档的子集，THX！ PugiXML我试过了，确实没问题，但是没有使用预编译头文件，这是我运行的大解决方案中的一个问题。我将给libxml2一个镜头：我可以在windows下使用mvs？你怎么看待http://stackoverflow.com/questions/28037909/xml-parsing-using-boost？我知道，它本身并不是反序列化...... –

呵呵。如果您使用预编译头文件，PugiXML可以正常工作。另外，除非你不知道如何避免紧密耦合，否则永远不会出现“大型解决方案”中的问题。基本上，确保您永远不要将XML库标头包含在“公共”或共享标头文件中。只将它包含在使用它的（一）cpp中。 – sehe

我喜欢你链接的答案:)它说完全一样。如果您需要PugiXML的帮助，请查看[使用它的一些示例]（https://stackoverflow.com/search?tab=votes&q=user%3a85371%20pugixml）。 Libxml2将会更难以在MSVC下设置 – sehe

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 
}

的伎俩，但随后

ia >> BOOST_SERIALIZATION_NVP(IRCurve);

触发“”输入流错误“code = input_stream_error”。我不知道是否这是因为interestRateCurve类的设计不好，因此无法完成这项工作，或者如果我的答案根本不是正确的答案，导致“坏”bst::archive::xml_iarchive？（bst::archive::xml_iarchive在调试时看起来很正常。）
