How about gSOAP? It is open source and freely available under the GPL license. Despite its name, the gSOAP toolkit is a generic XML data binding tool and allows you to bind your C and C++ data to XML automatically. There is no need to use an XML parser API, just let it read/write your data in XML format for you. If you really need a super-simple C++ XML parser then gSOAP may be an overkill. But for everything else it has worked well as testimonials show for many industrial applications since gSOAP was introduced in 2001.

下面是一个简单的功能列表:

Portable: Windows, Linux, Mac OS X, Unix, VxWorks, Symbian, Palm OS, WinCE, etc. Small footprint: 73KB code and less than 2K data to implement an XML web service client app (no DOM to limit memory usage). Fast: do not believe what other tools claim, the true speed should be measured with I/O. For gSOAP it is over 3000 roundtrip XML messages over TCP/IP. XML parsing overhead is negligible as it is a simple linear scan of the input/output while (de)serialization takes place. XML support: XML schema (XSD) import/export, WSDL import/export, XML namespaces, XML canonicalization, XML with attachments (MIME), optional use of DOM, many options to produce XML with indentation, use UTF8 strings, etc. XML validation: partial and full (option) WS support: WS-Security, WS-ReliableMessaging, WS-Addressing, WS-Policy, WS-SecurityPolicy, and other. Debugging: integrated memory management with leak detection, logging. API: no API to learn, only "soap" engine context initialization, then use the read/write interface for your data, and "soap" engine context destruction.

例如:

class Address
{ 
  std::string name;
  std::vector<LONG64> number;
  time_t date;
};

然后在上面的Address类声明上运行"soapcpp2"来生成soap_read_Address和soap_write_Address XML读取器和写入器，例如:

Address *a = new Address();
a = ...;
soap ctx = soap_new();
soap_write_Address(ctx, a);
soap_end(ctx);
soap_free(ctx);`

这将生成Address a对象的XML表示形式。通过用XML名称空间细节注释头文件声明(这里没有显示)，这些工具还生成模式。这是一个简单的例子。gSOAP工具可以处理非常广泛的C和c++数据类型，包括基于指针的链接结构，甚至(循环)图(而不仅仅是树)。

希望这能有所帮助。

我喜欢Gnome xml解析器。它是开源的(MIT许可，所以你可以在商业产品中使用它)，速度快，并且有基于DOM和SAX的接口。

TinyXML试试。

我是一个c++新手，在尝试了这个页面上的几个不同的建议后，我必须说我最喜欢pugixml。它有易于理解的文档和高层次的API，这是我一直在寻找的。

TinyXML，还有boost。propertytree。后者并不满足所有的官方要求，但非常简单。

如果你关心效率/内存管理，不要使用TinyXML(它倾向于分配大量的小块)。我个人最喜欢的是RapidXML。
