MFC C++ and parse XML file, best way?

Question

Hello! What is the best way to read this in MFC C++?

What is the best way to write this in a XML file?

Like XDocument in C#

<ROOT>
	<SYSTEM lanes="2" isDispense="0" isPack="0"/>
	<MACHINE address="127.0.0.1" port="6000" identifier="33"/>
	<CLIENT port="7000" id="34"/>
	<CUSTOM  active="1" />
</ROOT>

Answer 1

With a little bit of fiddling around, Windows.Data.Xml is available. IIRC, this wraps MSXML, so that is always another option.

One important point to note, even though this is a WinRT component, this is usable in desktop applications without any major issue. To make it really easy, C++/WinRT can be used. There is one very important point to be made though, this can have some unintended consequences with MFC applications, and it often better to place this functionality in a separate DLL. First, C++/WinRT changes some settings to make MIDL capable of compiling WinRT IDL files, if your application is creating COM components then this will have an effect. Secondly, if anything is directly or indirectly including Windows.Globalization.h then this will cause compiler errors when included alongside the MFC headers. There are ways around it, but it is better to just separate the functionality.

I think that a good way is: to set the “Common Language Runtime Support” option to “.NET Framework Runtime Support (/clr)” in Project Properties (if possible), to add references to System.Xml and System.Xml.Linq assemblies, and to use the XmlDocument or XDocument classes like in C#.

Or to make parts of the code in the form of C# libraries.

Hi,

In addition to MSXML，

you can find popular XML libraries on GitHub.
Such as TinyXML, PugiXML
