Can't use XMLDocument - "incomplete type is not allowed"

Question

I am trying to parse XML content.
I want to use XMLDocument but when I use it like that:

XMLDocument doc; 

I receive an error:

incomplete type is not allowed

When I searched for this issue I found that some places write examples with these libraries:

#using <mscorlib.dll>
#using <System.dll>
#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
using namespace System::Xml::Schema;

But when I tried this I am received an error:

#using requires C++/CLI mode

What I need to do in order to be able to use XMLDocument object ?

If you look in the example source file xmltest.cpp you will see at the top:

using namespace tinyxml2;

So when you see code like:

int example_1()
{
    XMLDocument doc;
    doc.LoadFile( "resources/dream.xml" );

    return doc.ErrorID();
}

It is actually:

int example_1()
{
    tinyxml2::XMLDocument doc;
    doc.LoadFile( "resources/dream.xml" );

    return doc.ErrorID();
}

You must use the tinyxml2 namespace to identify the correct XMLDocument to use.

• When you add the source files to the project, right-click the cpp file and choose properties:

• Next, you need to tell it not to use precompiled headers:

Now you do not need the #include stdafx.h call.

As you can see, XMLDocument is also a Microsoft .NET Framework class:

Without the tinyxml2 namespace it will default to this .NET Framework class. That requires a compatible application which, for C++, would mean a C++/CLI project.
