<?xml version="1.0" encoding="utf-8"?>
<MyBeerJournal>
    <Brewery name="Founders Brewing Company" location="Grand Rapids, MI">
        <Beer name="Centennial" description="IPA" rating="A+" dateSampled="01/02/2011">

I have some example to increase this post. My example is based on creation of scene referential with hierarchy.
XML file :

<?xml version="1.0" encoding="utf-8"?>
<WORLD>
    <REF name="LocalRef_1">
        <REF name="LocalRef_1_1">
            <REF name="LocalRef_1_1_1">
            </REF>
            <REF name="LocalRef_1_1_2">
            </REF>
            <REF name="LocalRef_1_1_3">
            </REF>
        </REF>
    </REF>
</WORLD>

My code to browse information :

 for (rapidxml::xml_node<>* node = doc.first_node("WORLD")->first_node("REF"); node != nullptr; node = node->first_node())
{
	cout << "A : " << node->first_attribute("name")->value() << endl;
        for (rapidxml::xml_node<>* node2 = node; node2 != nullptr; node2 = node2->next_sibling())
        {
	        cout << "B : " << node2->first_attribute("name")->value() <<endl;
        }
}

My result:

A : LocalRef_1
B : LocalRef_1
A : LocalRef_1_1
B : LocalRef_1_1
A : LocalRef_1_1_1
B : LocalRef_1_1_1
B : LocalRef_1_1_2
B : LocalRef_1_1_3

Have fun ! :)

Excellent example.
Thank you.
