        print(back_inserter(xmlstring), doc);

Apart from the necessary #includes, and missing using namespace rapidxml; your code compiles and runs fine for me.

xmlstring contains this:

<?xml version="1.0" encoding="utf-8"?>
<root ="">
    <old/>
    <boy/>
</root>

Because old and boy have no content, they use xml empty element tags, <tagname/>rather than start and end pairs like <tagname></tagname>
