If 

doc_p.parse ("hello.xml");

treats its argument as a file name, what do you think this call will
treat it as?

std::string s;
...
doc_p.parse (s);

I think it is pretty clear it will still treat it as a file name
(no, calling it 'contents' doesn't help).

If you want to parse a chunk of memory, you can do something like
this:

std::string s;
...
doc_p.parse (s.c_str (), s.size (), true);

See documentation for more information.
