Re: Compiler Errors

xmlpp::Document::write_to_file() or 
xmlpp::Document::write_to_file_formatted(). Don't expect too much from 
write_to_file_formatted(). It won't format exactly as you would like.
If you've created the xmlpp::Document with xmlpp::DomParser, you must 
first use xmlpp::DomParser::get_document().
This will write the whole document, not just the added nodes. I don't 
think there's an easy way to write just some selected nodes.

Have you read the documentation? Look e.g. at 
http://developer.gnome.org/libxml++/stable/.
