Answer 1

This is a bit fixed but would work

var sb = new StringBuilder();
var root = XElement.Parse(xml);

sb.Append(root.Elements("Book").Attributes("Genre").Value);
sb.Append("+");
sb.Append(root.Elements("Book").Attributes("Style").Value);
sb.Append("+");
sb.Append(root.Elements("Book").Elements("author").Attributes("id").Value);

etc...

You could also try LinqToXml. I've put together a quick example which would work for a case where you had multiple books within your bookstore root element:

XDocument doc = XDocument.Load(@"c:\\temp\test.xml");
        var query = from c in doc.Descendants("Book")
                    select c;

        foreach(XElement xe in query)
        {
            Console.WriteLine(xe.Name + "+" + xe.Attribute("Genre").Value + "+" + xe.Attribute("Style").Value);
            Console.WriteLine(xe.Element("author").Attribute("id").Value);
//etc etc etc
        }

Obviously, the Console.WriteLine statements would be replaced with StringBuilder.Append statements in your final solution!
