Answer 1

The XML document must have one and only one root element. You have to add root element. For instance,

<?xml version="1.0" encoding="utf-8" ?> 
<Employees>
    <Employee>
       .....
    </Employee>
    <Employee>
       ....
    </Employee>
</Employees>

Answer 2

Assuming what you want to do is open the document anyway, you can set the ConformanceLevel of the XmlReader to ConformanceLevel.Fragment.

XmlReaderSettings settings = new XmlReaderSettings();
settings.ConformanceLevel = ConformanceLevel.Fragment;

// input is a stream or filename
using (XmlReader reader = XmlReader.Create(input, settings)) {
    // use the reader
}
