If the contents of the XML file is that basic as in your sample and the label is called Label1, you could manage with something like this:

XmlTextReader reader = new XmlTextReader(xmlFilePath);
while(reader.Read())
{
    if(reader.NodeType == XmlNodeType.Element && reader.Name == "foo")
    {
        reader.Read();
        Label1.Text = reader.Value;
    }
}
