<root>
    <level1 name="A">
        <level2 name="A1" />
        <level2 name="A2" />
    </level1>
    <level1 name="B">

//Load xml
XDocument xdoc = XDocument.Load("data.xml");

//Run query
var lv1s = from lv1 in xdoc.Descendants("level1")
           select new { 
               Header = lv1.Attribute("name").Value,
               Children = lv1.Descendants("level2")
           };

//Loop through results
foreach (var lv1 in lv1s){
        result.AppendLine(lv1.Header);
        foreach(var lv2 in lv1.Children)
             result.AppendLine("     " + lv2.Attribute("name").Value);
