Quick and dirty

            var xmlString = @"<Main>
                           <SubMain Name=""SubMain1"">
                            <Attribute1>Value1</Attribute1>
                            <Attribute2>Value2</Attribute2>
                            <Attributen>Valuen</Attributen>
                           </SubMain> 

                           <SubMain Name=""SubMain2"">
                            <Attribute1>Value1</Attribute1>
                            <Attribute2>Value2</Attribute2>
                            <Attributen>Valuen</Attributen>
                           </SubMain>
                          </Main>";

          var xDoc = XDocument.Parse(xmlString);
          var item = (from el in xDoc.Descendants("SubMain")
                      where el.Attribute("Name").Value == "SubMain2"
                      select el);
