XML文件中的C＃dataGridView

Question

I know there are lots of resources that show how to bind dataGridViews to XML files or populate from XML, but the XML i'm using as source is a bit more complex than any example I've seen used and I'm struggling. (although it really shouldn't be difficult)

I basically need to run several queries (I think) to get the data I want to populate the DGV, because the elements I want the content from are on different parent nodes of the XML.

Here is what I have, and the comments should show you what I'm trying to achieve:

XDocument xmlDoc = XDocument.Load("Techdocx_dml.xml");
                var q = from c in xmlDoc.Root.Descendants("dmentry")
                             .Descendants("avee")
                            //.Descendants("dmtitle") I also need to access this descendant
                    select new
                    {
                        modelic = c.Element("modelic").Value,
                        sdc = c.Element("sdc").Value,
                        chapnum = c.Element("chapnum").Value,
                        section = c.Element("section").Value,
                        subsect = c.Element("subsect").Value,
                        subject = c.Element("subject").Value,
                        discode = c.Element("discode").Value,
                        discodev = c.Element("discodev").Value,
                        incode = c.Element("incode").Value,
                        incodev = c.Element("incodev").Value,
                        itemloc = c.Element("itemloc").Value,

                       // techname = c.Element("techname").Value, 
                       //need this value, which is on the "dmtitle" node, not the "avee" node


                    };



                dataGridView1.DataSource = q.ToList();
                dataGridView1.ColumnHeadersVisible = false;

                dataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCells;

This is what i want in my dataGridView:

AA A 32 3 5 00 01 A 018 A A | Some title 1 | Introduction 
AA A 32 3 5 00 01 A 920 A A | Some title 2 | Some infoname 2

How do I achieve this please? Example XML below:

Try this :

            DataTable dt = new DataTable();
            dt.Columns.Add("modelic", typeof(string));
            dt.Columns.Add("sdc", typeof(string));

            }

            dataGridView1.DataSource = dt;


        }
    }
