I would like to parse this xml in to a datagridview table format like below
however, as you can see the code I'm currently using is not formatting it correctly -
int i = 0;
foreach(XmlNode node in doc.SelectNodes(query))
{
row = results.NewRow();
XmlNode Element = (XmlNode)node;
foreach (XmlNode node1 in Element)
{
XmlNode Element1 = (XmlNode)node1;
results.Columns.Add(Element1.Name, typeof(string)); //(Colour)
}
foreach (XmlNode node2 in Element)
{
XmlNode Element2 = (XmlNode)node2;
foreach (XmlNode node3 in Element2) // Colour
{
XmlNode Element3 = (XmlNode)node3; // (Intesity)
foreach (XmlNode node4 in Element3)
{
XmlNode Element4 = (XmlNode)node4;
if (Element4.Name == "intensity")
{
row[i] = Element4.InnerText.ToString();
results.Rows.Add(row);
row = results.NewRow();
}
}
}
i++;
}
}
//now return the DataTable
return results;
I require "color" as the column Header, I require intensity as the value for each color at a specific time
hope someone can help me?
thanks Craig.

Here's a simple solution for you that parses the entire XML file and loads it into a Data Set, which is later on used to bind the Data Source of the Grid View.
DataSet ds = new DataSet();
ds.ReadXml("xml file path"));
GridView1.DataSource = ds;
GridView1.DataBind();
