It is a list of colours and each colour has some attributes

I want to get few colors (White, Blue, Brown, Yellow)

and read its attributes and put it in a database

I managed to read one tag only and could not get its attributes

This is my code so far

        XmlDocument xmldoc = new XmlDocument();
        XmlNodeList xmlnode;
        int i = 0;
        string str = null;
        FileStream fs = new FileStream(@"c:\Output\1.xmi", FileMode.Open, FileAccess.Read);
        xmldoc.Load(fs);
        xmlnode = xmldoc.GetElementsByTagName("group1:White");
        for (i = 0; i <= xmlnode.Count - 1; i++)
        {
            str = xmlnode[i].Item("code").InnerText.Trim() + "  " + xmlnode[i].Item("ref").InnerText.Trim() + "  " + xmlnode[i].Item("mask").InnerText.Trim();
            MessageBox.Show(str);
        }

I got xmlnode[i] correct but no attributes !

how to read tags attributes?

Note that, group1 and group2 are not declared in the posted Xml.

For the question how to read tags attributes?, you could access to attribute, by calling .Attributes["AttributeName"], like :

....
xmlnode = xmldoc.GetElementsByTagName("group1:White");
for (i = 0; i <= xmlnode.Count - 1; i++)
{
    str = xmlnode[i].Attributes["code"].Value + "  " + xmlnode[i].Attributes["ref"].Value + "  " + xmlnode[i].Attributes["mask"].Value;
    MessageBox.Show(str);
}
....

I hope you find this helpful.
