I am reading a xml file and trying to populate one of the nodes into a dropdownbox. I've managed to do this. However the dropdownbox shows every node innertext and I need to get rid of the duplicates.

XmlDocument doc = new XmlDocument();


            XmlNodeList nodes = doc.SelectNodes("JOBS/JOB/CATEGORIES/CATEGORY");

            foreach (XmlNode node in nodes)

             DropDownList1.Items.Add(newListItem(node.FirstChild.InnerText, node.LastChild.InnerText));

The following usis Xml.Linq (I prefer this to the original Xml classes in .Net 2.0). Caveat - I did this from memory, so you may have to tweak it a little).

XDocument doc = XDocument.Load(xm_Uri);
XElement root = doc.Element("JOBS/JOB/CATEGORIES");
foreach (XElement element in root.Elements())

This does not answer the question, AT ALL.
You can use the ListBox (which is what your DropDownBox is I assume) method: DropDownList1.Items.Contains(entry) as follows:
  foreach (XmlNode node in nodes)
            { DropDownList1.Items.Add(newListItem(node.FirstChild.InnerText, node.LastChild.InnerText));

This will check to see if the new entry is already in the list and only add it if not.

Hope this helps.
