public class Test
{
    static void Main()
    {
        string xml = "<Ids><id>1</id><id>2</id></Ids>";

        XDocument doc = XDocument.Parse(xml);

        var list = doc.Root.Elements("id")
                           .Select(element => element.Value)
                           .ToList();

        foreach (string value in list)
        {
            Console.WriteLine(value);
        }
    }
}

// A string containing the XML data
string xml = "<Ids><id>1</id><id>2</id></Ids>";
// The list you want to fill
ArrayList list = new ArrayList();

XmlDocument doc = new XmlDocument();
// Loading from a XML string (use Load() for file)
doc.LoadXml(xml); 
// Selecting node using XPath syntax
XmlNodeList idNodes = doc.SelectNodes("Ids/id");
// Filling the list
foreach (XmlNode node in idNodes)
    list.Add(node.InnerText);

class FileFormat
    {
        public FileFormat(string path)
        {
            this.path = path;
        }
        public string FullPath
        {
            get { return Path.GetFullPath(path); }
        }
        public string FileName
        {
            get { return Path.GetFileName(path); }
        }
        private string path;
    }

List<FileFormat> Files =
        selectedNode
        .Descendants("Ids")
        .Elements("Id")
        .Select(x => new FileFormat(x.Value))
        .Where(s => s.FileName!=string.Empty)
        .ToList();
