Question

Answer 1

+2 A:

You can try something like this using Linq-to-XML (.NET 3.5 and up):

XDocument doc = XDocument.Load("yourfile.xml");

var mediaTags = doc.Descendants("media");
int num = mediaTags.Count();

// find one particular node, e.g. by inspecting it's "tid" attribute
XNode node = mediaTags
      .FirstOrDefault(x => x.Attribute("tid").Value == 
                               "{274BD12B-5E79-4165-9314-00DB045D4CD8}");

// if node is found - remove it from XDocument
if(node != null)
{
   node.Remove();

   // save file again
   doc.Save("Your-new-file.xml");
}

Answer 2

+2 A:

You have two options:

Load the file using the System.Xml.XmlDocument class.
Load the file using the System.Xml.Linq.XElement class.

The easiest is probably using XElement. (This is completely untested code.)

XElement document = XElement.Load("path to the file");

List<string> sources = new List<string>();
foreach (var mediaElement in document.Descendents("media"))
{
   if (sources.Contains((string)mediaElement.Attributes("src"))
   {
      mediaElement.Remove();
   }
   else
   {
      sources.Add((string)mediaElement.Attributes("src"));
   }
}

document.Save("path to the file");
