Hi,
As I can see this xml is not valid and I think that it can not be loaded with any XML parser. You need to escape "&" char (replace it with "&") and then you will be able to load file.
I made you a simple example using C# LinqToXml[^].
Use LINQPad[^] to run this example:

var creators = from c in doc.Descendants(dc + "creator").Descendants(rdf + "li")
select c.Value;
creators.Dump("Creators");
}
As you can see there are many namespaces defined in your xml and if you want to find/select element within your xml you must write fully-qualified element name (namespace+name).
