Thanks in advance.

No help from XPath here. Doctype is out of XPath data model. But after
all it's easy to select Doctype - its placement is fixed and
DocumentType property of XmlDocument class returns it. So you can remove
it and insert a new one.
Here is a sample:
doc.RemoveChild(doc.DocumentType);
XmlDocumentType doctype = doc.CreateDocumentType("root",
null, "foo.dtd", null);
doc.InsertBefore(doctype, doc.DocumentElement);
