这是我的代码

 private static string RemoveUnnecessaryNodes(string inputXml)
        {
            // may move those nodes to a configuration file
            string[] unnecessaryNodes = new string[] { "ChangeType", "UserID", "TimeStamp", "DisplayFieldName", "CoreMessageObjectArray" , "WriteOpt", "EntityStatus", "ID", "DisplayName", "Sequence"};
            XDocument doc = XDocument.Parse(inputXml);

            foreach (string unnecessaryNode in unnecessaryNodes)
            {
                doc.Descendants().Where(e => e.Name == unnecessaryNode).Remove();
                /*string pattern = BuildRegexPattern(unnecessaryNode);
                inputXml = RemoveUnnecessaryNode(inputXml, pattern);*/
            }

            return doc.ToString();

        }

如何删除以单词＆＃39;格式＆＃39;开头的节点？

XDocument doc = XDocument.Parse(inputXml);
doc.XPathSelectElements("//*[starts-with(name(), 'Format')]").Remove();

如何在不指定节点全名的情况下从Xdocument中删除节点
