如何從Xdocument中刪除節點而不指定節點的全名

我有一個XML，我正在刪除列表中存在的節點。 xml的節點以'Format'開頭，我想刪除這些節點，但目前我的方法無法處理它。我目前使用XDocument和Linq來刪除節點。可能有人解釋如何可以刪除其字「格式」開始的節點輸入XML是如何從Xdocument中刪除節點而不指定節點的全名

這是我

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(); 

     }

你嘗試'doc.Descendants（）。其中（E =>電子.Name.StartsWith（「Format」））。Remove（）;'？ –

VisualStudio給了我一個錯誤，我不認爲StartsWith是linq – Hitzz91

中的函數或者，也可以將它們添加到不必要的節點列表中。「格式」的沒有列出。（並且「UserID」被列出兩次） – Kevin

怎樣可以刪除節點的代碼先從單詞 '格式'

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