     <abstract> 
      <cepara>ABSTRACT: Stroke remains worlds second leading cause of mortality; and globally most frequent cause of long-lasting disabilities. The ischaemic pathophysiologic cascade leading to neuronal damage consists of peri-infarct depolarization, excitotoxicity, inflammation, oxidative stress, and apoptosis. Despite plethora of experimental evidences and advancement into the development of treatments, clinical treatment of acute stroke still remains challenging. Neuro-protective agents, as novel therapeutic strategy confer neuro-protection by targeting the pathophysiologic mechanism of stroke. The aim of this review is discussion of summary of the literature on stroke pathophysiology, current preclinical research findings of neuroprotective agents in stroke and possible factors that were responsible for the failure of these agents to translate in human stroke therapies.</cepara>

，但我需要所有的子元素

 <author Seq="0"> 
      <Inital>A.El</Inital> 
      <Surname>Khattabi</Surname> 
      <Givenname>Abdelkrim</Givenname> 
     </author>

如何单独删除根标签。为此，我遵循以下代码

XDocument CarXML = new XDocument(); 
     CarXML.Add(Root); 
     CarXML.Descendants("root").Remove(); 
     CarXML.Save(@"CAR.XML");

但此代码删除所有xml标记。如何单独删除根元素。我需要的子元素

可能的重复[如何删除C＃中的根元素/]（http://stackoverflow.com/questions/17503619/how-to-remove-root-element-in-c） –

答

CarXML.ReplaceNodes(CarXML.Descendants("author").FirstOrDefault());

这取代了XML的名为author第一传人的全部内容。
