C＃的LINQ to XML，删除基于一个标签的标签名

Question

删除标签New，如果下一个标签是<b>

这里是我的xml文件

<tag> 
    <New>some content</New> 
    <b> bold </b> 
    <New> content two </New> 
    <p> p tag </p> 
</tag> 

输出是其内容

<tag> 
    <b> bold </b> 
    <New> content two </New> 
    <p> p tag </p> 
</tag> 

这里是我的代码

XElement rootImg = XElement.Parse(xml string variable); 

IEnumerable<XElement> img = 
    from el in rootImg.Descendants("New").ToList() 
    select el; 

foreach (XElement el in img) 
{ 
    //what am i going to do here? 
} 

Answer 1

foreach (XElement el in img.ToArray()) 
{ 
    var afterElement = el.NodesAfterSelf().FirstOrDefault() as XElement; 
    if (afterElement != null && afterElement.Name == "b") 
    { 
     el.Remove(); 
    } 
}
