XML 如何删除一个指定的节点呢

[bg4rhm]

<Root>
<Abc>
<Bcd>
<A>33</A>
<B>ss</B>
</Bcd>
<AAA>
<SD>33</SD>
</AAA>
</Abc>
</Root>
如何指定删除 //Root//Abc//Bcd
即结果为：
<Root>
<Abc>
<AAA>
<SD>33</SD>
</AAA>
</Abc>
</Root>

关注中，XML节点删除，偶也想知道，顶

System.Xml.Linq.XDocument doc = System.Xml.Linq.XDocument.Load("file.xml");
            var query = from e in doc.Element("Root").Elements("Abc").Elements("Bcd")
                        select e;
            foreach(XElement xe in query)
            {
                xe.Remove();
            }

找到这个node //Root//Abc//Bcd ， 然后用node.ParentNode.RemoveChild(node)来删除，就是先找到这个node的parent，再删除它，嘿嘿

using System.Xml;
public partial class _Default : System.Web.UI.Page 
{
    protected void Page_Load(object sender, EventArgs e)
    {
        XmlDocument doc = new XmlDocument();
        doc.Load(Server.MapPath("data.xml"));
        XmlNode book = doc.SelectSingleNode ( "//Root/Abc/Bcd" );
        book.ParentNode.RemoveChild(book)
        doc.Save ( Server.MapPath ( "data.xml" ) );
    }
}

[我自横刀香甜笑]

XmlDocument doc = new XmlDocument();
doc.LoadXml("<Root><Abc><Bcd><A>33 </A><B>ss </B></Bcd><AAA><SD>33 </SD></AAA></Abc></Root>");
XmlNode root = doc.DocumentElement;
XmlNodeList list = root.SelectNodes( "descendant::Abc/Bcd" );
foreach( XmlNode node in list )
{
XmlNode parent = node.ParentNode;
parent.RemoveChild( node );
}
