是这样的,我用下面的程序可以删除节点<User></User>中的所有内容,但是我却无法删除<User></User>节点
protected void DeleteButton_Click(object sender, EventArgs e)
{
XmlDocument Doc = new XmlDocument();
Doc.Load(Server.MapPath(".\\db\\dbGuest.xml"));
XmlNodeList NodeList = Doc.SelectSingleNode("dbGuest").ChildNodes;
foreach (XmlNode xn in NodeList)
{
XmlElement xe = (XmlElement)xn;
XmlNodeList node = xe.GetElementsByTagName("Name");
if (node.Count > 0)
{
if (node[0].InnerText == ddlName.SelectedItem.Text)
{
xe.RemoveAll();
break;
}
}
//xn.RemoveAll();
}
Doc.Save(Server.MapPath(".\\db\\dbGuest.xml"));
DataBind();
}
XML文件:
<?xml version="1.0" standalone="yes"?>
<dbGuest>
<User>
<Name>asfew3ere1sfasf</Name>
</User>
<User>
<Name>asfew3243232cvd1sfasf</Name>
</User>
</dbGuest>
例如我按下了DeleteButton按钮要删除第二个<User></User>我想得的的XML文件是这样的:
<?xml version="1.0" standalone="yes"?>
<dbGuest>
<User>
<Name>asfew3ere1sfasf</Name>
</User>
</dbGuest>
但是我实际上得到的结果是这样的:
<dbGuest>
<User>
<Name>asfew3ere1sfasf</Name>
</User>
<User>
</User>
</dbGuest>
请问如何解决? |
