asp.net 读写 XML
using System.Xml;//初始化一个xml实例
XmlDocument xml=new XmlDocument();
//导入指定xml文件
xml.Load(path);
xml.Load(HttpContext.Current.Server.MapPath("../7in10.xml"));
//指定一个节点
XmlNode root=xml.SelectSingleNode("/root");
//获取节点下所有直接子节点
XmlNodeList childlist=root.ChildNodes;
//判断该节点下是否有子节点
root.HasChildNodes;
//获取同名同级节点集合
XmlNodeList nodelist=xml.SelectNodes("/Root/News");
//生成一个新节点
XmlElement node=xml.CreateElement("News");
//将节点加到指定节点下,作为其子节点
root.AppendChild(node);
//将节点加到指定节点下某个子节点前
root.InsertBefore(node,root.ChildeNodes[i]);
//为指定节点的新建属性并赋值
node.SetAttribute("id","11111");
//为指定节点添加子节点
root.AppendChild(node);
//获取指定节点的指定属性值
string id=node.Attributes["id"].Value;
//获取指定节点中的文本
string content=node.InnerText;
//保存XML文件
xml.Save(path);
xml.Save(HttpContext.Current.Server.MapPath("../7in10.xml")); --------------------编程问答-------------------- --------------------编程问答-------------------- try。。。。

C#获取HTML源码 --------------------编程问答-------------------- linq to xml --------------------编程问答-------------------- 刚刚搞错啦...不好意思....
--------------------编程问答-------------------- what are u what to do what what what!!
XmlDocument xdXML = new XmlDocument(); xdXML.Load("config.xml");
C#读取XML文件示例
1、config.xml文件:
<?xml version="1.0" encoding="utf-8"?>
<Address>
<HttpAddress>http://www.taian-seo.com</HttpAddress>
</Address>
2、
private void LoadConfig()
{
string xmlPath = Application.StartupPath + "\\config.xml";
try
{
XmlDocument xdXML = new XmlDocument();
xdXML.Load(xmlPath);
XmlNode node = xdXML.SelectSingleNode("//HttpAddress");
if (null != node)
{
txtHttpAddress.Text = node.InnerXml.Trim();
}
else
{
txtHttpAddress.Text = "";
}
}catch (FileNotFoundException)
{
MessageBox.Show("因缺少config.xml配置文件,而无法找到Web站点的地址!", "提示信息", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
catch (Exception)
{
MessageBox.Show("访问Web站点时地址未找到!", "提示信息", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}
