救急，读配置文件，~~~

<?xml version="1.0" encoding="utf-8" ?>
<rundefine>
rundefine
<bookname>name1</bookname>
</book>
<book1>
<bookname>name2</bookname>
<bookname2>name3</bookname2>
</book1>
</rundefine>
怎么样得到节点<book>、<book1>和各子节点的个数和值，c# 语言，谢谢各位兄弟姐妹了~~~~~~~~~~~
例如：求出rundefine下面有几个<book>,<book1>的节点和对应的值，循环<book>或是<book1>，得到下面的子节点和子节点的值

[wartim]

<?xml version="1.0" encoding="utf-8" ?>
<rundefine>
</book>
<bookname>name1 </bookname>
</book>
<book1>
<bookname>name2 </bookname>
<bookname2>name3 </bookname2>
</book1>
</rundefine>

xpath:
book: /rundefine/book
book1: /rundefine/book1
bookname:/rundefine/book/bookname
/rundefine/book1/bookname
bookname2:/rundefine/book1/bookname2

<?xml version="1.0" encoding="utf-8" ?>

我实在是看不懂，能不能来个c#版的，这里谢过了

XmlTextReader xreader = new XmlTextReader(xml文件的路径);
XmlDocument xdoc = new XmlDocument();
xdoc.Load(xreader);
xreader.Close();
XmlNode xnode = xdoc.DocumentElement;
XmlNodeList xnodelist =xdoc.GetElementsByTagName(字段名);
我以前写的一段代码，具体应用可以baidu查一下XmlDocument和XmlNode等用法

[skotben2008]

XmlDocument x = new XmlDocument();
x.Load(Application.StartupPath+"\\a.xml");
XmlNodeList n = x.SelectNodes("/root/a");
foreach (XmlNode xm in n)
{
for (int i = 0; i < xm.Attributes.Count; i++)
{
richTextBox1.AppendText(xm.Attributes[i].Name + "--" + xm.Attributes[i].Value + "\r\n");
}
XmlNodeList nl = xm.ChildNodes;
foreach (XmlNode no in nl)
{
if (no.NodeType == XmlNodeType.Element)
richTextBox1.AppendText(no.Name + "--" + no.InnerText + "\r\n");
}
}

结果：
book 1
book 2
book1 aa
book1 bb
book2 dd
book2 ee

楼上回答的都对哈

[wuyq11]

System.Xml.XmlDocument dom = new System.Xml.XmlDocument();
dom.LoadXml(xml);
foreach (System.Xml.XmlNode node in dom.ChildNodes)
{
if(!node.Name.Equals("xml"))
Response.Write(GetNode(node)+"<BR>");
}
string GetNode(System.Xml.XmlNode node)
{
string str = node.InnerText;
if (node.HasChildNodes)
{
str = "";
foreach (System.Xml.XmlNode n in node.ChildNodes)
{
str += GetNode(n);
}
str += "<BR>";
}
return str;
}

[wuyq11]

System.Xml.XmlDocument xmlDoc= new System.Xml.XmlDocument();
xmlDoc.LoadXml("");
XmlNode xn=xmlDoc.SelectSingleNode("rundefine");
XmlNodeList xnl=xn.ChildNodes;
foreach(XmlNode xnf in xnl)
{
XmlElement xe=(XmlElement)xnf;
XmlNodeList xnf1=xe.ChildNodes;
foreach(XmlNode xn2 in xnf1)
{
Console.WriteLine(xn2.InnerText);
}
}

用XmlDocument

[oasistree]

Mark,正在学习xml

[huoyingyangjie]

- -!哥教你
public void read()
{

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load("Load.xml");//Loading.xml是你的xml文件名，如果你的文件在debug下面那么直接写文件名就可以了，如果不在就写绝对路径。

XmlNodeList nodeList = xmlDoc.SelectSingleNod("rundefine").ChildNodes;//获取bookstore节点的所有子节点
foreach (XmlNode xn in nodeList)//遍历所有子节点
{
XmlElement xe = (XmlElement)xn;//将子节点类型转换为XmlElement类型

XmlNodeList nls = xe.ChildNodes;//继续获取xe子节点的所有子节点

foreach (XmlNode xn1 in nls)//遍历
{
XmlElement xe2 = (XmlElement)xn1;//转换类型
那么xe2.name就是你想要的值；什么bookname1啊bookname2啊bookname3你都可以获得；

}


xmlDoc.Save("Load.xml");//保存。
}
就这样简单，更新啊，修改啊，写入都可以。不过哥要玩Warcraft了，再见。
还有你如果有其他什么节点，在foreach就可以了，程序是很简单的，就看你怎么想

[SimpleM]

LZ只需要看楼上几位用两层foreach循环输出的就可以了
