如何查找xml中的节点－－－－等待高人指点！！！

[dhdhdh]

我的.xml文件：
<root>
<class id="a">
<titile>titile</titile>
<detail>detail</detail>
</class>
<class id="d">
<titile>1</titile>
<detail>2</detail>
</class>
<class id="a">
<titile>111</titile>
<detail>222</detail>
</class>

</root>
请问我如何查找id="a"且titile="111"的节点！！！

楼主应该先去学一下XPath...

例:
using System;
using System.IO;
using System.Xml;

public class Sample
{
public static void Main()
{

XmlDocument doc = new XmlDocument();
doc.Load("booksort.xml");

//Create an XmlNamespaceManager for resolving namespaces.
XmlNamespaceManager nsmgr = new XmlNamespaceManager(doc.NameTable);
nsmgr.AddNamespace("bk", "urn:samples");

//Select and display the value of all the ISBN attributes.
XmlNodeList nodeList;
XmlElement root = doc.DocumentElement;
nodeList = root.SelectNodes("/bookstore/book/@bk:ISBN", nsmgr);
foreach (XmlNode isbn in nodeList){
Console.WriteLine(isbn.Value);
}

}

}
该示例使用文件 booksort.xml 作为输入。

<?xml version="1.0"?>
<!-- a fragment of a book store inventory database -->

he，你竟然找到了这个.xml文件，利害。
但是我找到该节点后，为何用document.removechid出错，急！！！！！！！！
