在XML文件中搜索记录 [英] Searching Records in XML File

问题描述

我要搜索从xml文件中搜索记录的文件.下面是我的xml文件.




dtable
id 2 id
名称jigar名称
phone_no 12345 phone_no
/dtable

dtable
id 3 id
姓名ajay姓名
phone_no 7777 phone_no
/dtable

dtable
id 4 id
名字bhargav名字
phone_no 4444 phone_no
/dtable



我想做的是，当用户搜索id ="2"时，它应该显示姓名和电话号码.我的问题是如何从xml文件中搜索?有什么帮助? "h2_lin">解决方案

尝试以下代码

 XmlDcoument xDoc =新的XmlDocument();
xDoc.Load("YourXml.XML");
 
XmlNode xNode = xDoc.DocumentElement.SelectSingleNode("dtable [id = 2]"); 

这将为您提供id = 2
的dtable节点
现在，要读取其他节点，请使用以下

 foreach(xNode中的XmlNode子级)
{
   Response.Write(child.LocalName);
   Response.Write(:");
   Response.Write(child.InnerText);
   Response.Write("\ n");
} 

希望能有所帮助.如果是这样，请将答案标记为解决方案和/或投票.

谢谢

i want to do is,When user searches for id="2",it should display name and phone no.My question is how to search from xml file?any help is appreciated.

解决方案

Try following code

XmlDcoument xDoc = new XmlDocument();
xDoc.Load("YourXml.XML");
 
XmlNode xNode = xDoc.DocumentElement.SelectSingleNode("dtable[id=2]");

This will give you the dtable node which has id=2

Now, to read the other node use following

foreach (XmlNode child in xNode)
{
   Response.Write(child.LocalName);
   Response.Write(":");
   Response.Write(child.InnerText);
   Response.Write("\n");
}

Hope that helps. If it does, mark the answer as solution and/or upvote.
