Asp.net reads xml, and asp.net reads xml

Asp.net reads xml, and asp.net reads xml

This is suitable for students who have just learned asp.net. the great gods just skipped it. asp.net often has a lot of places where XML is used, such as the Association of provinces and cities nationwide, and some menu reads all have xml shadows, directly paste the code so that I can forget it when I use it later. I have clearly written the comments and can leave a message if I don't understand it.

/// <Summary> /// read the city list /// </summary> public void CityList () {StringBuilder sb = new StringBuilder (); xmlDocument xmldoc = new XmlDocument (); xmldoc. load (Server. mapPath ("/XmlData/City. xml "); // load xml XmlNodeList xmlnlist = xmldoc. selectNodes ("/Cities/City"); // read the xml node list for (int I = 0; I <xmlnlist. count; I ++) {sb. append ("<a href = \" index. aspx? Cityid = "+ xmlnlist [I]. attributes ["ID"]. value + "\"> "+ xmlnlist [I]. attributes ["CityName"]. value + "</a>"); // read the Value in the loop} citys = sb. toString ();} // ------ attached xml format ------ // <? Xml version = "1.0" encoding = "UTF-8"?> <Cities> <City ID = "218" CityName = "Nanning" PID = "20" ZipCode = "530000"> Nanning </City> <City ID = "219" CityName = "Liuzhou" PID = "20" ZipCode = "545000"> Liuzhou </City> <City ID = "228" CityName = "Hezhou" PID = "20" ZipCode = "542800 "> Hezhou </City> </Cities>

In addition, I have added the QQ logon function at www.weixh.net over the past few days. I am still studying it and will share the process with you after the review!

How to Use aspnet C # To Read xml

DataSet ds = new DataSet ();
If it is a file:
Ds. ReadXml (file path );

If it is a string:
XmlDocument xd = new XmlDocument ();
Xd. LoadXml (string );
XmlNodeReader xnr = new XmlNodeReader (xd );
Ds. ReadXml (xnr );

This will fill in the DataSet ..

Complete code
/// <Summary>
/// XML Resource Type
/// </Summary>
Public enum XmlType
{
File,
String
};
/// <Summary>
/// Read the XML resource to the able
/// </Summary>
/// <Param name = "source"> XML resource. The file is a path; otherwise, it is an XML string. </param>
/// <Param name = "xmlType"> XML Resource Type: file, string </param>
/// <Param name = "tableName"> table name </param>
/// <Returns> DataTable </returns>
Public DataTable GetTable (string source, XmlType xmlType, string tableName)
{
DataSet ds = new DataSet ();
If (xmlType = XmlType. File)
{
Ds. ReadXml (source );
}
Else
{
XmlDocument xd = new XmlDocument ();
Xd. LoadXml (source );
XmlNodeReader xnr = new XmlNodeReader (xd );
Ds. ReadXml (xnr );
}

Return ds. Tables [tableName];

How does aspnet read xml strings?

XmlDocument xmlDoc = new XmlDocument ();

If (! File. Exists (xmlFileName ))
{
Return string. Empty;
}
XmlDoc. Load (xmlFileName );
XmlNodeList nodes = xmlDoc. SelectNodes (keyPath );

Foreach (XmlNode node in nodes)
{
Foreach (XmlNode childNode in node. ChildNodes)
{
If (childNode. Name = keyName. ToUpper ())
{
String dataValue = childNode. InnerText;
Return dataValue;
}
}
}
