Xmltextwriter usage Diary

Use xmltextwriter to generate the following XML:

 

<? XML version = "1.0" encoding = "UTF-8" standalone = "yes"?>
<Pkboy kind = "Site">
<Command name = "price" Object = "game" Password = "ASDFASDF">
<Game name = "World of Warcraft">
<Server name = "Warcraft Server 1">
<Item name = "gold coin" kind = "gold" quantity = "12" gross = "0.5005" maxdollar = "99" mindollar = "88" rate = "6.88"/>
</Server>
</Game>
</Command>
</Pkboy>

 

UsedCode:

 

Public static string generatepricexml (pricestruct ps, encoding encode)
{
String xml = string. empty;

Using (memorystream MS = new memorystream ())
{
Using (xmltextwriter xtw = new xmltextwriter (MS, encode ))
{
Xtw. Formatting = formatting. indented;
// Xtw. indentation = 2;

Xtw. writestartdocument (true );

// Pkboy Node
Xtw. writestartelement ("pkboy ");
Xtw. writeattributestring ("Kind", "Site ");
// Command node
Xtw. writestartelement ("command ");
Xtw. writeattributestring ("name", "price ");
Xtw. writeattributestring ("object", "game ");
Xtw. writeattributestring ("password", PS. Password );

// Game Node
Xtw. writestartelement ("game ");
Xtw. writeattributestring ("name", PS. gamename );

// Server node
Xtw. writestartelement ("server ");
Xtw. writeattributestring ("name", PS. servername );

// Item Node
Xtw. writestartelement ("item ");
Xtw. writeattributestring ("name", PS. itemname );
Xtw. writeattributestring ("Kind", PS. itemkind );
Xtw. writeattributestring ("quantity", PS. quantity. tostring ());
Xtw. writeattributestring ("gross", PS. Gross. tostring ());
Xtw. writeattributestring ("maxdollar", PS. maxdollar. tostring ());
Xtw. writeattributestring ("mindollar", PS. mindollar. tostring ());
Xtw. writeattributestring ("rate", PS. rate. tostring ());

// Colse item Node
Xtw. writeendelement ();
// Close the server node
Xtw. writeendelement ();
// Close game Node
Xtw. writeendelement ();
// Close command node
Xtw. writeendelement ();
// Close pkboy Node
Xtw. writeendelement ();
// Close document
Xtw. writeenddocument ();

Xtw. Flush ();
Xml = encode. getstring (Ms. getbuffer (), 0, (INT) ms. Length );
}
}
Return XML;
}

 

The XML format is as follows:

<? XML version = "1.0" encoding = "UTF-8" standalone = "yes"?>
<Pkboy kind = "result">
<Result success = "false">
<DATA> This is result data </data>
<Error kind = "databaseerror">
<Message> database connection failed </message>
</Error>
</Result>
</Pkboy>
