C applet that converts an INI file to an XML file

All-in-One programming by Song jingshan

In the past, I thought it would be nice to understand the file. When I realized it, I couldn't even understand it ~

The INI file consists of several sections with names starting from []. Each section is composed of several key = value, and the equal sign can be left or right by several spaces or tables. Each line is equal to or equal; it starts with a comment. There are multiple empty row bins between two sections.

Now that XML is emerging, the INI file is a bit earthy. Convert the INI file to an XML file

Ini

; Configuration of HTTP
[Http]
Domain = www.mysite.com
Port = 8080
Cgihome =/cgi-bin

; Configuration of DB
[Database]
Server = MySQL
User = myname
Passwoed = toopendatabase

XML

<! -- Configuration of HTTP -->
<Http>
<Domain> www.mysite.com </domain>
<Port> 8080 </port>
<Cgihome>/cgi-bin </cgihome>
</HTTP>

<! -- Configuration of DB -->
<Database>
<Server> mysql </Server>
<User> myname </user>
<Passwoed> toopendatabase </passwoed>
</Database>

The following is the source code I wrote. I think the failure is to read the entire code by row:

Code:

9. Const char match_char [] = {';', '[', '= '};
11. /* The Conversion Result is "empty" and "empty */

14. {
