用C或者C++如何生成类似于ADO生成的xml文件？不用ADO

[confucius]

用ADO访问Oracle数据库，可以把数据库中的表生成下面格式的xml文件

我现在的问题是：如何不通过ADO，用C或者C++直接生成这样的文件，因为我的程序要在Linux上运行，需要把Oracle中的表数据
导出下面这样的xml，然后传给客户端使用，有没有现成的C或者C++代码？

数据输出直接采用C写成XML格式就可以啦。

ADO是微软公司的适用于各种类型数据的重要的高层接口,但是在LINUX下
没有相应这方面的技术支撑。
你要访问这些XML文件C语言可以使用LIBXML2解析库就可以了。

[dxing_1983]

直接用c写就可以了

自己写好慢，我测试了一下，自己写同样的表用时700毫秒，而ADO只用60多毫秒，另外一张表，记录比较多，我自己写的用时2秒左右，而ADO还是用时70毫秒左右
