How to convert an INI file to XML

xml| Conversion

For the development of C/s system programmers, INI file is not unfamiliar, when the XML becomes more and more popular, how to convert the original INI file to XML becomes a tricky thing. Below I put this aspect of the code dedicated to everyone, if there are any bugs, welcome criticism: qieyj@cape.com.cn.
