This might help you.

这可能超出您的范围，但是您可以使用Lexx和Yacc解析器(例如Bison)来生成所需的解析器.

这是非常强大的功能，但是您需要使用C与C ++代码进行接口，但这是可能的.

我本人已经为类似HTML的语言完成了XML兼容的解析器.

This might be a bit out of your scope but you could use a Lexx and Yacc parser such as Bison to generate a parser for what you need.

This is very powerful but you''ll need to use C to interface with your C++ code but it is possible.

I myself have done an XML compliant parser for an HTML like language.

I used this book to explain about the concepts and it was very helpful in starting off the parser.

this was also very useful.
