parser needed

[Giulio]

I've got to take some data from a CSV file, so i need a good string parser
to recognize data to store in variables.
using google I found the code below.
that seems to be a good solution but I had some problems using it, which
libraries should I include?

Can someone suggest me any other libraries to do what I need?

thanx alot
Giulio

//// Get substring, chMagic is a character which

It's all written to use the MFC CString class and the stupid
windows type names. If you're not using Visual Studio, you're
probably hosed, keep looking.

Hi,

Try http://spirit.sourceforge.net/ spirit to parse the file.

Since it uses templates there is no need to compile against a library. If it
is a simple file (like csv) you can use a relatively simple parser (without
creating a ast).

the best parser you will get is a lex / yacc generated parser/lexer
If you intend to do lots of work with th eparser I suggest you to look
at those two tools, they are excellent tools for generating parsers.
