As far as i know, Boost.Xpressive treats only std::string and C-like strings.
Not so. Both Boost.Xpressive and Boost.Regex work on bidirectional iterator.
What i need to do for work with text files? Put them inside a std::string?
That's one way. A more efficient way would be to memory-map the file, which I think you can do portably using Boost.Interprocess. That should give you a random-access iterator to the source file.
About the performance, the files has approximately 10^3 lines, the search and replace will be an issue?
You should use the version of regex_replace that takes an output iterator, and either write into a string or vector. They both grow their capacity exponentially (or should if your STL implementation is worth anything), so this is quite efficient. Or, with an ofstream iterator, you can write directly to a temporary output file. I think the latest version of Boost.Filesystem has a portable way to create temporary files. Then you can do whatever you want with the temp file.
