A Brief Introduction to boost Regular Expression Library

Address: http://www.cppblog.com/walkspeed/archive/2007/12/28/39823.html

Header file RegEx. HPP

Common classes
Boost: RegEx Regular Expression

Boost: cmatch uses the char array as the container to store matching return values.
Boost: smatch uses STD: string as the container and stores the matching return value.

Boost: regex_match matchAlgorithm
Boost: regex_search Search Algorithm
Boost: regex_replace replacement algorithm

Simple Example

# Include <iostream>

# Include <boost/RegEx. HPP>

Int main (INT argc, char * argv [])
{
Char * Buf = "this is boost: RegEx example ";

Boost: RegEx exampleregex ("Boost: RegEx ");
Boost: cmatch result;

If (boost: regex_search (BUF, result, exampleregex ))
{
STD: cout <result. STR () <STD: Endl;
}

Return 0;
}

Compile: G ++-g-wall-O0 Reg. CC-O reg-lboost_regex// Boost_regex the Regular Expression Library requires additional installation

Note the inclusion of RegEx. HPP. You need to set the seat of the boost header file in the development tool.
