The regular expression (regex), using Boost's regex header file, is the new standard for c++11, but gcc4.8.1 is not fully supported, so use boost library; Specific installation: http://blog.csdn.net/caroline_wendy/article/details/17282187 The writing specification of regular expressions, taking ECMAScript as an example, using iterators can traverse the original string and output all the strings conforming

Next: Regular expression (regex) Error usage causes a feature vulnerability, we continue to comb, regular expression error use, resulting in functional design vulnerabilities (bugs), do the web, need to master a lot of knowledge, web development this work, in the domestic also more than 10 years, many developers, are through: training ( self-study)-> imitate-> do project, such a process. Many of them have changed and become web development engineers.

C # provides a very powerful function for the use of regular expressions, which is the Regex class. This package is included under the System.Text.RegularExpressions namespace, and the DLL where the namespace is located basically does not need to be added separately in all project templates and can be used directly.1.
