Title The special data extraction of the eml file and its way to implement
Abstract
Using the computer to send and receive E-mail has become a habit in People's Daily life, while the eml file is general format file of various software, to study how to correctly parse eml file is very important and significant. Using the program to implement the intelligent of parsing the eml file will a be great convenience to read E-mail. This article through the introducing of the RFC822 and MIME protocol, using the protocol specified in specification, presents an analytic algorithm to parse eml file. By design program, writer successfully completed the program which can read eml file automatically and intelligently. This paper first presents the research background of eml file parsing and the required knowledge. Through the study of basic knowledge, the author has understood the working principle of email, and then designed the algorithm to resolve the eml file. According to the algorithm and the using of visual c + +，the author wrote a intelligently program to parse eml file, which was tested by an example.
