| Abstract: | Proposes a method of information filtration algorithm based on regular expression by ana- lyzing the current structure of web page. Comparing with traditional method, the new algo- rithm is more efficient and convenient to be utilized with high precision. Combining the class of Regex, MatchCollection and Match together, implements the algorithm by C# in the envirnment of Visual Studio.NET 2003. |
