Regular expressions are used when grabbing blog park data, so friends who are not familiar with regular expressions can refer to relevant materials, which is easy to grasp, that is, they will spend some time in specific examples.

Now I would like to describe the process of capturing the data of the blog park. If any friends have better opinions, you are welcome to put forward them.

To use regular expressions to grab data, first create a regular expression to match, I recommend using regulator, this regular expression tool, we can first use this tool to piece together the regular expressions we want to use, and then use it in the program.

I found that the home page list of the blog park can be accessed through http://www.cnblogs.com/p1,p2.... This way to access directly, so that we can directly through the url to obtain data, rather than simulated data click event to virtual click on the next page of the button to get the data, more convenient. Because my goal is to grab some data, so keep it simple.

1. First of all, it is necessary to write the corresponding sql Helper class, which I believe many programmers will master. It is nothing more than the operation of adding, deleting, changing and checking. After we have created the sqlhelper class, we can begin the logical processing of fetching data.

two。 Create BlogRegexController

Public class BlogRegexController: Controller {public void ExecuteRegex () {string strBaseUrl = "http://www.cnblogs.com/p"; / / defines the base address for (int I =; I) of list data that can be accessed by the blog park.
