Embodiment Construction

[0052]The core of the invention is that in the process that the content containing HTML codes passes through the server, the server can eliminate harmful codes in the codes by completing, filtering, correcting and transforming the codes. During the specific implementation, the content containing HTML code input by the user may be sent to the database through the server, and these codes shall be completed, filtered, corrected and converted by the server before being stored in the database, or stored in the database. During the process of displaying the HTML codes of the HTML codes to the client through the server, the server completes, filters, corrects and converts these codes.

[0053] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0054] Those skilled in the art know that HTML belongs to Docu...
