Abstract

The invention discloses a processing system of style sheet, comprising a creating element of style document, a creating element of style attribute type and a depositing element. The creating element of style document is used for obtaining the parasitifer name list of the style and the style block from the source code document of web page and then creating the style document, wherein, the style document comprises the corresponding relationship of the parasitifer name list of the style and the style block, the style block comprises one or more style rules described by texts and each style rule comprises the described name and the value of the attribute. The creating element of style attribute type is used for converting the style rules described by texts of the style text into the style rules described by values and then creating the style attribute type which comprises the style rules described by values. The depositing element is used for depositing the style attribute type to the corresponding node elements of the HTML tree. The invention also discloses a corresponding method. The invention is suitable for equipment with scarce system resources, such as mobile phone, and can reduce the occupation of the system resources, therefore can improve the user experience greatly.

Description
