Abstract: As an high-class software reuse technique ,design pattern can simply reuse the succeed design and architecture .This article analyses the characteristic of HTML language version 4.0,and abstracts every tag of HTML language as an object.In the process for design ,it makes full use of composite pattern and simple factory pattern to avoid the use of complicated stack, clears the design of system and improves the agility and expansibility of the system.
