An Approach of Extracting Web Information Based on HTMLParser

Abstract

Now many applications need to analyze various detail contents of web pages. How to extract web information quickly and effectively becomes very important. Web information is primarily expressed by HTML. HTMLParser is an open project of SourceForge.net and can parse HTML in either a linear or a nested fashion. This paper analyzes the principle of extracting web information based on HTMLParser. In addition, it gives an approach of implementing web information extraction with the classes and methods provided by HTMLParser. At last, we demonstrate the detailed process of web information extraction by an example.

Water Absorption of Basalt Fiber and Mineral Glass Powder Reinforced Wood Composites

“…Mineral glass is a recently developed material, made from volcanic lava, which is corrosion resistant, heat resistance, wear resistant, environmental friendly, impermeable and very strong. Basalt fiber is made from basalt rock, a typical volcanic lave, whish is also environmental friendly and impermeable [6]. In order to improve the adhesion of interface, basalt fiber and mineral glass powder were treated with silane coupling agent at the concentration of 0.75%.…”
