发帖数: 215 | 1 I want to extract certain texts from web pages. The page may contain many
links
and I have to click links to see whether contents of links are related or not.
If there are related contents, I will copy and save related paragraphs into
a text tile; if not, I need go back and check the next link.
Can anyone tell me that what language I should use? Will scripts do this work?
What kinds of script?
Many thanks! | s**i

发帖数: 3 | 3 python吧，regular expression据说比perl的要好使，我没用过perl，只是道听途说。
用re处理网页相当方便。
