Extracting comments

Hi to all,
I am working in Crawling applications to crawl the various news sites, the problem i'm facing is to extract the comments from these sites . In some sites it is very easy to extract comments as comments are displayed in source code but in most of cases these sites used DISQUS api for comments, in that cases comments are not displayed on source code. even i analysed about the java scripts they are using for this but i didn't find any solution . Is there anybody giving me the idea how to extract the comments from these sites.


Thanks in advance

Is this a java programming problem? Can you show what the program reads and outputs and explain what is wrong with that output?
