Abhay Dabholkar commented on NUTCH-585:
---------------------------------------

I been using this plugin for sometime and recently i wanted to use it to extract text based on url pattern
Example:
for http://x.y.z/?id=12 white-list will only look for div id=12
for http://x.y.z/?id=13 white-list will only look for div id=13

> We are using nutch to index our own web sites; we would like not to index certain parts of our pages, because we know they are not relevant (for instance, there are several links to change the background color) and generate spurious matches.
> We have modified the plugin so that it ignores HTML code between certain HTML comments, like
> <!-- START-IGNORE -->
> ... ignored part ...
> <!-- STOP-IGNORE -->
> We feel this might be useful to someone else, maybe factorizing the comment strings as constants in the configuration files (say parser.html.ignore.start and parser.html.ignore.stop in nutch-site.xml).
> We are almost ready to contribute our code snippet.  Looking forward for any expression of  interest - or for an explanation why waht we are doing is plain wrong!
