Marcin Okraszewski updated NUTCH-488:
-------------------------------------
Attachment: ignore_tags_v3.patch
OK, yet another approach based on Doğacan comments. Sorry for delay, but I
didn't notice the comment earlier.
- I didn't notice the conf.getStrings() method. Thanks for hint :)
- I did made the backward compatibility with the "use_action" param, but it
works a bit different now, if there is no value set. Now, default is that it
should use the forms. But it can be dropped with ignore_tags setting if not
specified. If someone has the use_action set to true explicite, then it cannot
be overridden by the ignore_tags. It is still a bit inconsitent, but it is
understandable that specific setting (use_action) has precedence. If default is
"false" then if you do not have "use_action" defined and not added to
ignore_tags, then one could expect that form is taken. But it wouldn't be.
Keeping the backward compatibility make the code a bit clumsy :( ... and I
think I've made it over flexible, but that was the cleanest solution here.
- For the repeating if; I agree, it is error prone, but on the other hand it is
easy to understand. I didn't quite understand Dogacan's proposal :( but I think
I did something acceptable - simply remove all specified tags from link params.

> Issue Type: Improvement
> Affects Versions: 0.9.0

> NekoHTML parser use a method to extract all outlinks from the HTML page. It
> will extracts them from the HTML content based on the list of param defined
> in the method setConf(). Then this list of links will be truncated to be
> limit to the the maximum number of outlinks that we'll process for a page
> defined in nutch-default.xml (db.max.outlinks.per.page = 100 by default ) and
> finally it will be go through all urlfilter defined.
> Unfortunetly it can happen that the list of outlinks is more than 100, so it
> will truncated the list and could remove some relevant links.
> So I've added few options in the nutch-default.xml in order to enable/disable
> the extraction of specific HTML Tag links in this parser (SCRIPT, IMG, FORM,
> LINK).
