HashMap - linkParams

[Marco PV <nu...@hotmail.com>]

Hi,

How to add new parameter at HashMap  linkParams?
To follow img src="iamge_url"

linkParams.put("img", new LinkParams("img", "src", 1));

      linkParams.put("a", new LinkParams("a", "href", 1));
      linkParams.put("img", new LinkParams("img", "src", 1));
      linkParams.put("area", new LinkParams("area", "href", 0));
      linkParams.put("frame", new LinkParams("frame", "src", 0));
      linkParams.put("iframe", new LinkParams("iframe", "src", 0));

What's the difference between 0 and 1?

Also, to be able to get iamge src urls, I've changed (at 
conf/nutch-default.xml)
<name>db.ignore.internal.links</name>
  <value>false</value>

Any help welcome,
Thanks

This should be:

> linkParams.put("img", new LinkParams("img", "src", 0));

0 means this element has no children, so there is no need to process 
sub-nodes. 1 means that at least one child node is expected.

You also need to allow the image file extensions in the regex-urlfilter.txt.
