------------------------------------

Hi.. 

After swaping the parse-plugin.xml i.e. the following way .. (and turning off magic detection)

        <mimeType name="text/xml"> 
           <plugin id="parse-rss" /> 
          <plugin id="parse-html" />
        </mimeType> 

Hoping that parse-rss will pick-up the doc firs and not return NPE so out of 25 RSS URL with
1 round of fetch I managed to escape dedup with only 4 doc being indexed all other 21 docs
throw NPE .. 

Error parsing: http://rss.cnn.com/rss/cnn_warpcnn.rss: failed(2,200): java.lang.NullPointerException
Error parsing: http://rss.cnn.com/rss/cnn_ac360blog.rss: failed(2,200): java.lang.NullPointerException
Error parsing: http://rss.cnn.com/rss/cnn_marquee.rss: failed(2,200): java.lang.NullPointerException
Error parsing: http://rss.cnn.com/rss/cnn_gupta.rss: failed(2,200): java.lang.NullPointerException

I must be doing something sily there must be way to tell nutch to index using plugin X.. I
thought you do that turning magic off and using plugin-parse.xml .. no? am I missing something
.. Please let me know..

I am going to try the parse-feed now to see what happens. Issues regarding that I will post
in Nutch-444

Cheers

> allow Parser#parse to return a Map<String,Parse>. This way, the RSS parser can
return multiple parse objects, that will all be indexed separately. Advantage: no need to
fetch all feed-items separately.
