Rails - Apr 2006 - FeedTools syntax question

http://www.mozdex.com/open.jsp?query=webhosting&start=10

in the above feed, can anyone tell me how to access the 
openSearch:totalResults element using feed tools? I can access the other 
elements, but I''m unsure what special meaning the colon carries or how
to
work with such items in feedtools

thanks in advance

whilst I''m on the topic of feedtools, has anyone been able to use it
with
the google web results from opensearch? I can''t find the URL for the
rss
feed for it....

The colon in an xml tag signifies a namespace. "openSearch" would be
the namespace prefix
and all tags in the document with that prefix are in that namespace.

If you look at the root element it declares the namespace:

xmlns:openSearch="http://a9.com/-/spec/opensearchrss/1.0/"

Note that the URL there is just being used as a URI... a unique identifier for
the
namespace. Giving it the prefix allows you to use the prefix in the tags instead
of having
to stick that whole URI in every tag in the namespace.

I don''t know anything about feedtools, but hopefully it has some
facility for dealing with
  namespaces... Any decent XML library should.

feed
FeedTools::Feed.open(''http://www.mozdex.com/open.jsp?query=webhosting&start=10'')
puts feed.find_node(''openSearch:totalResults'').text

''feed'' can be used as a simple REXML object
