Using Wget to download an entire rss feed

Im trying to move a Drupal sites content http://www.philcooke.com/rss.xml using wget, but I am unable to download more then the 10 most recent stories. Ive set the rss feed in the Drupal admin to set rss feeds to sh开发者_StackOverflow中文版ow 30 items per feed. Ive done some searching, but I cant seem to find a way to have this display "all" and then use wget to download the posts.

If anyone knows of another way to download all of the posts (and comments for that matter) I wouldnt be opposed to trying that out as well, as at this point, Im willing to give any xml importing method a try. I should also mention the site runs Drupal 5.2 and Im trying to move it to Wordpress 3.0.1

You could use the views data source module to re-create a rss feed of any length - http://drupal.org/project/views_datasource
