Storing XML post source with Drupal

  Tim Cullen took me up on my feature request for blogging tool vendors.
  A few links.
  1. This is my Drupal test website.
  2. My username is Dave Winer. He mailed me my password.
  3. The URL of the MetaWeblog API is here.
  I think I have everything I need to test it.
  Hours later...
  After a lot of fumbling and guessing and support from Tim, I was able to get metaweblog.newpost to create a new post.
  http://yiwen.pair.com/schange/testbed/node/6
  Let's see if, when I do a metaweblog.getpost, I get back the source code.
  metaweblog.getpost failed, but this time I got an error response. (Earlier errors were silent.)
  The server, yiwen.pair.com, returned error code -32602: Server error. Invalid method parameters.
  The only one that seems could be causing the problem is the postid which I sent across as the number 6.
  Then I changed it to the string 6 and it worked. :-)
  Did it return a value for postSource? It did. Was it what I sent?
  Yeah it looks pretty good. :-)
