Great article. Thanks. I have found Yahoo Pipes to be very powerful, but like you said a bit difficult to master. I've written about screen scrapping using Yahoo Pipes in the past: http://jlorenzen.blogspot.com/2008/10/using-yah...

Seems like you have everything you need to share an article on using pipes and GAE to collect RSS(es) and email them daily instead of relying upon google feedburner :)

Ah, maybe we are talking past one another. The code on this page is used to make call outs in the middle of a pipe execution in order to change the final result, not actually display those results on an html page. To do that I suggest you just use the code in the badges that Yahoo! Pipes gives you when you choose "Get Pipe as Badge" on a Pipe's homepage. Here is an example:

That HTML should be enough to show that pipe on your page. If I'm still confused about what you are trying to accomplish, please tell me the end result you are looking for.

Ok. So, lets pretend I'm 5. So, I copied your pipes and the GAE Code placed it on my appspot.com location. so i've got app.yaml, and the xyz.py What would I need to do - to view the pipe JSON on my appspot.com site? Assumption is a wee bit of javascript on a page. Correct? Meaning, i need to write a little page that takes the post and makes it visible - yes? I'm very bright. If your in a cave with no light, and blind. I'm the sun.

That link only accepts JSON POSTs so nothing really should come from it at all unless you POST JSON to it and then it will return what you post. Maybe you expected something else? You can test it out by cloning the pipe above and changing the input feed.

I just tested the pipe that uses it at:

http://pipes.yahoo.com/spul...

And that Pipe seems to mirror the RSS feed just fine. What kind of error are you seeing?

Does this still function. Wrote it quickly and never had it work then went to your appspot and had blank screen as well. What am I doing wrong?

You need to either call the pipe on demand when you want the web service to be executed or you can subscribe to the pipe in an RSS reader like My Yahoo, Google Reader, Bloglines or something similar that will poll it periodically.

How do you ensure that the pipe gets run with all the feed content?
If you dont access the pipe, it looks like nothing gets passed to the webservice.

Thanks for the article. Great information!

I copied your example and python code and uploaded it but I keep getting an error in my pipe saying * Web service failure:
An Error Occurred
405 Method Not Allowed

Do you have any idea why?

Nice article.

By the way, can’t you include simplejson using

“from django.utils import simplejson”?

You sure can. I didn't know that was in there. Thanks!
