[MTOS-dev] Developing action streams

[John Eckman]

Hello all -

First, is there a better place to ask questions about the Action  
Streams plugin?

These two pages both fail on my OpenID:
	http://plugins.movabletype.org/action-streams/
         http://www.movabletype.org/2008/01/building_action_streams.html

But even if I could log in I'm not sure comments are the best place  
for this kind of query.

I'm trying to build an action stream for the Activity Streams plugin,  
on MTOS 4.1, to show items added to an Amazon wishlist.

Here's the relevant info from the config.yaml I'm trying to use:

name: Amazon
id: amazon
key: amazon
description: Fetches from Amazon Wishlist Feed
profile_services:
     amazon:
         name: Amazon Wishlist
         url: http://www.amazon.com/gp/registry/wishlist/%s
         ident_example: http://www.amazon.com/gp/registry/wishlist/xxxxxxxxxxxxx
         icon: images/amazon.png

action_streams:
     amazon:
         purchased:	
             name: Purchased
             description: Items added to amazon wishlist
             html_form: 'New music purchase: <a href="[_2]">[_3]</a>'
             html_params:
                 - url
                 - title
             url: 'http://www.amazon.com/gp/registry/wishlist/{{ident}}'
             identifier: url
             scraper:
                 foreach: //tbody[@name]
                 get:
                     thumbnail:
                         - //tr/td[@rowspan="4"]/a/img
                         - @src
                     title:
                         - //tr/td[@class="small"]/b/a
                         - TEXT
                     url:
                         - //tr/td[@class="small"]/b/a
                         - @href


Questions:
- Any obvious reasons why this doesn't work? Can't seem to match the  
img, which is inside a td with a rowspan of 4.

- Is there a log anywhere of what the scraper is doing? I wanted to  
try different XPath queries but felt like was working blind- ended up  
with blank or with various Scalar() values - which I assume means the  
xpath expression matched too many things.

You can see a sample wishlist here: http://www.amazon.com/gp/registry/wishlist/AIOY8FQZ99E9

To see the format - basically I'm grabbing each tbody that has a name  
attribute, and can get the title and url, but can't seem to match the  
image.

Thanks in advance for any guidance-

John
