Just bought this today and not sure it's doing what I need.
I'm creating a custom feed calling a photo album on SmugMug (RSS2.0 feed) and the structure is as follows (header section and one item):

<rss version="2.0" xmlns:geo="http://www.w3.org/2003/01/geo/wgs84_pos#" xmlns:exif="http://www.exif.org/specifications.html" xmlns:media="http://search.yahoo.com/mrss/" xmlns:atom="http://www.w3.org/2005/Atom">

I can only access the node for a thumbnail (GUID). What I want is to access one of the nodes in <media:group><media:content> but can't seem to do it. Is there a way to see ALL the nodes returned in feed genie or am I stuck with the preset ones already there?

Hello John,

Seems that your feed is not correctly generated test the link of the feed in FireFox or Chrome.

Regards.

Well, it is correctly generated, I only showed a snippet. When I open it in a browser (Chrome,Safari) it opens in Google Reader and displays each image and name. It is complex and nested, and I don't know how to navigate its structure down to the level to get the correct image. I thought this extension would help me do that.

On another note, I thought I would also be able to use this extension to grab photos from Facebook but it seems I can only get user postings?

Hello John,

then provide me whit the exact link you are using to get the feed.

Regards.

Here you go:

Hello John,

feed genie displays what is returned by the feed. In your case, for example the "description" returns:

<a href="http://jacko.smugmug.com">JackO</a> </p><p><a href="http://jacko.smugmug.com/Vacation/New-Hampshire-Fall-2012/25894606_JGq5Bt#!i=2145938499&k=Xh5nHT4" title="JackO's photo"><img src="http://jacko.smugmug.com/Vacation/New-Hampshire-Fall-2012/i-Xh5nHT4/0/Th/DSC_3826-Th.jpg" width="150" height="150" alt="JackO's photo" title="JackO's photo" style="border: 1px solid #000000;" /></a>

The title and link attributes are also working fine.

The reason I'm using this feed is to grab images for a gallery on a website. With that in mind, what I need, aside from title and description, are all the images in the gallery of a specific size. In the feed, for each photo you get the following list of images by size:

<media:group>
        <media:content url="http://jacko.smugmug.com/Vacation/New-Hampshire-Fall-2012/i-5JkzckR/0/Ti/DSC_3797-Ti.jpg" fileSize="12135" type="image/jpeg" medium="image" width="100" height="100">

        </media:content>
      </media:group>

I would want to grab the 5th image because that's the size needed for my gallery:

<media:content url="http://jacko.smugmug.com/Vacation/New-Hampshire-Fall-2012/i-5JkzckR/0/L/DSC_3797-L.jpg" fileSize="140401" type="image/jpeg" medium="image" width="402" height="600">
          <media:hash algo="md5">b7873a617ac740ff50e1018bbea24e8f</media:hash>
        </media:content>

If I was given an array of the image sizes, so be it, I'll just loop through the array and take the one I want. But I can't seem to figure out how to access that from what's returned by Feed Genie. In fact, I tried to do this on my own first but since I'm not a superstar coder I came to you guys thinking this would solve my problem. Am I wrong?

Hello,

Unfortunately the result you are trying to achieve is not possible using a feed constructed that way.
