Parsing XML Responses with convert function? Pinterest and Facebook

[digeridoopoo]

Hi,

I've had some success grabbing XML feed from Pinterest and Facebook, using the following URLS:

http://pinterest.com/travelchanneleu/feed.rss

https://www.facebook.com/feeds/page.php?id=51539791474&format=rss20

I can map the feed to a model, store and view relatively easily. The problem I have is that both responses from the above links contain, for example, images and text inside one part of the response.

My question is, how would I go about splitting up the description part below, in the pinterest description feed I get both the image and text:

<description>&lt;p>&lt;a href="/pin/98868154291824290/">&lt;img src="http://media-cache-ec2.pinterest.com/192x/03/45/5f/03455ff1a62e80f4c0f59c475bf416e6.jpg">&lt;/a>&lt;/p>&lt;p>Airport 24/7 : Miami   If you think you know life in an airport, think again. This is Miami Airport as you've never seen it before.&lt;/p>
</description>

I'm pretty sure I would have to use a convert function on the model. Would I have to do something like Ed Spender did here for his APOD carousel?

 convert: function(value, record) {
                    var content = record.get('content'),
                        regex   = /img src=\"([a-zA-Z0-9\_\.\/\:]*)\"/,
                        match   = content.match(regex),
                        src     = match[1];
 
                    if (src != "" && !src.match(/\.gif$/)) {
                        src = "http://src.sencha.io/screen.width/" + src;
                    }
                    
                    return src;
                }

Any help would be much appreciated.....or any useful resources how to use the convert function on a model! I don't really understand the code above very well.

Thanks,

:-)

Yes, looks like you want to change the value of that field to prefix the io url. You could do it in the convert like you are or in a view.
