Pinboard tags parsed as a single tag

[therourke]

I have finally turned my back on delicious. It is just not reliable anymore. I want to use Diigo, but the feed does not parse tags properly. I have turned to pinboard.in, but tags are parsed as one single tag. They therefore come out like this: http://i.imgur.com/5kPBAmP.jpg

Is there any way to solve this in the pre db section of the plugin?

The feed section with tags looks like this:

<taxo:topics><rdf:Bag>  <rdf:li rdf:resource="http://pinboard.in/u:therourke/t:cinema" />
<rdf:li rdf:resource="http://pinboard.in/u:therourke/t:film" />
<rdf:li rdf:resource="http://pinboard.in/u:therourke/t:horror" />
<rdf:li rdf:resource="http://pinboard.in/u:therourke/t:special" />
<rdf:li rdf:resource="http://pinboard.in/u:therourke/t:effects" />
<rdf:li rdf:resource="http://pinboard.in/u:therourke/t:stream" />
<rdf:li rdf:resource="http://pinboard.in/u:therourke/t:the" />
<rdf:li rdf:resource="http://pinboard.in/u:therourke/t:thing" />
</rdf:Bag></taxo:topics>

I have this section in my plugin, but it doesn't appear to work:

function pre_db($item, $original)
{

        if (isset($item->item_data['topics'])) {
        foreach ($item->item_data['topics'] as $key => $value) {
            $item->item_data['tags'][$key] = $value->term;


        } 
 }

Hope someone can help :-)

So this is because pinboard's RSS uses RSS 1.0's Taxonomy Module to do it's tags. SimplePie (the library used to parse RSS/Atom feeds) does not support the namespace url of: "http://purl.org/rss/1.0/modules/taxonomy/" (see SimplePie Supported XML NameSpaces).

However I was able to get it working by creating a LifePress plugin for pinboard.in using the following code if you'd like to test it out (note it will only fix tags on bookmarks going forward):

/application/plugins/pinboard_in.php

<?php if (!defined('BASEPATH')) exit('No direct script access allowed');

class Pinboard_in {

    function pre_db($item, $original)
    {
        $item->item_data['tags'] = array();

        $topics = $original->get_item_tags('http://purl.org/rss/1.0/modules/taxonomy/', 'topics');

        if ($topics) {
            $bag = $topics[0]['child']['http://www.w3.org/1999/02/22-rdf-syntax-ns#']['Bag'];
            $li = $bag[0]['child']['http://www.w3.org/1999/02/22-rdf-syntax-ns#']['li'];

            foreach ($li as $topic) {
                $resource = $topic['attribs']['http://www.w3.org/1999/02/22-rdf-syntax-ns#']['resource'];
                $item->item_data['tags'][] =  substr($resource, strpos($resource, 't:') + 2);
            }
        }

        return $item;
    }

    function pre_display($item)
    {
        return $item;
    }
}

/* End of file pinboard_in.php */
/* Location: ./application/plugins/pinboard_in.php */
