FeedsHTTPFetcher: how to parse object to get source url? I've got several content-types based on imported RSS feeds (Feeds import, Simple Pie library).

In a Views pre render, I try to display an information stored in $row-&gt;node_feeds_item__feeds_source_config that looks like this:

a:1:{s:16:"FeedsHTTPFetcher";a:1:{s:6:"source";s:38:"http://www.as-e.be/agendas_rss/rss.xml";}}


How can I just get the http://www.as-e.be/agendas_rss/rss.xml part of that object? I have no idea how to parse that.
Ok, I found out a dirty solution to extract an URL from a random string text!

preg_match('#\bhttps?://[^\s()&lt;&gt;]+(?:\([\w\d]+\)|([^[:punct:]\s]|/))#', $row-&gt;node_feeds_item__feeds_source_config, $match);
