Add additional information from external RSS feed

[shairyar]

Hi @eko,

I am trying to use this bundle for jobboard where the bundle will be setup to fetch jobs based on rss. At present I can see and persist the following information to the database

- feed_item_title
- feed_item_description
- feed_item_link
- feed_item_pub_date

But I need more information like, city, country, etc.. (the rss feeds we will be fetching provide this information) so I have few questions

1. Do I need to create custom hydrator?
2. It is my understanding that inside the hydrator I should be able to access the details i need (city, state and country), if this is true then how do I access it?

For example inside DefaultHydrator I can see that you are doing the following
$entity->setFeedItemTitle($entry->getTitle());

How do you know that you have access to $entry->getTitle() because when I var_dump $entry all i see is as following

I do not see any object here that gives access to title, content or link and so on.

So a bottom line is how do I see what all elements I have that I can pass to my Entity?

I hope my question is clear :)
