rss - How to get the actual LINK url property from Zend_Feed_Rss channel object -

i'm trying wrap head around how use zend_feed_rss. according documentation, link of channel, access method $channel->link(). when so, array, , link actual thing want buried in second item of array. doing wrong? documentation not helpful; seems if expects magically figure out how use particular method. also, i've tried googling other resources no avail, need here.

here's array end getting:

array (     [0] => domelement object         (             [tagname] => atom:link             [schematypeinfo] =>              [nodename] => atom:link             [nodevalue] =>              [nodetype] => 1             [parentnode] => (object value omitted)             [childnodes] => (object value omitted)             [firstchild] =>              [lastchild] =>              [previoussibling] => (object value omitted)             [nextsibling] => (object value omitted)             [attributes] => (object value omitted)             [ownerdocument] => (object value omitted)             [namespaceuri] => http://www.w3.org/2005/atom             [prefix] => atom             [localname] => link             [baseuri] => /path/to/application             [textcontent] =>          )      [1] => domelement object         (             [tagname] => link             [schematypeinfo] =>              [nodename] => link             [nodevalue] => http://whatactuallywant.wordpress.com             [nodetype] => 1             [parentnode] => (object value omitted)             [childnodes] => (object value omitted)             [firstchild] => (object value omitted)             [lastchild] => (object value omitted)             [previoussibling] => (object value omitted)             [nextsibling] => (object value omitted)             [attributes] => (object value omitted)             [ownerdocument] => (object value omitted)             [namespaceuri] =>              [prefix] =>              [localname] => link             [baseuri] => /path/to/applicaiton             [textcontent] => http://whatactuallywant.wordpress.com         )      [2] => domelement object         (             [tagname] => atom:link             [schematypeinfo] =>              [nodename] => atom:link             [nodevalue] =>              [nodetype] => 1             [parentnode] => (object value omitted)             [childnodes] => (object value omitted)             [firstchild] =>              [lastchild] =>              [previoussibling] => (object value omitted)             [nextsibling] => (object value omitted)             [attributes] => (object value omitted)             [ownerdocument] => (object value omitted)             [namespaceuri] => http://www.w3.org/2005/atom             [prefix] => atom             [localname] => link             [baseuri] => /path/to/application             [textcontent] =>          )    ...  )
