如何从Zend_Feed_Rss通道对象获取实际的LINK url属性

Question

我试图了解如何使用Zend_Feed_Rss。根据{{​​3}}，要获取频道的链接，您可以使用$ channel-＆gt; link（）方法访问该频道。但是当我这样做时，我得到一个数组，并且我想要的实际内容的链接被隐藏在数组的SECOND项中。我究竟做错了什么？文档不是很有用;似乎它希望你只是神奇地弄清楚如何使用这种特殊的方法。此外，我尝试使用谷歌搜索其他资源但无济于事，所以我真的需要一些帮助。

这是我最终获得的数组：

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
        (

            [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] => 
        )

  ...
