如何从Zend_Feed_Rss通道对象获取实际的LINK url属性

Question

我正在设法把重点放在如何使用Zend_Feed_Rss上。 根据文档 ，要获取通道的链接，请使用$ channel-> link（）方法对其进行访问。 但是，当我这样做时，我得到了一个数组，指向我想要的实际东西的链接被埋在了数组的第二个项目中。 我究竟做错了什么？ 该文档不是很有帮助； 似乎希望您只是神奇地找出如何使用此特定方法。 另外，我尝试搜索其他资源，但无济于事，因此我在这里确实需要一些帮助。

这是我最终得到的数组：

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)

            [namespaceURI] => http://www.w3.org/2005/Atom
            [prefix] => atom
            [localName] => link
            [baseURI] => /path/to/application
            [textContent] => 
        )

    [1] => DOMElement Object

            [lastChild] => (object value omitted)
            [previousSibling] => (object value omitted)
            [nextSibling] => (object value omitted)
            [attributes] => (object value omitted)
            [ownerDocument] => (object value omitted)
            [namespaceURI] =>

            [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] => 
        )

  ...
