我正在努力思考如何使用 Zend_Feed_Rss。根据文档，要获取频道的链接，您可以使用 $channel->link() 方法访问它。但是当我这样做时，我得到了一个数组，而我想要的实际东西的链接被埋在数组的第二个项目中。我究竟做错了什么？文档不是很有帮助；似乎它希望您只是神奇地弄清楚如何使用这种特定方法。另外，我试过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)
            [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] => 
        )

  ...
