Drupal 7：爲每個節點創建多個<item> s的RSS訂閱源？

Question

我有一個包含音頻文件字段的內容類型「音頻」。該字段接受多個值，因此每個節點可以包含任意數量的音頻文件。通常，當您構建RSS提要視圖時，它將爲每個節點生成一個<item>，並且每個節點都將有多個<enclosure>條目，每個音頻文件一個。但爲了我的目的，我需要視圖爲每個音頻文件值輸出單獨的<item>。因此，例如，如果所選節點中有3個音頻文件，則整個節點將在饋送中重複3次，每個節點只包含一個音頻文件機箱。

原因是在我的具體情況下，我在自定義模塊中使用hook_node_view()將MRSS標記添加到視圖生成的每個節點。因此，而不是由<enclosure>包裝的音頻文件，它們將被封裝在<media:content>標籤中。根據MRSS規範，除非它們表示相同的內容，否則每<item>不應有多於一個<media:content>條目。這是因爲其他標籤如<title>和<description>屬於同一<item>中的所有<media:content>標籤。具有諷刺意味的是，定製鉤子是最簡單的部分，但首先我需要以我描述的方式輸出節點。

那麼有什麼方法可以使用新的Drupal 7視圖分組功能或其他一些方法來生成我正在尋找的輸出？我很想知道這個訣竅！否則，我將不得不使用自定義菜單條目，並失去使用Views獲得的所有優點（例如自動緩存並能夠在Views UI中工作）。

創建「文件」視圖，然後在視圖UI右側的高級摺疊字段集下創建節點與文件的關係（聯接）。

這裏有一個快速瀏覽，你可以在這裏複製並導入到你的意見UI：

至於圍繞整個RSS打印輸出正確的標記，你可以操縱視圖的模板。要修改每條記錄，請使用views-view-fields - test.tpl.php（例如）。對於整個視圖的包裝，請使用views-view-test.tpl.php（例如）。可用的模板位於視圖UI中第三條軌道（摺疊的）底部的「主題」鏈接下。只需將視圖模板文件拖放到主題的文件夾中即可。
