我有一个包含音频文件字段的内容类型“音频”。该字段接受多个值，因此每个节点可以包含任意数量的音频文件。通常，当您构建一个 RSS 提要视图时，它会为每个节点生成一个<item>，每个节点都有多个<enclosure>条目，每个音频文件一个。<item>但出于我的目的，我需要视图为每个音频文件值单独输出。因此，例如，如果选定节点中有 3 个音频文件，则整个节点将在提要中重复 3 次，每个节点将仅包含一个音频文件附件。

这样做的原因是，在我的具体情况下，我hook_node_view()在自定义模块中使用将 MRSS 标记添加到视图生成的每个节点。因此，与其将音频文件包装在标签中，不如<enclosure>将它们包装在<media:content>标签中。<media:content>根据 MRSS 规范，每个条目不应超过一个，<item>除非它们代表相同的内容。这是因为其他标签喜欢<title>并<description>属于<media:content>同一个标签中的所有标签<item>。具有讽刺意味的是，自定义钩子是最简单的部分，但首先我需要让视图以我描述的方式输出节点。

那么有什么方法可以使用新的 Drupal 7 视图分组功能或其他方法来生成我正在寻找的输出？我很想知道诀窍！否则，我将不得不使用自定义菜单项并失去使用 Views 获得的所有优势（例如自动缓存和能够在 Views UI 中工作）。

创建“文件”视图，然后在视图 UI 右侧的高级折叠字段集下，创建节点与文件的关系（连接）。

这是一个快速视图，您可以在此处复制并导入您的视图 ui：

<?php
    $view = new view;
    $view->name = 'test';
    $view->description = '';
    $view->tag = 'default';
    $view->base_table = 'file_managed';
    $view->human_name = 'test';
    $view->core = 7;
    $view->api_version = '3.0';
    $view->disabled = FALSE; /* Edit this to true to make a default view disabled initially */

    /* Display: Master */
    $handler = $view->new_display('default', 'Master', 'default');

至于围绕整个 RSS 打印输出的正确标记，您可以操作视图模板。要修改每条记录，请使用 views-view-fields--test.tpl.php（例如）。对于整个视图的包装器，请使用 views-view--test.tpl.php （例如）。可用的模板位于视图 UI 上第三个栏杆（折叠的栏杆）底部的“主题”链接下。只需将视图模板文件放入您的主题文件夹并全部抄送。
