推荐答案

Youtube让您每个请求最多获取50个条目.
响应包含一些<link>元素.并且如果还有更多记录要提取，则其中一个记录的格式为<link rel='next' ...例如

Youtube let's you fetch up to 50 entries per request.
The response contains some <link> elements. And if there are still more records to fetch one of it is of the form <link rel='next' ... e.g.

<link
  rel='next'
  type='application/atom+xml'
  href='https://gdata.youtube.com/feeds/api/playlists/plalistID?start-index=26&amp;max-results=25&amp;v=2'
/>

搜索此元素，并获取href属性指向的文档，直到响应中没有<link rel='next'元素.

Search for this element and retrieve the document that the href attribute points to until the repsonse has no <link rel='next' element.
