Answer 1

以下是一种方法 - 使用3管道模块交换标题和说明字段：

获取Feed：拉入RSS Feed。我使用Yahoo Finance feed作为样本。
重命名：将item.title复制为newDesc，将item.description复制为newTitle
创建RSS：将标题设置为newTitle，将描述设置为newDesc，将其他设置为默认值

我创建了一个可以查看和复制的示例管道：http://pipes.yahoo.com/pipes/pipe.info?_id=ffc846056c71a4dd3df7b01d16fdd613

以下是原始Yahoo Finance RSS feed的示例：

<item>
    <title>Samsung Posts $7.4B Profit as Handsets Mask Weak Chip Sales</title>
    <link>http://us.rd.yahoo.com/finance/news/rss/story/SIG=149kpevtc/*http%3A//us.rd.yahoo.com/finance/news/topfinstories/SIG=126hhlj6u/*http%3A//finance.yahoo.com/news/samsung-posts-7-4-bln-234859667.html?l=1</link>
    <description>Samsung Electronics Co., the world's top technology firm by revenue, reported record quarterly profit of $7.4 billion on Friday, with strong sales of its Galaxy range of phones masking sharply lower memory chip sales.</description>

...这里是样本管道的相应输出，标题为＆amp;描述交换：

<item>
     <title>Samsung Electronics Co., the world's top technology firm by revenue, reported record quarterly profit of $7.4 billion on Friday, with strong sales of its Galaxy range of phones masking sharply lower memory chip sales.</title>
     <link>http://us.rd.yahoo.com/finance/news/rss/story/SIG=149kpevtc/*http%3A//us.rd.yahoo.com/finance/news/topfinstories/SIG=126hhlj6u/*http%3A//finance.yahoo.com/news/samsung-posts-7-4-bln-234859667.html?l=1</link>
     <description>Samsung Posts $7.4B Profit as Handsets Mask Weak Chip Sales</description>

  </item>

注意：在上面的示例中，pubDate发生了一些事情。我认为这可能是雅虎管道缓存问题，将在下次管道运行时清理。
