雅虎管道我如何對換標題和描述

Question

我正在使用雅虎管道創建RSS源，但我想在標題描述和標題描述中使用標題。我想交換標題和說明。

<item> 
<title>"**title**"</title> 
<description>"**description**"</description> 
<link>http://link</link> 
</item> 

我想

<item> 
<title>"**description**"</title> 
<description>"**title**"</description> 
<link>http://link</link> 
</item> 

Answer 1

這裏是你可以做一個辦法 - 用3個模塊交換標題和描述字段：

1. 獲取傳遞：拉RSS提要。我使用Yahoo Finance feed作爲示例。
2. 重命名：請item.title的副本newDesc，並item.description作爲newTitle的
3. 創建RSS：設置標題newTitle的描述newDesc，其他爲默認值

我創建了一個樣本管你可以查看和複製：http://pipes.yahoo.com/pipes/pipe.info?_id=ffc846056c71a4dd3df7b01d16fdd613

下面是從原來的Yahoo Finance RSS feed樣本：

...和h ERE是從樣品管輸出相應的，標題爲&描述交換：

<item>

    <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>

    </item> 

注：在我的樣本上述事情發生的pubdate的。我認爲這可能是雅虎管道緩存問題，將在下次管道運行時清除。
