雅虎管道我如何对换标题和描述

Question

我正在使用雅虎管道创建RSS源，但我想在标题描述和标题描述中使用标题。我想交换标题和说明。

<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

这里是你可以做一个办法 - 用3个模块交换标题和描述字段：

1. 获取传递：拉RSS提要。我使用Yahoo Finance feed作为示例。
2. 重命名：请item.title的副本newDesc，并item.description作为newTitle的
3. 创建RSS：设置标题newTitle的描述newDesc，其他为默认值

我创建了一个样本管你可以查看和复制：http://pipes.yahoo.com/pipes/pipe.info?_id=ffc846056c71a4dd3df7b01d16fdd613

下面是从原来的Yahoo Finance RSS feed样本：

<item>

...和h ERE是从样品管输出相应的，标题为&描述交换：

<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> 
    <description>Samsung Posts $7.4B Profit as Handsets Mask Weak Chip Sales</description>

    </item> 

注：在我的样本上述事情发生的pubdate的。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除。
