Question

为了获得有效的XML RSS提要，我需要对包含'＆amp;'的链接进行url编码在查询字符串中。但是，当某人在浏览器中查看RSS源时，链接不会被解码，因此当他们点击链接时，结果页面会被破坏，因为查询字符串参数未被正确读取。

E.g。

http://www.mysite.com?foo1=bar1&foo2=bar2，在浏览器中查看为http://www.mysite.com?foo1=bar1%26foo2=bar2时，参数foo1将被视为bar1％26foo2 = bar2，而不是将水果和饮料分成两个单独的参数。

将我的链接包装在标签中并且不对它们进行编码工作，但是在我的MRSS Feed中，我有一些字段，例如包含标签的字段会破坏XML。

如何正确编码我的链接，以便一切正常？

使用&amp

如果您查看https://stackoverflow.com/feeds/tag/xml，此问题的条目如下所示，并且您在I.E.中查看时，示例链接正常工作。

            &lt;p&gt;In order to have a valid XML RSS feed, I need to url encode my links which contain &#39;&amp;amp;&#39; in the query string.  However, when a person views the RSS feed in a browser, the links are not decoded, so when they click on the link the resulting page is broken because the query string parameters are not being read correctly.&lt;/p&gt;

&lt;p&gt;E.g.&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;http://www.mysite.com?foo1=bar1&amp;amp;foo2=bar2&quot; rel=&quot;nofollow&quot;&gt;http://www.mysite.com?foo1=bar1&amp;amp;foo2=bar2&lt;/a&gt;, when viewed in the browser as &lt;a href=&quot;http://www.mysite.com?foo1=bar1%26foo2=bar2&quot; rel=&quot;nofollow&quot;&gt;http://www.mysite.com?foo1=bar1%26foo2=bar2&lt;/a&gt;, the parameter foo1 is being taken as bar1%26foo2=bar2 instead of splitting fruit and drink into two separate parameters.&lt;/p&gt;

&lt;p&gt;Wrapping my links in  tags and not encoding them work, but then in my MRSS feed I have fields such as  where including a  tag breaks the XML.&lt;/p&gt;

&lt;p&gt;How can I go about correctly encoding my links so that everything works?&lt;/p&gt;
