我的网站的核心是一个xml文件master.xml。我正试图从中创建提要，一个经典的rss提要和一个播客提要，这意味着XML到XML。
我尝试的第一种方法是用PHP的DomDocument创建一个真正的xml文件，但我遇到了基本问题。即使它工作正常，它仍然会创建一个文件，而不是正在请求的文件。
现在，我已经将podcast.xml更改为podcast.php，并使用项的循环回显xml声明和xml标记。像iTunes这样的阅读器在这方面做得很好。但是浏览器是不会被骗的。
-
Chrome将内容放入伪html文件中，并显示纯文本，忽略xsl-stylesheet。尽管如此，它在代码视图中只显示XML。
-
Firefox显示它像一个真正的xml文件，但在代码视图中，它显示关闭红色，好像是一个标记错误(事实并非如此)。
这让我(作为一个有抱负的人)想知道专业人士如何处理动态创建提要的愿望。当然，我不是第一个这样做的人。
我为此创建了一个小的开源库。
你可以在这里下载并学习如何使用它。
