使用PHP动态创建XML文件（一般策略）

我网站的核心是一个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的转换

我尝试的第一种方法是使用PHP的DomDocument创建一个真正的XML文件，但我遇到了一些基本问题。即使它工作正常，它仍然会创建一个不是所请求文件的文件

现在，我已经将podcast.xml更改为podcast.php，并使用一个项目循环来响应xml声明和xml标记。像iTunes这样的读者可以很好地理解这一点。但是浏览器不能真的被愚弄

Chrome将内容放入伪HTML文件并显示纯文本，忽略xsl样式表。尽管如此，它在codeview中只显示XML

Firefox将其显示为一个真实的XML文件，但在codeview中，它以红色显示结束，就好像是一个标记错误（事实并非如此）

这让我（作为一个有抱负的个人）想知道专业人士是如何处理动态创建提要的愿望的。当然，我不是第一个尝试这个的人。

我已经为此创建了一个小型开源库

您可以下载并学习如何使用它

下面是一个例子：

use iTunesPodcastFeed\Channel;
use iTunesPodcastFeed\FeedGenerator;
use iTunesPodcastFeed\Item;

require __DIR__ . '/vendor/autoload.php';

// SETUP CHANNEL
$title = 'Read2Me Daily Curated Articles';

DOM是一种有效且良好的方法（另一种方法是XMLWriter）。您应该描述DOM的问题。chrome中的XML视图已被破坏，即使它是具有正确内容类型的有效XML，也会显示为HTML。DOM方法会导致XMP组合。我曾经体验过Chrome的行为很奇怪，但它是一种流行的浏览器，我希望人们能够将提要视为一个样式化的页面（使用xsl和css）。您应该描述DOM的问题。chrome中的XML视图已被破坏，即使它是具有正确内容类型的有效XML，也会显示为HTML。DOM方法会导致XMP组合。我曾经体验过Chrome的行为很奇怪，但它是一款流行的浏览器，我希望人们能够将提要视为一个样式化的页面（使用xsl和css）。
