Regex在基于wordpress的网站上查找主题信息

Question

我正在尝试构建一个脚本，它将进入任何给定wordpress站点的css文件，并检索主题信息。问题是-当我抓取页面时，所有的换行符都变成了空格，并且顺序总是不同的。例如：

/*
Theme Name: ColorWay
Theme URI: http://www.inkthemes.com/wp-themes/colorway-wp-theme/
Description: Colorway is Simple, Elegant, Responsive and beautiful Theme with Easy Customization Options built by InkThemes.com. The Customization Options includes using your own Logos, Backgrounds, Analytics and your own Custom Footer Texts and Analytics that can be tweaked using Theme Options Panel. Colorway Theme is Single Click Intall feature, Just press activate button and your website will get ready with all the dummy content. Just set the content from the Themes Options Panel. Colorway by InkThemes.com is suitable for any business or personal website. The Theme can work for various different niches. It includes special styles for Gallery pages, and has an optional fullwidth page template as well.
Author: InkThemes.com
Author URI: http://www.inkthemes.com
Version: 2.5.1

License URI: license.txt
Tags: black, blue, green, white, gray, custom-menu, dark, two-columns, fixed-width, custom-header, custom-background, threaded-comments, sticky-post, custom-colors, custom-header, custom-menu, light, theme-options, editor-style
*/

这可能很简单，但是在抓取之后，我得到了以下结果：

/* Theme Name: ColorWay Theme URI: www.inkthemes. com/wp-themes/colorway-wp-theme/ Description: Colorway is Simple, Elegant, Responsive and beautiful Theme with Easy Customization Options built by InkThemes.com.

只有一段文字。你会怎么做呢？

编辑：

这是一个在代码不在一行的情况下可以工作的示例：

对不起，我以为你指的是我想刮掉的URL。

下面是一个在源代码上工作的示例，如果我只复制它：

$html = file_get_html('http://website-addons.net/wp-content/themes/powermag/style.css?ver=all');
          preg_match("/Theme\sName:\s?(.+)/", $html, $themename);
          preg_match("/Theme\sURI:\s?(.+?)\s/", $html, $uri);
          preg_match("/Version:(\s?.+?)\s/", $html, $version);
          preg_match("/Description:(.+)\s/", $html, $desc);
          preg_match("/Author:(.+?)\s/", $html, $author);
      echo $themename[1];

现在这样做是行不通的。我只会得到一大堆代码。

当然，我想单行和多行都可以。
