如何从 JSON 中删除 HTML 实体？

Question

我正在基于this JSON data 创建a simple RSS feed app using AngularJS。

我设法获得了title 和content 的帖子。

但是，我在处理content 数据时遇到了问题。我想去掉里面的所有 HTML 实体，让它看起来像这样的 Pocket 应用程序：

我只想：

1. 纯文本内容（与提要源的段落结构相同）
2. 居中对齐的图片
3. 超链接
4. 无序列表和有序列表项
5. 视频（embed 标签的结果 - 如果有）

我阅读了有关 ngSanitize 的信息，但我无法真正理解如何使用它来实现我想要的。

怎么做？

如果您想从 Json 内容中完全删除 html 标签... 然后检查这个..从您的示例 Json 中获取的数据..

输入：

var json = {
    "content": "<p>One of the many new features in <a title=\"WordPress 3.5\" href=\"http://codex.wordpress.org/Version_3.5\">WordPress 3.5</a> is the Iris color picker. <a title=\"Replace Farbtastic color picker\" href=\"http://core.trac.wordpress.org/ticket/21206\"> Iris replaces the, now deprecated, Farbtastic</a> color picker script.  The new Iris color picker is shown off in the Theme Customizer for the Twenty-Twelve theme.</p>\n<p><img class=\"aligncenter size-full wp-image-1634\" src=\"http://rachelbaker.me/wp-content/uploads/2012/11/WordPress-theme-customizer-color-picker2.png\" alt=\"\" /></p>\n<p>As soon as I saw Iris, I fell in love. She is user-friendly, colorful and fun. I found that implementing the new color picker is <a title=\"Adding Farbtastic to WordPress Widgets\" href=\"http://pippinsplugins.com/adding-the-farbtastic-color-picker-to-your-wordpress-widgets/\">very similar to Farbtastic</a>.</p>\n<h3>Iris Color Picker Demo Plugin</h3>\n<p>To use the Iris color picker in a plugin requires:</p>\n<ol>\n<li>Running a version of WordPress that is 3.5 Beta or higher.</li>\n<li>Loading the &#8216;wp-color-picker&#8217; script and style into your plugin options page.</li>\n<li>Adding a text input for your color value to your plugin options page.</li>\n<li>Writing a custom jQuery script to call Iris&#8217;s wpColorPicker method on your color text input field(s).</li>\n</ol>\n<p><strong>How does the code look for implementing steps 2-4?</strong><br />\nI created a demonstration plugin to help answer that. The plugin doesn&#8217;t do anything itself, it is only intended as a guide for developers interested in using the new Iris color picker in a WordPress plugin.</p>\n<p><a class=\"button\" href=\"https://github.com/rachelbaker/iris-color-picker-demo\">View on Github</a></p>\n<p><img class=\"aligncenter size-full wp-image-1635\" src=\"http://rachelbaker.me/wp-content/uploads/2012/11/screenshot-iris-color-picker-demo.jpeg\" alt=\"Iris Color Picker Demo Plugin\" /></p>\n"
};
var someString = 
json.content.replace(/<\/?([a-z][a-z0-9]*)\b[^>]*>/gi, '').
replace(/&#[0-9]+;t/gi,"").replace(/\[/g,"").replace(/\]/g,""); 


console.log(someString);
