javascript - 如何从 RSS 源中删除 HTML 标签？

Question

我正在使用Google Feed API从 tumblr feed 中提取博客条目.

我已经能够提取内容，但输出带有 html 标签，如下所示:

<p>I remember one day asking one of my mentors James if he ever got nervous around people. James replied, “Only when I need something from them.”</p>

代码很简单，如下:

<script type="text/javascript" src="https://www.google.com/jsapi"></script>
 <script type="text/javascript">
google.load("feeds", "1");

 function initialize() {
   var feed = new google.feeds.Feed("http://adriennetran.tumblr.com/rss");
   feed.load(function(result) {

     if (!result.error) {
       var container = document.getElementById("feed");

       for (var i = 0; i < result.feed.entries.length; i++) {
         var entry = result.feed.entries[i];
         window.content = document.createTextNode(entry.content);
         container.appendChild(content);
       }
     }
   });
 }


 google.setOnLoadCallback(initialize);

 </script>

我尝试编写一个函数来删除以 < 开头的所有内容像这样:

content_array = content.split(" ");

for (i=0; i < content_array.length; i++){
    if ((content_array[i].split(""))[0] == "<"){
      content_array.splice(i, 1);
    }
}

content2 = content_array.toString();

但我得到了 Uncaught TypeError: undefined is not a function错误，因为 content是 object而不是string因此我无法调用 content.split(" ") .

我尝试转换为字符串，但这是控制台的输出

typeof(content)
> "object"

c2 = content.toString()
> "[object Text]"

有人对如何操作从 RSS 检索的元素有任何想法吗？

让我们看看

var regExString = /(<([^>]+)>)/ig; //create reg ex and let it loop (g)
contentString = content.textContent // get text from node (no longer an object but string.

contentString = contentString.replace(regExString, "") //find all tags and delete them.
