解析XML时出错：对实体“版本”的引用必须以';'结尾分隔符 [英] Error parsing XML : The reference to entity "version" must end with the ';' delimiter

问题描述

我对此很新，很抱歉，如果这是一个简单的问题。

I'm fairly new to this, so sorry if this is a simple question.

我正在尝试在我的网站上安装FB like box www.thehungryeurasian.com

I'm trying to install the FB like box onto my website www.thehungryeurasian.com

但是，当我尝试插入Javascript SDK时：

However, when I try inserting the Javascript SDK:

<div id="fb-root"></div>
<script>(function(d, s, id) {
  var js, fjs = d.getElementsByTagName(s)[0];
  if (d.getElementById(id)) return;
  js = d.createElement(s); js.id = id;
  js.src = "//connect.facebook.net/en_US/sdk.js#xfbml=1&version=v2.0";
  fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>

出现以下错误：

Error parsing XML, line 884, column 64:
The reference to entity "version" must end with the ';' delimiter.

推荐答案

看起来有些事情是将您的文档解释为XML而不是比HTML。 XML比HTML更严格 - 其中一条规则是&符号（& ）具有特殊含义。它们的意思是这里有一个XML实体，这是一个特殊的角色。例如，您可以输入& quot; 来插入或& gt ; 将>插入到您的文档中。

It looks like something is interpreting your document as XML rather than HTML. XML is much stricter than HTML - one of the rules is that ampersands (&) have a special meaning. They mean "here comes an XML entity", which is a special character. For instance, you can type " to insert ", or > to insert > into your document.

在这种情况下，您的代码正在解释& version 在第6行作为其中一个实体的开头。如果您按如下方式更新第6行：

In this case, your code is interpreting &version on line 6 as the start of one of these entities. If you update line 6 as follows:

js.src = "//connect.facebook.net/en_US/sdk.js#xfbml=1&version=v2.0";

然后你会发现错误消失了。

Then you should find that error disappears.
