How do I escape ampersands in XML so they are rendered as entities in HTML?
提问by AJM
I have some XML text that I wish to render in an HTML page. This text contains an ampersand, which I want to render in its entity representation: &.
我有一些希望在 HTML 页面中呈现的 XML 文本。此文本包含一个＆符号，我想在其实体表示中呈现：&。
How do I escape this ampersand in the source XML? I tried &, but this is decoded as the actual ampersand character (&), which is invalid in HTML.
如何在源 XML 中转义此与号？我试过了&，但它被解码为实际的 & 字符 ( &)，这在 HTML中是无效的。
So I want to escape it in such a way that it will be rendered as &in the web page that uses the XML output.
所以我想以这样的方式转义它，它会像&在使用 XML 输出的网页中一样呈现。

When your XML contains &, this will result in the text &.
当您的 XML 包含时&，这将导致文本&。
When you use that in HTML, that will be rendered as &.
当您在 HTML 中使用它时，它将呈现为&.

As per §2.4 of the XML 1.0 spec, you should be able to use &.
根据XML 1.0 规范的 §2.4，您应该能够使用&.
I tried & but this isn't allowed.
我试过 & 但这是不允许的。
Are you sure it isn't a different issue? XML explicitly defines this as the way to escape ampersands.
你确定这不是一个不同的问题？XML 明确地将此定义为转义符号的方法。

The &character is itself an escape character in XML so the solution is to concatenate it and a Unicode decimal equivalent for &thus ensuring that there are no XML parsing errors. That is, replace the character &with &.
该&字符本身是 XML 中的转义字符，因此解决方案是将它与 Unicode 十进制等价物连接起来，以&确保没有 XML 解析错误。也就是说，替换字符&用&。

Use CDATAtags:
使用CDATA标签：
<![CDATA[
This is some text with ampersands & other funny characters. >>
]]>

&should work just fine, Wikipedia has a List of predefined entities in XML.
&应该可以正常工作，维基百科有一个XML 格式的预定义实体列表。

In my case I had to change it to %26.
就我而言，我不得不将其更改为%26.
I needed to escape &in a URL. So &did not work out for me.
The urlencodefunction changes &to %26. This way neither XML nor the browser URL mechanism complained about the URL.
我需要&在 URL 中转义。所以&不适合我。将进行urlencode函数更改&到%26。这样一来，无论是 XML 还是浏览器 URL 机制都不会抱怨 URL。

I have tried &, but it didn't work. Based on Wim ten Brink's answer I tried &amp and it worked.
我试过&，但没有用。根据 Wim 10 Brink 的回答，我尝试了 & 并且它奏效了。
One of my fellow developers suggested me to use & and that worked regardless of how many times it may be rendered.
我的一位开发人员建议我使用 & 并且无论渲染多少次都有效。

&is the way to represent an ampersand in most sections of an XML document.
&是在 XML 文档的大多数部分中表示与号的方式。
If you want to have XML displayed within HTML, you need to first create properly encoded XML (which involves changing &to &) and thenuse that to create properly encoded HTML (which involves again changing &to &). That results in:
如果您希望在 HTML 中显示 XML，您需要首先创建正确编码的 XML（涉及更改&为&），然后使用它来创建正确编码的 HTML（这涉及再次更改&为&）。这导致：
&amp;

How about using the unicode \u0026? Works for me in my android XML files. If problems arise, someone let me know.
使用 unicode\u0026怎么样？在我的 android XML 文件中对我有用。如果出现问题，有人告诉我。
