如何在XML属性值中转义双引号?

From the following trials

从以下试验

<tag attr="\"">
<tag attr="<![CDATA["]]>">
<tag attr='"'>

Only the last one works for a XML parser that I'm using here. Is there any other alternative?

我在这里使用的XML解析器只能使用最后一个。还有其他选择吗?

You can use "

您可以使用“

From the XML spec:

从XML规范:

To allow attribute values to contain both single and double quotes, the apostrophe or single-quote character (') may be represented as "'", and the double-quote character (") as """.

为了允许属性值同时包含单引号和双引号，撇号或单引号字符(')可以表示为“&apos”;，双引号字符(")为";"

The String conversion page on the Coder's Toolbox site is handy for encoding more than a small amount of HTML or XML code for inclusion as a value in an XML element.

编码器工具箱站点上的字符串转换页面可以方便地编码少量的HTML或XML代码，以便将其作为XML元素的值包含在其中。

A double quote character (") can be escaped as ", but here's the rest of the story...

一个双重引用的角色(")可以被转义成";但下面是故事的其余部分……

Double quote character must be escaped in this context:

In XML attributes delimited by double quotes:

在用双引号分隔的XML属性中:
```
<EscapeNeeded name="Pete &quot;Maverick&quot; Mitchell"/>
```

Double quote character need not be escaped in most contexts:

In XML textual content:

在XML文本内容:

<NoEscapeNeeded>He said, "Don't quote me."</NoEscapeNeeded>

In XML attributes delimited by single quotes ('):

在用单引号(')分隔的XML属性中:
```
<NoEscapeNeeded name='Pete "Maverick" Mitchell'/>
```
Similarly, (') require no escaping if (") are used for the attribute value delimiters:

类似地，如果属性值分隔符使用(')，则不需要转义:
```
<NoEscapeNeeded name="Pete 'Maverick' Mitchell"/>
```
