How can I escape double quotes in XML attributes values?

Question

From the following trials

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

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

**`"`** is the answer; [**here's the explanation**](https://stackoverflow.com/a/47534887/290085). — kjhughes, May 13 '18 at 18:31

From the XML specification:

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 """.

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

Double quote character must be escaped in this context:

In XML attributes delimited by double quotes:

<EscapeNeeded name="Pete &quot;Maverick&quot; Mitchell"/>

Double quote character need not be escaped in most contexts:

In XML textual content:

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

In XML attributes delimited by single quotes ('):
```
<NoEscapeNeeded name='Pete "Maverick" Mitchell'/>
```
Similarly, (') require no escaping if (") are used for the attribute value delimiters:
```
<NoEscapeNeeded name="Pete 'Maverick' Mitchell"/>
```
