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?

Answer 1

您可以使用"

Answer 2

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 """.

Answer 3

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"/>
