How can I escape double quotes in XML attributes values?
提问by Jader Dias
From the following trials
从以下试验
<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?
只有最后一个适用于我在这里使用的 XML 解析器。有替代方案吗？

From the XML specification:
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 "'"，双引号字符 (") 可以表示为 """。

A double quote character (") canbe escaped as ", but here's the rest of the story...
双引号字符 ( ")可以转义为"，但这是故事的其余部分......
Double quote character mustbe escaped in this context:
在这种情况下必须转义双引号字符：
In XML attributes delimited by double quotes:
<EscapeNeeded name="Pete "Maverick" Mitchell"/>
在由双引号分隔的 XML 属性中：
<EscapeNeeded name="Pete "Maverick" Mitchell"/>
Double quote character need notbe escaped in most contexts:
在大多数情况下，双引号字符不需要转义：
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"/>
在 XML 文本内容中：
<NoEscapeNeeded>He said, "Don't quote me."</NoEscapeNeeded>在由单引号 (
')分隔的 XML 属性中：<NoEscapeNeeded name='Pete "Maverick" Mitchell'/>类似地，
'如果 (") 用于属性值分隔符， ( ) 不需要转义：<NoEscapeNeeded name="Pete 'Maverick' Mitchell"/>

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