#205 Problem with \" in meta tags

[jdc185s]

I have a meta tag such as:
<meta name="description" content="This is test data
\" and more test.\" ha"/>

When calling MetaTag.getMetaContent() only 'This is
test data\\' is being returned. Notice, the \"
becomes \\", which is causing the problem.

Originally this looked like a problem with the lexer
handling attribute values. I even wrote a test case to
replicate it:

/**
* Bug #1465471 Problem with \" in meta tags
* @throws ParserException
*/
public void testEscapedQuoteInContent () throws
ParserException
{

String content = "This is test data \\\" and more
test.\\\" ha";
createParser(
"<meta name=\"description\" content=\"" +
content + "\"/>"
);
parseAndAssertNodeCount (1);
assertType ("meta tag", MetaTag.class, node[0]);
MetaTag metaTag = (MetaTag)node[0];
assertStringEquals(
"meta content",
content,
metaTag.getMetaContent ()
);
}

However, the escaping of double quotes with a back-slash is
not valid HTML. If double quotes are to be included in a
value, either of the character entities &#34; or &quot; can
be used, see:
http://www.w3.org/TR/html4/intro/sgmltut.html#h-3.2.2

The value of the content attribute for the META tag is
CDATA, described by:
http://www.w3.org/TR/html4/types.html#type-cdata
which has additional constraints on the interpretation of
values, but does not alter the handling of quotes.

This is rejected, unless the submitter would like to raise a
RFE to handle bogus attribute values.
