Firefox renders the actual data inside the CDATA because it misinterprets the characters "]" "]" and ">" in the CDATA as end tags even though they don't appear continuously as "]]>"
In the following example the CDATA has the characters "]" and ">" before the actual ending tag "]]>".
<html xmlns="http://www.w3.org/1999/xhtml" lang="it">
<head>
<title>Hello World</title>
</head>
<body>
<h1>Hello World Example</h1>
<![CDATA[
[test][test]
<h1>This text should note be displayed</h1>]]>
</body>
</html>
Reproducible: Always
Steps to Reproduce:
1.Copy the example html code given in the details section
2.Open it in the Firefox browser
Actual Results:
Firefox displays the text in the CDATA "This text should note be displayed]]>"
Expected Results:
The text in the CDATA section shouldn't be displayed

The text within the CDATA should be displayed as text. I see the header line followed by the text:
"[test][test]<h1>This text should note be displayed</h1>"
displayed, which looks correct to me.
Is this not what you are seeing?
In the browser I see only the following
"Hello World Example
This text should not be displayed]]>"
If I remove "[test][test]" from CDATA, then the browser just displays "Hello World Example"

This WFM in both these cases:
a) When served as XHTML - "[test][test]<h1>This text should note be displayed</h1>"
b) Using the HTML5 parser - "This text should note be displayed]]>"
When served as text/html, with the current parser, I see the two results mentioned above.

AFAICT this is intentional; As text/html doesn't support CDATA sections the suppressed section is "<![...]...>" - ie the first ">" after the "]" to cover things like <![endif]-->
Probably => invalid
Summary: CDATA closing tag is assumed even though "]]>" is not continious as a string. → CDATA closing tag is assumed even though "]]>" is not continuous as a string.
I think I have over simplified the previous example code. The following code is better form of how we use. Save the following code as HTML and open in the browser.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="it">
<head>
<title>Hello World</title>
</head>
<body>
<h1>Hello World Example</h1>
</body>
<xml style="display:none">
<![CDATA[]></>This text should not be displayed]]>
</xml>
</html>
In our usage we embed a whole XML document in the CDATA section but for simplicity and to reproduce the issue the we have added few characters “]></>” in the CDATA section and made the browser to display “This text should not be displayed]]>”.
We believe that the HTML parser is misinterpreting some of the characters in the CDATA section as end tags and displays the remaining text in the CDATA.
Note: If we save the above code as XHTML, the Firefox browser renders correctly.
We have tested the same with Safari 3 and IE 7, both render correctly.
Hi All,
Has anybody reproduced the issue ? Any response would be appreciated.

I can't help with the issue itself but
>Save the following code as HTML
Why do you don't attach it as html file (add an attachment) ?

The HTML5 parser doesn't close the <xml> element early.
