Heres what I tried...
In Main html page....
<iframe src="./example.html" id="frame" frameborder="1"></iframe>
and example.html looks like this..
<!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">
<head>
<title>Example</title>
</head>
<body>
<p>YOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO</p>
</body>
This results in empty iframe.
--UPDATE--
Ok,the problem was that simply refreshing the page did not update the iframe. but when I clsed it and reopened it it was fine. Can someone explain this? Do iframes need to be refreshed?
Example.html should be:
<!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">
<head>
<title>Example</title>
</head>
<body>
<p>YOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO</p>
</body>
</html>
Also make sure your path to example.html is correct in your iframe, as well as having a set height & width.

Can someone explain me why I'm not allowed to use the <meta>-tag?
I always use it to ensure utf-8 encoding.
My code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
<head>
<meta charset="utf-8">
My IDE (PHPStorm) throws the following message:
Element meta is not allowed here
Put the meta tag inside the head, the only children of the HTML element should be head and body.
Try this:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
<head>
<meta charset="utf-8">
</head>
</html>
The CSS active link property is not working in ASP.net.
When i comment the Doctype, it starts working fine. Following is the Doctype:
<DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
I found many doctypes but the other CSS stops working when I change.
Is there any way to use active link property with this doctype?
This is the HTML and CSS code
<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">
<head>
<style type="text/css">
a:active
{
background-color:Red;
}
</style>
</head>
<body>
w3schools.com
wikipedia.org
</body>
</html>
I would recommend using the HTML 5 doctype, <!doctype html>.
If you choose to stick with the one you're currently using, do it this way:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
Please notice the ! at the beginning. You need those. :)
I am trying to troubleshoot some issues on a website that is going live today and I keep getting this funny error in Firebug and on the W3C validation site
Here is my DOCTYPE code
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
Here is the error I get:
syntax error
[Break On This Error] < !DOCTYPE html PUBLIC "-//W3C//DTD XHT.../xhtml1/DTD/xhtml1-transitional.dtd">
Any guidance on this seemingly simple task would be appreciated.
Thanks.
Seems you have the same problem here:
http://blog.ryanrampersad.com/2008/09/06/syntax-error-break-on-this-error-doctype-html-public-w3cdtd-xhtml3orgtr-xhtml1-dtd-xhtml1-strictdtd/
check your script tags!
the following gives the same result:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
<script type="text/javascript" src=""></script>
</head>
<body>
</body>
</html>
I am trying to validate the following code with the W3C validator:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-frameset.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
<head>
<title>Test</title>
</head>
<body>
</body>
</html>
I get two errors:
Document type does not allow element "body" here
End tag for "html" which is not finished
Does anyone know how to fix this?
You're using the Frameset DTD, which doesn't allow body. It is meant for use with framesets, which are used to display frames. You can use Strict instead:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
<head>
<title>Test</title>
</head>
<body>
</body>
</html>
I have a XHTML document and want to embed XUL widgets into the document. What is the correct XML syntax to do so?
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
</head>
<body>
insert XUL here
</body>
</html>
add xmlns:xul="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul" to your <html> tag.
then use <xul:element>, e.g. <xul:vbox>
Edit
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:xul="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"
xml:lang="en" lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
</head>
<body>
<xul:vbox>
</xul:vbox>
</body>
</html>
Also, I assume this isn't such a simple case... otherwise there wouldn't be much point in wrapping the xul in html (though the other way around does happen sometimes)
Edit
Some additional points to keep in mind when doing this:
must be served with a valid xml type. e.g. application/xml or text/xml -- not text/html. (See https://bugzilla.mozilla.org/show_bug.cgi?id=101147#c12 -- the whole thread is worth a read)
must be valid xml. A certain degree of sloppiness is tolerated by browsers when parsing html (unclosed tags, etc.) and this is not that case for a document containing xul (even the html parts of the document)
(thanks to Nikolay for the first point)
