Trying to validate: XHTML 1.0 Strict

**jc_gmk** · 05-31-2007, 09:03 AM

I'm trying to validate my document, it is a XHTML 1.0 Strict.

I have used some flash but it won't validate because I can't use <object> within <noscript>

Is there an alternative that will validate?

HTML Code:

<script type="text/javascript">
AC_FL_RunContent( 'codebase','http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0','width','807','height','176','src','content/images/header','quality','high','pluginspage','http://www.macromedia.com/go/getflashplayer','movie','content/images/header' ); //end AC code
</script>

HTML Code:

<noscript>
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" type="application/x-shockwave-flash" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0" width="807" height="176" data="content/images/header.swf">
<param name="movie" value="content/images/header.swf" />
<param name="quality" value="high" />
</object>
</noscript>

You can wrap the <object> in a <div> or other block-level element, I believe. Read the Flash Satay article for a guide on how to do it properly.

You do realise that by using XHTML you're dropping support for IE, right?

I mainly use IE to test my site and I haven't encountered any problems yet.

I've created sites using XHTML 1.0 Transitional before which have worked in all browsers. This is the first site I am creating that uses Strict.

What issues do you think I'll have using this DOCTYPE?

IE doesn't support native XHTML. Please have a look at this article

It is better if you use Firefox for the testing purpose.

This means you've sent it as text/html. This isn't XHTML, it's badly-formed HTML. Just as when you send a PNG with a GIF MIME-type, the browser will attempt to parse it as HTML, not XHTML. The only difference is that in the case of XHTML it's similar enough to HTML that the browser can error-correct it into HTML and get some sense out of it, thus displaying your page "correctly" in most cases. However, don't be fooled: it's not XHTML, and none of the benefits of using XHTML (or, in fact, the benefits of using valid HTML) apply.

The code I have used is:

HTML 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">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Untitled Document</title>
</head>

<body>
</body>
</html>

This was already created for me when making a new page in Dreamweaver v8.

Does this code not make it XHTML then?

Not alone, no. It's not XHTML unless it's served as application/xhtml+xml, no matter what the DOCTYPE says.

Ok thanks.

Do you suggest that I go back to HTML 4.01 Strict then?

**Twey** · 05-31-2007, 03:21 PM

Yes, I do.

I still don't fully understand why it's not XHTML?

Even though when I submit it for validation I get this message?

I used http://validator.w3.org/ to validate
