validating HTML5 documents in oXygen 14.2

Hi all,

in the current HTML5 specification, there is an example of a very simple HTML5 document at http://www.w3.org/TR/html5/single-page. ... ml-element.

Code: Select all

<!DOCTYPE html>
<html lang="en">
<head>
<title>Swapping Songs</title>
</head>
<body>
<h1>Swapping Songs</h1>
<p>Tonight I swapped some of the songs I wrote with some friends, who
gave me some of the songs they wrote. I love sharing my music.</p>
</body>
</html>
From reading this thread: http://www.oxygenxml.com/forum/topic7698.html, I thought a basic HTML5 document would be marked as valid. The error message I get is

Code: Select all

System ID: C:\temp\test.html
Main validation file: C:\temp\test.html
Schema: C:\Program Files\Oxygen XML Editor 14\frameworks\xhtml\xhtml5 (epub3)\epub-xhtml-30.nvdl
Engine name: Jing
Severity: error
Description: elements from namespace "" are not allowed
Start location: 2:17
If I add some empty elements such as link, those are also flagged since they don't have end tags. But for this purpose, I want to use the HTML5 syntax if at all possible, not the XHTML syntax. How do I get this to work?

thanks,

Lauren

Hi Lauren,

Oxygen can only be used to edit wellformed XHTML content which also declares the XHTML namespace.
So your example would also need to declare the XHTML namespace on the <html> element like:

Code: Select all

<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Swapping Songs</title>
</head>
<body>
<h1>Swapping Songs</h1>
<p>Tonight I swapped some of the songs I wrote with some friends, who gave me some of the songs
they wrote. I love sharing my music.</p>
</body>
</html>
Empty elements like <link> can be added to the XHTML content like this:

Code: Select all

    <link href="test.css" rel="" />
Regards,
Radu

Thanks Radu. It sounds like documents written according to the polyglot spec http://www.w3.org/TR/html-polyglot/ should validate, but the full validation according to that specification is not checked (since, for example, xml:base is not allowed in polyglot documents). I can work with that.
