| how to extend HTML tags/attributes? [message #217885] |

Hi,
Is there a convenient way of extending HTML tags/attributes?
Writing something like:
<div myCustomTag="...">
is not accepted by HTML validator.
Is there a way to "improve" HTML validator?
Thanks!

I use custom attributes within HTML tags. Yes the validator complains,
but the browser simply ignores it.
Maybe a project level setting?
div : myCustomTag
etc?

For XHTML I agree, but HTML is looser and does "allow" it.

The browsers may allow it, but that doesn't make it valid.
In any case, we do have an _internal_ extension point,
org.eclipse.wst.xml.core.modelQueryExtensions, making use of
subclasses of
org.eclipse.wst.xml.core.internal.contentmodel.modelquery.ex tension.ModelQueryExtension
that could be used to add new definitions for what's valid. This
makes use of a number of _internal_ interfaces, however, and is
unsupported beyond its use in WTP, so you'd be on your own. And be
aware that it's easy to torpedo editor performance by misusing it.

Which is unfortunate as it can be useful. I use it inside a <span> to
mark text for special processing. Well, two custom attributes.
The user selects some text in a JavaScript text editor (Xinha), then
clicks on a button. The button surrounds the selected text with a
<span> which contains a custom attribute.
On the server side I parse for the span/attributes, then do the
processing on the text. I then save the original and the processed text
into a DB.
When showing the two texts, the text inside the <span> is in a
different CSS class. So the user can see the selected text plus what
the processing did.
Um, somewhat terse, but I have an NDA...
The alternative would be to subvert and mis-use some standard
attributes.

There is more there than just UI. The text between the <span> and
</span> is replaced.
