Parsing & handling of <object> and <param> tags

[Floxxx]

Hi all,

I'm working on allowing people to paste certain embedded video code into a wysiwyg / html editor we've built with the help of (amongst others) javax.swing.text.html.HTMLWriter.

I'm facing the following problem here:

When i try to parse the <object><param></param></object> piece, it removes the <param> tags, and incorporates these in the <object> tag. For example:

<object width="300" height="250"><param name="allowscriptaccess" value="always"></param></object>

becomes:

<object width="300" height="250" allowScriptAccess="always"></object>

All param tags get converted into the object tag as String attributes. Problem with this is that the allowScriptAccess attribute is not a valid attribute of the object tag.

Is there any way to prevent this conversion so it will retain the <param> tags?

Thank you in advance.

Everything you need is at least implicit in javax/swing/text/html/HTMLDocument.java

Curiously, its documentation says the PARAM tags are handled by HiddenAction,
but the code actually has them handled by ObjectAction:

tagMap.put(HTML.Tag.PARAM, new ObjectAction());

and ObjectAction does indeed stuff the PARAM values as attributes of the surrounding OBJECT.

The HTMLDocument code suggests subclassing HTMLReader:

To change the structure one
can subclass <code>HTMLReader</code>, and reimplement the method
getReader(int) to return the new reader implementation.

Unfortunately I haven't time today to try this, but it should be straight forward.
I think the subclass just needs to have a constructor like:

public MyHTMLReader (int offset) {
        super(offset, 0, 0, null);
        tagMap.put(HTML.Tag.PARAM, new HiddenAction());
}

or maybe some newly devised TagAction instead of HiddenAction.
