Thank You. This was my try:

HTMLDocument.BlockElement block = (HTMLDocument.BlockElement)elem;
int start, end;
String	text;

start = block.getStartOffset();
end = block.getEndOffset();

// thes what attributes are set
for(Enumeration e = block.getAttributeNames(); e.hasMoreElements(); )
   System.out.println(e.nextElement());

SimpleAttributeSet	newType = new SimpleAttributeSet();
newType.addAttribute( "name", "h1");
htmlDoc.setParagraphAttributes(start, end-start, newType, false );

This produces the following HTML-Code:

<p name="h1">
	hello world
</p>

And after a second call to my function. The Enumeration contained two 
attributes with the name "name".

Then I have replaced the boolean parameter of setParagraphAttributes. 
The produced HTML-Code was stupid:

<body name="h1">
	hello world
</body>

When I try to create an object of HTMLDocument.BlockElement instead of 
SimpleAttributeSet I get an compiler error "Enclosing class required".

Any ideas?

Martin
