Hi,

It sounds like a bug.
Please file it with this test code.

Subject: [Htmlparser-user] StackOverflowError when toHtml() is called

Hi

I want to add an attribute to each tag in a html document. I have 
written a nodevisitor to do that and it works. However, for some 
documents, I get a StackOverflowError when I want to output the html 
back. Here is my code.

public class TestHTMLParser
{
    public static void main(String args[]) throws Exception
    {
        Parser p = new Parser("http://lemonde.fr";);

        NodeList nliste = p.parse(null);

        NodeIterator ni = nliste.elements();
        MyNodeVisitor mynv = new MyNodeVisitor();
        while (ni.hasMoreNodes())
        {
            Node n = ni.nextNode();
            if (n instanceof Html)
                n.accept(mynv);
        }

        System.out.println(nliste.toHtml());
    }
}

public class MyNodeVisitor extends NodeVisitor {  
    public MyNodeVisitor() {
        super();
    }
   
    public void visitTag(Tag tag){
        tag.setAttribute("onClick", "return false;");
    }
}

If I don't use the nodevisitor, I don't get the StackOverflowError.

So is it normal (my html tree has become too deep after the attributes 
add) or is there a bug ?

Thanks for help.
