we use htmlparser for this kind of job

you can parse and modify nodes with this untested snipplet:

NodeVisitor visitor = new NodeVisitor() {
    public void visitTag(Tag tag) {
            tag.removeAttribute("id");
            tag.removeAttribute("style");
    }

};

Parser parser = new Parser(...);
parser.visitAllNodesWith(visitor);

This little snippet will do the trick.

Ask me if you need some questions about the Regex


public class test {

    public static void main(String[] args) {
        String htmlFragment ="<a  id=\"nav-askquestion\" style=\"cursor:default\" href=\"/questions\">";
        String attributesToRemove = "id|style";

        System.out.println(htmlFragment);
        System.out.println(cleanHtmlFragment(htmlFragment, attributesToRemove));
    }

    private static String cleanHtmlFragment(String htmlFragment, String attributesToRemove) {
        return htmlFragment.replaceAll("\\s+(?:" + attributesToRemove + ")\\s*=\\s*\"[^\"]*\"","");    
    }
}

People might suggest to use regex, but beware, you can use an XML Parser.
