Yes you can do this.
Look at the program MailRipper.java in the com.kizna.html.parserapplications
package. This program will print only the email addresses on a page (which
are also link tags). Its even simpler to simply filter out all the tags
except the link tags.

Try this :
HTMLParser parser = new HTMLParser("http://myurl.com");
HTMLNode node;
for (Enumeration e = parser.elements();e.hasMoreElements();) {
    node = (HTMLNode)e.nextElement();   // Get the next html node
    if (node instanceof HTMLLinkTag) {
        // Yes - this is a web link. Now you can downcast and do what you
want with it
        HTMLLinkTag linkTag = (HTMLLinkTag)node;
        System.out.println("link to "+linkTag.getLink()+", link text =
"+linkTag.getLinkText());
    }
}

This should give you what you want.
