ParserCallback iFrame question.

Question

Hi,
Im using the HTMLEditorKit Parsercallback class. After creating connection with the URL given. I did this.
HTMLEditorKit htmlKit = new HTMLEditorKit();
HTMLDocument htmlDoc = (HTMLDocument) htmlKit.createDefaultDocument();
HTMLEditorKit.Parser parser =new ParserDelegator();
HTMLEditorKit.ParserCallback callback = htmlDoc.getReader(0);
parser.parse(br, callback, true);Does it gives back a well-formed HTML document? The parsercall back is supposed to do something to HTML document and gives me a new HTML document with all the tags properly indented ? Then how do iterate through to get the iframe tag. The HTML.Tag doesnt consist of the iframe element. Only frame and frameset. How do i get the parse to read the iframe element of the HTML doc. Do i handle it during the parsercallback's handlesimpletag()? or during the parsercallback's handlestart and end tags giving that the document is already well formatted either by using Jtidy or its a xhtml document by default.
Most of you will be asking this if you want a more understanding of what im actually trying to do. Im actually trying to parse through the HTML document get all the possible links. Im able to get it easily with the (HTML.Tag.A) but how do i parse iframes and get to the SRC attribute of the element. All i need is how to handle iframes.
Thank you and sorry for the long read.

Hi camickr,
Thank you for explaining it to me more. Hmmmm.. i will try to look into it more and do as what you say to understand the use of pasercallback. Currently im using HtmlIterator.
HTMLDocument.Iterator aIterator = doc.getIterator(HTML.Tag.A);
               while(aIterator.isValid())
                    SimpleAttributeSet sAttribute = (SimpleAttributeSet) aIterator.getAttributes();
                    //get the HREF attribute of the A element
                    String link = (String) sAttribute.getAttribute(HTML.Attribute.HREF);
                    if(link != null)
                         if(link.indexOf("some text") > -1)
                              extractedURL.add(link);
                    aIterator.next();
               }Basically im able to point to all "a" tags in the html and able to access its attributes. If im just able to point to the iframe element, im pretty sure im able to extract the SRC attribute of the iframe.
