Problem sa HTMLDocument.Iterator klasom(IMG tagovi)

^{30.10.2005. u 09:49 - pre 224 meseci}

Imam problem pri upotrebi klase "javax.swing.text.html.HTMLDocument.Iterator".
Prilikom parsiranja html dokumenta za zadati tip taga pozivom metode getIterator(HTML.Tag.naziv_taga) moguce je ocitati sadrzaje tih tagova i vrednosti njihovih atributa.
Medjutim, ako zatrazim IMG tagove , dokument mi ne vraca ni jedan iako u njemu postoje.Da li je neko imao slican problem i kako se moze resiti?

Evo , probajte i sami(pokusajte druge tagove):

Code:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLConnection;
import java.util.StringTokenizer;
import java.util.Vector;

import javax.swing.text.AttributeSet;
import javax.swing.text.BadLocationException;
import javax.swing.text.html.HTML;
import javax.swing.text.html.HTMLDocument;
import javax.swing.text.html.HTMLEditorKit;
import javax.swing.text.html.parser.ParserDelegator;

public class DocumentIteratorExample
{

    DocumentIteratorExample(String tt) throws BadLocationException, IOException
    {



        URL url = new URL(tt);
        URLConnection connection = url.openConnection();
        InputStream is = connection.getInputStream();
        InputStreamReader isr = new InputStreamReader(is);
        BufferedReader br = new BufferedReader(isr);
        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);

        for (HTMLDocument.Iterator iterator = htmlDoc.getIterator(HTML.Tag.IMG); iterator.isValid(); iterator.next())
        {

              System.out.println("Img found");

        }

        System.out.println("Finished");



    }
public static void main(String args[]) throws Exception
{
    DocumentIteratorExample doc = new DocumentIteratorExample("http://www.b92.net");
}
}
