Re: Need Help

Hello AniketP,


I had the same problem but whit the bold and italics tags (<b> and <i>
respectively). Here is my solution for <i> tags:


Create a class for the tag you are interested in, that extends CompositeTag:

public class ItalicTag *extends CompositeTag*{

    private static final String[] mIds = new String[] {*"I"*};  //Change
this as appropriate
    public ItalicTag ()
    {
    }
    public String[] getIds ()
    {
        return (mIds);
    }
    public String[] getEnders ()
    {
        return (mIds);
    }
    public String[] getEndTagEnders ()
    {
        return (new String[0]);
    }
}



//In your main class:

factory = new PrototypicalNodeFactory();   // create a factory
factory.registerTag(new  ItalicTag  ());   //register your new tag


try {

    Parser parser = new Parser (URL);
    parser.setNodeFactory(factory);
    NodeList list;

    NodeFilter tagfilter = new NodeClassFilter(ItalicTag.class);

    list = parser.extractAllNodesThatMatch(tagfilter);

    for (Node node : list.toNodeArray()) {
String texto = *extractText*(node);      // In this function we will
extract the content between tags (<i> </i>)
           }
} catch (ParserException ex) {
   //do something
}



//the extactText method :

 /**
     *Gets the text that is enclosed between labels. In order to do that
     *it studies the children components in the labels in a recursive way.
     *
     * @param studiedNode
     * @return Text between nested tags
     */
    public String  *extactText  *(Node  studiedNode  ) {
        Node node;
        String text = "";
        boolean exit= false;

        try {
            for (SimpleNodeIterator e =
studiedNode   .getChildren().elements(); e.hasMoreNodes() && !exit;) {
                node = e.nextNode();
                if (node instanceof CompositeTag) {
                    text =  extactText  (node);
                } else {
                    if (node != null) {
                        text = node.getText();
                    }
                    exit= true;

                }
            }
        } catch (NullPointerException ex) {
            // do something
        }


        return text.trim();
    }


I hope this helps.
