    Question Question related to htmlParser

    Hello, i have to use an htmlParser and i have to visit the nodes/children in the DOM tree which attribute is href.
    It's just that i need to parse the html and gather all the links included in " " marks

    For example : <a href=" url ">

    So i have the following code :

    Java Code:
    import org.htmlparser.Parser;
     import org.htmlparser.Tag;
     import org.htmlparser.Text;
     import org.htmlparser.util.ParserException;
     import org.htmlparser.visitors.NodeVisitor;
    public class MyVisitor extends NodeVisitor
         public MyVisitor ()
         /**/    @Override
         public void visitTag (Tag tag)
             System.out.println ("\n" + tag.getTagName () + tag.getStartPosition ());
         public static void main (String[] args) throws ParserException
             Parser parser = new Parser (" whatever, link");
             NodeVisitor visitor = (NodeVisitor) new MyVisitor ();
             visitor.visitTag(/* Here i cannot place a string but only a Tag */);   // I would like to visit every Tag in the page and i'm stuck,
                                                                                                           // I don't know how to do that! 
     }'s just that i have to visit every children/node and find the nodes/elements with attribute href

    May you please help me?
    Thanks in advance! :rolleyes:

    I've been doing something like this recently. I don't use a html parser, but maybe you could adapt my code somewhat:

    I used a buffered reader and read the lines in one at a time feeding it to this code:

    Java Code:
                          String slice = "< a href=";
                          int beg = inputLine.indexOf(slice) + slice.length();
                          int end = inputLine.indexOf(">");
                          String sliced = inputLine.substring(beg, end)
    It basically extracts text between two values and creates a substring, storing it into a string
