Re: [Htmlparser-user] iterate through node list

[Mattia T. <mat...@gm...>]

Hi try this:

in a new class, after importing:
import org.htmlparser.tags.*;
import org.htmlparser.util.*;

insert next method:

    protected URL[] extractLinks(String url) throws ParserException {
        Parser parser;
        Vector vector;
        LinkTag link;
        URL[] ret;
        parser = new Parser(url);
        ObjectFindingVisitor visitor = new ObjectFindingVisitor(
LinkTag.class);
        parser.visitAllNodesWith(visitor);
        Node[] nodes = visitor.getTags();
        vector = new Vector();
        for (int i = 0; i < nodes.length; i++)
            try {
                link = (LinkTag) nodes[i];
                System.out.println(link.getLink() + " " + link.getLinkText
());
                vector.add(new URL(link.getLink()));
            } catch (MalformedURLException murle) {
                murle.printStackTrace();
            }
        ret = new URL[vector.size()];
        vector.copyInto(ret);

        return (ret);
    }

Hope this help.

Cheers

Mattia
