Re: [Htmlparser-user] Can't extract any div's, redux.

[Derrick O. <der...@gm...>]

Using the FilterBuilder
tool<http://htmlparser.sourceforge.net/samples.html>is a good way to
play with filters.
Using that for a minute I got this code which fetches your storybook text:

import org.htmlparser.*;
import org.htmlparser.filters.*;
import org.htmlparser.beans.*;
import org.htmlparser.util.*;

public class StorytextFilter
{
    public static void main (String args[])
    {
        TagNameFilter filter0 = new TagNameFilter ();
        filter0.setName ("DIV");
        HasAttributeFilter filter1 = new HasAttributeFilter ();
        filter1.setAttributeName ("id");
        filter1.setAttributeValue ("storytext");
        NodeFilter[] array0 = new NodeFilter[2];
        array0[0] = filter0;
        array0[1] = filter1;
        AndFilter filter2 = new AndFilter ();
        filter2.setPredicates (array0);
        NodeFilter[] array1 = new NodeFilter[1];
        array1[0] = filter2;
        FilterBean bean = new FilterBean ();
        bean.setFilters (array1);
        if (0 != args.length)
        {
            bean.setURL (args[0]);
            System.out.println (bean.getNodes ().toHtml ());
        }
        else
            System.out.println ("Usage: java -classpath
.;htmlparser.jar;htmllexer.jar StorytextFilter <url>");
    }
}


Then you can apply the StringBuiler to the NodeList using the visitor
pattern.
