Hi!
I try to remove all <DIV>s from a Document but this seems to be somewhat
tricky :-) I'd prefer to use a Visitor; the code below throws an
NullPointerException. The second approach simply doesn't work:
import java.io.FileReader;
import java.util.List;
import java.util.Iterator;
import org.cyberneko.html.parsers.SAXParser;
import org.dom4j.Document;
import org.dom4j.Element;
import org.dom4j.Node;
import org.dom4j.VisitorSupport;
import org.dom4j.io.SAXReader;
public class Test
{
static class KillDivs extends VisitorSupport
{
public void visit( Element e )
{
if (e.getName().equalsIgnoreCase("div"))
{
e.getParent().remove(e);
return;
}
}
}
public static void main(String[] args)
{
try
{
SAXReader reader = new SAXReader(new SAXParser());
Document doc = reader.read(new FileReader("test.html"));
// doc.accept(new KillDivs());
List divs = doc.selectNodes("//DIV");
for (Iterator<Node> iter = divs.iterator(); iter.hasNext(); )
{
Node n = iter.next();
if(n.getName().equalsIgnoreCase("div"))
{
doc.remove(n);
}
}
String s = doc.asXML();
System.out.println(s.indexOf("<DIV>"));
}
catch (Exception e)
{
System.err.println("->"+e);
}
}
}
