Elliotte,

any idea of why this thing that worked yesterday, failed to work
today?

try {

StreamingImgLister sil = new StreamingImgLister();
Builder builder = new Builder(sil);
Document doc = builder.build(mark_up,"");
:
}
catch (ParsingException ex) {
:
}
catch (IOException ex) {
System.out.println(ex);
}

I get this exception, which I wasn't getting yesterday.

java.net.UnknownHostException: www.wapforum.org

The mark_up string contains the following:

----------------------------------------------------------------------
<?xml version="1.0"?>
<!DOCTYPE html PUBLIC "-//WAPFORUM//DTD XHTML Mobile 1.0//EN"
"http://www.wapforum.org/DTD/xhtml-mobile10.dtd";>

<html xmlns="http://www.w3.org/1999/xhtml"; xml:lang="en">

<title>Cool Portal</title>

<style>
table.coolmenu {width:100%}
td.coolmenu
{text-align:center;font-size:smaller;width:50%;vertical-align:top;}
img.coolmenu {vertical-align:top;}
</style>

</head>

<body>
<table class="coolmenu">

<tr><td class="coolmenu">

:

<a href="http://url1";>More</a>
</td>

<td class="coolmenu"></td></tr></table>

</body>
</html>
-----------------------------------------------------------

here is the StreamingImgLister.java too:
-----------------------------------------------------------

import java.io.*;
import java.util.ArrayList;
import nu.xom.*;

public class StreamingImgLister extends NodeFactory {

int depth = 0;
Nodes empty = new Nodes();
ArrayList urls = new ArrayList(20);

// We don't need the comments.
public Nodes makeComment(String data) {
return empty;
}

// We don't need text nodes at all
public Nodes makeText(String data) {
return empty;
}

public Element startMakingElement(String name, String namespace) {
return new Element(name, namespace);
}

public Nodes finishMakingElement(Element element) {

//get picture url
if (element.getLocalName().equals("img")) {
if (element.getAttributeValue("src") != null) {
System.out.println(element.toXML());
urls.add(element.getAttributeValue("src"));
}
}
//get CSS url
if (element.getLocalName().equals("link")) {
if ("stylesheet".equals(element.getAttributeValue("rel")) &&
element.getAttributeValue("href") != null) {

System.out.println(element.toXML());
urls.add(element.getAttributeValue("href"));
}
}

if (element.getParent() instanceof Document) {
return new Nodes(element);
}
else return empty;
}

public Nodes makeAttribute(String name, String URI,
String value, Attribute.Type type) {
if (name.equals("src") || name.equals("href") || name.equals("rel") )
{
return new Nodes(new Attribute(name, URI, value, type));
}
return empty;
}

public Nodes makeDocType(String rootElementName,
String publicID, String systemID) {
return empty;
}

public Nodes makeProcessingInstruction(String target, String data) {
return empty;
}

/* export urls */
public ArrayList getUrls() {
return urls;
}

}
-----------------------------------------------------------

is there a way to force the Builder to ignore DTDs?
I already do this:

public Nodes makeDocType(String rootElementName,
String publicID, String systemID) {
return empty;
}

thanks

Luca
