I've html/xml files that contain the following:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

The Java program that I create parses this file however it won't compile b/c it's trying to visit the w3 site for the DTD info.  Any idea if this function can be turned of in Java/Eclipse?

Howdy, newbieal.

If I am not mistaken you have been working with javax.xml.parsers, so you want to take a look at DocumentBuilderFactory: http://java.sun.com/j2se/1.4.2/docs/api/javax/xml/parsers/DocumentBuilderFactory.html.

I believe you want to use .setValidating(false).

Hi mwvisa1,
I added this line:
dbf.setValidating(false);
(dbf being the documentbuildfactory)

However, it's still trying to validate.

Not sure as your code and file work on my system just fine without any change in options.  However, you can try this setting:

dbf.setExpandEntityReferences(false);

You can look through the other settings in DocumentBuilderFactory API I linked to above, as maybe I have just not used something that is spelled out in there.

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();

dbf.setValidating(false);

dbf.setNamespaceAware(false);

dbf.setExpandEntityReferences(false);

			

DocumentBuilder db = dbf.newDocumentBuilder ( );

	    	

Document doc = db.parse ( new File ( "testing.html" ) );

	   

String newinfo = "add this line";

	   

Element root = doc.getDocumentElement ( );

System.out.println ( root.getNodeName ( ) );

NodeList list = root.getChildNodes ( );

for ( int i = 0; i < list.getLength ( ); i++ ) 

{

   if ( list.item ( i ).getNodeName ( ).equals ( "head" ) ) 

{

       list.item ( i ).setTextContent ( newinfo );

}

}

XMLSerializer serializer = new XMLSerializer ( );

serializer.setOutputCharStream ( new java.io.FileWriter ( "testing.html" ) );

serializer.serialize ( doc );

Open in new window

Yep, that is what I have with this as imports:
import java.io.File;

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;

import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.NodeList;

import com.sun.org.apache.xml.internal.serialize.XMLSerializer;

I don't understand why you do not get the connection timed out error.  Maybe it just means that your system is able to go out and verify the dtd.

I'm still getting: java.net.ConnectException: Connection timed out: connect

any other ideas? (I really just want to remove the doctype lines in the xml/html files but unfortunately I can't do that - it's a requirement that they stay in)

Yes, it is strange as you have an Internet connection since you are posting here. :)
Should not have anything to do with it, but guess you can check your firewall settings to see.

I just don't want it to connect at all.  I want it to ignore the validation of dtd.

And that should definitely be the .setValidating(false) which is why I am not sure why this isn't working for you.

Check your java version, project settings, etc. and make sure nothing weird is going on there.  I am on system with Eclipse/NetBeans and JDK 1.6 and works with setValidating(false).
