Hi Nicholas,

Thanks for responding to my question. 

I can confirm that the XPath using Saxon parser ("org.ccil.cowan.tagsoup.Parser") is working with default namespace. I made the mistake of assuming that the XML document converted by TagSoup was identical to using light_html2xml in the past. 

Consequently, what is outstanding still, even though not critical, but nice to have, is ( i ) to exclude DTD from XML file. If this is not possible, ( iv ) to setup local SYSTEM EntityResolver in this JDOM environment.

Below is an example of what I am trying to achieve in ( iv ) in a DOM environment:
 
import java.io.IOException;
import java.io.StringReader;
 
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
 
import org.w3c.dom.Document;
import org.xml.sax.EntityResolver;
import org.xml.sax.InputSource;
import org.xml.sax.SAXException;
 
 
public class ParseExamples
{
    private final static String COMMON_XML
        = "<music>"
        +     "<artist name=\"Anderson, Laurie\">"
        +         "<album>Big Science</album>"
        +         "<album>Strange Angels</album>"
        +     "</artist>"
        +     "<artist name=\"Fine Young Cannibals\">"
        +         "<album>The Raw &amp; The Cooked</album>"
        +     "</artist>"
        + "</music>";
 
 
    private final static String COMMON_DTD
        = "<!ELEMENT music (artist*)>"
        + "<!ELEMENT artist (album+)>"
        + "<!ELEMENT album (#PCDATA)>"
        + "<!ATTLIST artist name CDATA #REQUIRED>";
 
 
 
    public static void main(String[] argv)
    throws Exception
    {
        // this version uses just a SYSTEM identifier - note that it gets turned
        // into a file: URL
        String xml = "<!DOCTYPE music SYSTEM \"bar\">"
                   + COMMON_XML;
 
        // this version uses both PUBLIC and SYSTEM identifiers; the SYSTEM ID
        // gets munged, the PUBLIC ID doesn't
//        String xml = "<!DOCTYPE music PUBLIC \"foo\" \"bar\">"
//                   + COMMON_XML;
 
        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        dbf.setValidating(true);
        DocumentBuilder db = dbf.newDocumentBuilder();
        db.setEntityResolver(new EntityResolver()
        {
            public InputSource resolveEntity(String publicId, String systemId)
                throws SAXException, IOException
            {
                System.out.println("publicId = " + publicId);
                System.out.println("systemId = " + systemId);
                return new InputSource(new StringReader(COMMON_DTD));
            }
        });
 
        Document dom = db.parse(new InputSource(new StringReader(xml)));
        System.out.println("root element name = " + dom.getDocumentElement().getNodeName());
    }
}

Would anyone be able to give me some idea on how to do this?
Thanks a lot again,

Jack

Jack,
It seems to be only the Ant build for Tagsoup that requires Saxon 6.5.
You can run the binary distribution (tagsoup-1.2.jar) without Saxon and, as
Michael has pointed out, the code you posted has no dependency on Saxon.
You may have an environment or classpath issue given that the following
class (which is your code with typo 'saxbuilder' changed to 'saxBuilder'),
outputs what you are expecting:

===================
OUTPUT:
===================
hollywood
san jose
san francisco
San diego

JAVA CLASS:

import java.io.FileReader;
import java.util.Iterator;

import org.jdom.Content;
import org.jdom.input.SAXBuilder;
import org.jdom.xpath.XPath;

public class Test {
      @SuppressWarnings("unchecked")
      public static void main(String[] args) {
            try {
                  FileReader frInHtml = new
FileReader("C:\\Temp\\ABC.html");
                  BufferedReader brInHtml = new BufferedReader(frInHtml);
                  SAXBuilder saxBuilder = new SAXBuilder(
                              "org.ccil.cowan.tagsoup.Parser");
                  org.jdom.Document jdomDocument =
saxBuilder.build(brInHtml);
                  XPath xpath = XPath

.newInstance("/ns:html/ns:body/ns:div[@id='container']/ns:div[@id='content']
/ns:table[@class='sresults']/ns:tr/ns:td/ns:a");
                  xpath.addNamespace("ns", "http://www.w3.org/1999/xhtml");
                  List list = (List) (xpath.selectNodes(jdomDocument));
                  Iterator iterator = list.iterator();
                  while (iterator.hasNext()) {
                        Object object = iterator.next();
                        if (object instanceof Content)
                              System.out.println(((Content)
object).getValue());
                  }
            } catch (Exception e) {
                  e.printStackTrace();
            }
      }
}
