The relevant content of this document are as follows:  <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> …….. </head> <body>    <div id="container">        <div id="content">            <table class="sresults">                <tr>                    <td>                        <a href="http://www.abc.com/areas" title="Hollywood, CA">hollywood</a>                    </td>                    <td>                        <a href="http://www.abc.com/areas" title="San Jose, CA">san jose</a>                    </td>                    <td>                        <a href="http://www.abc.com/areas" title="San Francisco, CA">san francisco</a>                    </td>                    <td>                        <a href="http://www.abc.com/areas" title="San Diego, CA">San diego</a>                    </td>              </tr> ………. </body> </html>  Below is the relevant code snippets illustrates how I have attempted to retrieve the contents (value of <a>):              import java.util.*;             import org.jdom.*;             import org.jdom.xpath.*;             import org.saxpath.*;             import org.ccil.cowan.tagsoup.Parser;  ( 1 )      frInHtml = new FileReader("C:\\Tmp\\ABC.html"); ( 2 )      brInHtml = new BufferedReader(frInHtml); ( 3 ) //   SAXBuilder saxBuilder = new SAXBuilder("org.apache.xerces.parsers.SAXParser"); ( 4 )      SAXBuilder saxBuilder = new SAXBuilder("org.ccil.cowan.tagsoup.Parser"); ( 5 )      org.jdom.Document jdomDocument = saxbuilder.build(brInHtml); ( 6 )      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"); ( 7 )      xpath.addNamespace("ns", "http://www.w3.org/1999/xhtml"); ( 8 )      java.util.List list = (java.util.List) (xpath.selectNodes(jdomDocument)); ( 9 )      Iterator iterator = list.iterator(); ( 10 )    while (iterator.hasNext()) ( 11 )    { ( 12 )           Object object = iterator.next(); ( 13 ) //        if (object instanceof Element) ( 14 ) //              System.out.println(((Element)object).getTextNormalize()); ( 15 )            if (object instanceof Content) ( 16 )                  System.out.println(((Content)object).getValue());              } ….  This program would work on the same document without the default namespace, hence, it would not be necessary to include “ns†prefix along in the XPath statements (line 6-7) either. Moreover, I was using “org.apache.xerces.parsers.SAXParser†to have successfully retrieve content of <a> from the same document without default namespace in the past.  I would like to achieve the following objectives if possible:  ( i ) Exclude DTD and namespace in order to simplifying the parsing process. How this could be done? ( ii ) If this is not possible, how to include it in XPath statements (line 6-7) so that the value of <a> is picked up correctly? ( iii ) Would changing from “org.apache.xerces.parsers.SAXParser†to “org.ccil.cowan.tagsoup.Parser†make any difference as far as using XPath is concerned? ( iv ) Failing to exlude DTD, how to change the lookup of a PUBLIC DTD to a local SYSTEM one and include a local DTD for reference?  I am running JDK 1.6.0_06, Netbeans 6.1, JDOM 1.1, Saxon6-5-5, Tagsoup 1.2 on Windows XP platform.  Any assistance would be appreciated.  Thanks in advance,  Jack Search 1000's of available singles in your area at the new Yahoo!7 Dating.
