Re: [xml-dev] How to parse XML document with default namespace with

Hi Michael,

Thanks for responding to this question.

I have not had any luck with jdom-interest@j... forum at all since subscribing to them a few months back.

In the meantime, can you confirm that it is not possible to use Sax 6.5.x with JDOM according to http://www.cafeconleche.org/books/xmljava/chapters/ch16s05.html? Or is it because you are not familiar with JDOM?

Could anyone point me to a more useful JDOM forum to assistance with this question?

Many thanks,

Jack

I see no Saxon code here.. You are using the XPath engine that comes with JDOM. You might be better off asking on the JDOM list. I have to confess I'm surprised to see you declaring namespaces AFTER compiling the XPath expression, but I can't say I'm familiar with this API.

Subject: [xml-dev] How to parse XML document with default namespace with JDOM XPath


Hi All,
 
I am having difficulty parsing using Saxon and TagSoup parser on a namespace html document. 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
