Hi Liam,
 
That is the bizarre thing is that this enitity resolver issue would not come up if I was to convert the original City.xhtml file to City.xml with TagSoup parser using the following codes:
 
a.  BufferedReader cityIncomingbrHtml = new BufferedReader(new FileReader("C:\City.xhtml"));b.  SAXBuilder saxBuilder = new SAXBuilder("org.ccil.cowan.tagsoup.Parser", false);
c.  cityJDOMDocument = saxBuilder.build(cityI
d.  cityOutXml = new BufferedWriter(new FileWriter(C:\City.xml));ncomingbrHtml);  XPath cityXPath = XPath.newInstance("/ns:html/ns:body/ns:div[@id='content']/ns:table[@class='sresults']/ns:tr/ns:td/ns:a/@title");
h.  java.util.List cityList = cityXPath.selectNodes(cityJDOMDocument);
i.  Iterator city_iterator = cityList.iterator();
j.  while (city_iterator.hasNext()) { 
k.     city_content = ((org.jdom.Attribute)city_iterator.next()).getValue();
l.      if (city_content.length() != 0) {
m.        System.out.println("City Url:" + city_content.toString()); }
n.   }
cityJDOMDocument);
7. Iterator city_iterator = cityList.iterator();
8. while (city_iterator.hasNext()) { 
9. city_content = ((org.jdom.Attribute)city_iterator.next()).getValue();
10. if (city_content.length() != 0) {
11. System.out.println("City Url:" + city_content.toString()); }
12. }

e.
f.  outputter.output(cityJDOMDocument, cityOutXml); 
　
g.
 
Yet it would errored out when reading the converted C:\City.xml directly as covered earlier and again as follows: 
 
1. BufferedReader incomingbrXml = new BufferedReader(new FileReader("C:\City.xml"));
2. SAXBuilder saxBuilder = new SAXBuilder(false);
3. Document jdomXmlDocument = saxBuilder.build(incomingbrXml);
4. String city_content = null;
5. XPath cityXPath = XPath.newInstance("/ns:html/ns:body/ns:div[@id='content']/ns:table[@class='sresults']/ns:tr/ns:td/ns:a/@title");
6. java.util.List cityList = cityXPath.selectNodes(
 
Looks like it is the default Sax parser possibly via JAXP that does not come with the XHTML DTDs and with an XML catalog set up to use them instead of going to www.w3.org each time.
I am still waying through the references to use XML Catalog but it doesn't appears to provide every facets to a Java solution. It would great if you could provide some example of how everything are interconnected together.
 
The 3rd option you have suggested by turning off validation with SAXBuilder.setValidating(false) does not prevent the process of resolving DTD document.
 
Thanks in advance,
Jack

First, please file a bug against whatever software you are using -
it should come with the XHTML DTDs and with an XML catalog set
up to use them instead of going to www.w3.org each time.

Second, use an XML Catalog for this. You'll need the DTD for
XML processing if you try to use entities like &eacute; that
are defined in it.

Third, you could turn off valdation, probably with something like
SAXBuilder.setValidating(false);

Or, set the Java property http://xml.org/sax/features/validation
to false.
