I have an interesting design problem and wondered if
the gurus would have insight into it.
I need to have an html file that contains or embeds
data in xml and can be parsed by SAX.
My xml file is like this:
<?xml version="1.0" encoding="ISO-8859-1"?>
<JWO
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="C:\Projects\ACD\jwo_schema01.xsd">
</JWO>
I want to put it inside or embed it in an html file.
The HTML file will be parsed by a SAX
parser, the html ignored, and the XML data extracted.
When I posted this question long ago, some
(Megginson, Dane...) suggested I put the xml in
the <head> tags and use xhtml.
So I implemented this:
---------
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0
Transitional//EN" "
http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
<xml version="1.0" encoding="ISO-8859-1">
<JWO
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="C:\Projects\ACD\jwo_schema01.xsd">
</JWO>
</xml>
<title></title>
<meta http-equiv="KEYWORDS" content=""/>
<meta http-equiv="DESCRIPTION" content=""/>
</head>
Rest of the html.............
----------
In my content handler,
public void characters(char[] text, int start, int
length) throws SAXException {
if(skipContent) {
skipContent = false;
return;
}
else..............
public void startElement(String namespaceURI, String
localName, String qualifiedName,
Attributes atts) throws SAXException {
if(!namespaceURI.equalsIgnoreCase("http://www.w3.org/2001/XMLSchema-instance
")) {
skipContent = true;
return;
} else............
public void endElement(String namespaceURI, String
localName, String qualifiedName)
throws SAXException {
if(!namespaceURI.equalsIgnoreCase("http://www.w3.org/2001/XMLSchema-instance
")) {
skipContent = false;
return;
} else............
-----------
However I get parse errors
eg.
java.net.UnknownHostException: www.w3.org
at java.net.PlainSocketImpl.connect(Unknown Source)
When I simply remove the <xml> tag and keep it as:
<?xml version="1.0" encoding="ISO-8859-1"?>
ie. inserting the xml file in between the <head>
elements,
then "namespaceURI"= "http://www.w3.org/1999/xhtml"
even while parsing the xml, so it fails
Anyone knows how to do this?
Or is the answer that it cannot be done?

Any help appreciated plus you will have the
gratification of having contributed to a useful XML
tool that IMHO will benefit society.
sincerely,
Anil
