Whitespace problem - Xerces & Java - Anyone?

[John (archive)]

I have been trying with no result, to force Xerces parsers to ignore whitespace in my XML file. I have tried several of the NG suggested setFeature methods in DOMParser to no avail.

I have now started to use the newest version of Xerces and as a result I stopped using DOMParser. The following fragment of my code shows how I create the parser and parse my XML file, which still has <null> #text fields for whitespace. How can I force Xerces to ignore them?

Thanks,
John

Java Code:

public class XMLConvert {

private DocumentBuilderFactory builderFactory;
private DocumentBuilder docFactory;
private Document inDoc;

public static void main(String args)
{
XMLConvert xml = null;

try {
xml = new XMLConvert(new FileInputStream(new File(args[0]))); } catch(Exception e) { e.printStackTrace; }

}

public XMLConvert(InputStream is)
{
try {
builderFactory = DocumentBuilderFactory.newInstance;

docFactory = builderFactory.newDocumentBuilder;

inDoc = docFactory.parse(is);
} catch(Exception e) {
e.printStackTrace;
}
}

My simple XML file:
<?xml version="1.0" encoding="UTF-8"?>
<Envelope>
<Body>
Test
</Body>
</Envelope>

Output from Java (children of root element):

Node Name: #text
Local Name: null
URI: null

Node Name: Body
Local Name: null
URI: null

Node Name: #text
Local Name: null
URI: null

Hi,

this method allow white spaces to be ignored :
builderFactory.setIgnoringElementContentWhitespace(true); but you must specify a grammar (a DTD) for your document (the parser can't guess which spaces can be ignored)

see JAXP documentation :
http://java.sun.com/j2se/1.4.2/docs/api/javax/xml/parsers/DocumentBuilderFactory.html
