cannot convince xerces to call ignorableWhitespace()

["Schweigl, Johann" <Jo...@softwareag.com>]

Hello there,

i'm trying to split a huge XML document via SAX and want to get rid of
whitespace between elements. The underlying schema has no mixed="true"
attribute, so I suppose every whitespace character in between elements
qualifies as ignorable. I'm overloading the ignorableWhitespace method of
DefaultHandler in BigFileHandler like this:

	public void ignorableWhitespace(char buf[], int offset, int length)
throws SAXException {
		System.err.println(".");
	}


and start the whole process in this code fragment:

try {
	factory.setNamespaceAware(true);
	factory.setValidating(true);
	
	parser = factory.newSAXParser();
	
parser.setProperty("http://java.sun.com/xml/jaxp/properties/schemaLanguage",
"http://www.w3.org/2001/XMLSchema");
	
parser.setProperty("http://java.sun.com/xml/jaxp/properties/schemaSource",
"...");
	parser.parse(new File(bigFile), new BigFileHandler());
}

However, ignorableWhitespace() never gets called. Everything is passed to
characters(). Did I miss anything? I'm using JDK 1.4.1_01, Xerces 2.4.0.

Cheers,
Johann

It's not a bug, it's a feature ;-)

Ignorablewhitespace is not defined by XMLSchema, and hence this feature
won't work when the grammar is XMLSchema. This feature works *only* when the
grammar is DTD. As Rowell mentioned, you can see:
http://xml.apache.org/xerces2-j/features.html#dom.include-ignorable-whitespa
