Ignoring whitespace with schema validation
I'm having problems getting Xerces-j 1.3.0 to really ignore
whitespace. I'm getting the same problem with complicated docs and
schemas, but I'm able to reproduce it with a very simple doc and
schema.
Here's my test XML doc:
<?xml version="1.0"?>
<test xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="data/test.xsd">
</test>
Here's my schema:
<schema xmlns="http://www.w3.org/2000/08/XMLSchema">
<element name="test" type="TestType"/>
<complexType name="TestType">
</complexType>
</schema>
And here's the code where I initialize the parser:
private DOMParser getNewParser() {
DOMParser parser = new DOMParser();
try {
parser.setIncludeIgnorableWhitespace(false);
parser.setFeature("http://xml.org/sax/features/validation", true);
parser.setFeature(
"http://apache.org/xml/features/validation/schema",
true);
parser.setFeature(
"http://apache.org/xml/features/dom/include-ignorable-whitespace",
false);
} catch (Exception e) {
// ???
e.printStackTrace();
}
return parser;
}
(I've tried it with and without the "validation/schema" feature, and
it fails in the same way.)
Yet, even with all that, I still get a whitespace #text node under
the <text> node in my document, and isIgnorableWhitespace() returns
false on that node. But, I know that the parser is finding the
schema (because if I put a syntax error in the schema, it barfs).
Although, interestingly enough, the parse succeeds even when it barfs
on the schema, and I get the same result.
I'm sure this is some obvious newbie error, but I'm stumped. Any help?

Unfortunately, turning on namespaces doesn't help the problem either.
Thanks, though; I'm assuming it's exactly that kind of newbie error.

I believe you also need the namespaces feature turned on to make schema
validation work.
