Validating without parsing
Hi,
I was wondering if the XNI component approach to building a parser would
make it easy to use the XMLSchemaValidator or XMLDTDValidator to
validate generated XML fragments, without parsing a document.
Oh, and by the way. Is anything included in Xerces 2 that can serialize
SAX events into a document?
TIA,

Great. What would then be the best way to specify a filename, Reader or
similar with the schema data in it?

Sure, that's possible but there's currently no code to
make this doable directly.

Check out the org.apache.xml.serialize package. You could
also use a SAXSource as an input to Xalan (via TrAX) and
the identity transform (i.e. no stylesheet) to do the same
thing.

Thanks,
I'm going to try it.

You will have to XMLize your HTML before using the DOMParser - tools for
these
are NekoHTML and JTidy.

Not yet, this is a new feature.
Here are couple of suggestions on how to validate against XMLSchema:
1) Create your own parser configuration that includes all the
features/properties needed by XMLSchemaValidator.
The configuration is needed, so you can easily reset()
XMLSchemaValidator. For examples, see dom.DOMRevalidationConfiguration.
2) To specify location of the schema, you could:
a) Use properties:
http://apache.org/xml/properties/schema/external-schemaLocation and
http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation
b) specify schemaLocation attributes at the root element
3) XMLSchemaValidator also implements impl.RevalidationHandler that
allows you to set baseURI relative to which the resolution of schema
location should occur. The handler also has an additional method to pass
characters as strings (instead of XMLString).
Note: this is experimental code: the implementation can be
changed/removed or modified. (So you might need to change your code in
the future..)

How can I parse HTML not XTML?
Posted by Marcial Atienzar <ma...@servicom2000.com>.
Hello,
I've this code:
DOMParser parser = new DOMParser();
HTMLDocument document = null;
try {
parser.setProperty("http://apache.org/xml/properties/dom/document-class-name
",
"org.apache.html.dom.HTMLDocumentImpl");
parser.parse(archivo);
document = (HTMLDocument)parser.getDocument();
...
And with this code I can't parse HTML, only XHTML. I've an error when I try
to do it. A lot of thanks,
Marcial Atienzar Navarro

Great. That looks like, I can do something simlar then.

Actually I'm only searching for the best way to instantiate an
XMLSchemaValidator or XMLDTDValidator, specify some named resource to
load the grammar from, and the rest *should* be a breeze...
Does anybody have any good suggestions or pointers for relevant
documentation?

Yes, this is the approach we used to implement DOM revalidation in
Xerces.
I expect more discussion on revalidation design on xerces-j-dev list.
If you are interested, please subscribe to this list.
Thank you,
