Nope, it's not necessary to create an LSParser.

Re: Help needed: cannot resolve symbol symbol : method getConfig ()
Posted by Mike Hao <mi...@yahoo.com>.
Hi,
I figured out the reason for the error I got. The name of the method getConfig() has been changed to getDomConfig().
Thanks,
Mike

Hi there,
I am trying to use the DOM Level 3 functionalities. I checked out the xml-xerces source from the apach CVS, and built Xerces using the jars-dom3 target, and I got two new jar files: dom3-xml-apis.jar and the dom3-xercesImpl.jar. I included these new jars in my classpath and I run a testing program, but get some compiling error:

config.setParameter("schema-type", "http://www.w3.org/2001/XMLSchema");
config.setParameter("validate", Boolean.TRUE);
config.setParameter("schema-location", "personal.xsd");
document.normalizeDocument();
} catch (FactoryConfigurationError e) {

} catch (ParserConfigurationException e) {
// parser was unable to be configured

Can anyone tell me what's going wrong?

Namespace-Aware node question
Posted by Mike Hao <mi...@yahoo.com>.
Hi there,
I have an XML document and some schemas against to this document. I used a DOM parser read in this document and then tried to use the normalizeDocument() to revalidate this DOM object. I got fatal error says:
NullLocalElementName: A null local name was encountered during namespace normalization of element
What's the cause reason of this error? What's does the namespace-aware node really mean?
Thanks,
Mike

Re: Validate DOM document in memory using DOM level 3
Posted by Mike Hao <mi...@yahoo.com>.
Hi Michael / All,
Thank you for your reply. I have successfully revalidate my in-memory DOM against a schema using the normalizeDocument() in my test progam.
>From the article:
http://www-106.ibm.com/developerworks/xml/library/x-keydom2.html
I know that if I want to use the revalidating feature of DOM level3, the node must be created using the namespace-aware method, like createElementNS(). But in my project, the code is already there, and the node is created using the Level 1 method, that is createElement(). I still want to use this new feature of DOM level 3, so is there any better way to by pass my problem? Or do you have any suggestions?
Thanks,
Mike

Hi Mike,
Yes, you want to call normalizeDocument() but first you have setup the
DOMConfiguration (see the 'schema-location', 'schema-type' and 'validate'
parameters) [1] so that the DOM will be validated when this method is
called.

Hi Neil,
Thank you for your quick response.
Which method should I use for this kind of validation? normalizeDocument()?
Thanks,
Mike
