Validation using DOM Parser

[Sebastian Will <ju...@gmx.net>]

Hi all, 
this might be a questions that's already been asked, but the mailing archive is not reachable at the moment. I'm fairly new to Xerces and while I initially worked with the XML4J from alphaworks.ibm.com, I'm now switching to Xerces which I just downloaded a sec ago (I know they should be almost the same, but...). With XML4J, there was at least in the most recent version no possibility to validate a XML file when I create a org.w3c.dom.Document using the DOMParser. I registered an ErrorHandler, who works if I use wrong XML syntax as an input, but it does not seem to report any violations against a internal DTD. 

Please correct me, if I'm wrong, but this XML file is not valid:

<?xml version="1.0" encoding="iso-8859-1" ?>
<!DOCTYPE article
[
<!ELEMENT title (#PCDATA)>
]>
<title>Test
   <elem>bla</elem>
</title>

My Java application does the following:

DOMParser parser = new DOMParser();
parser.setErrorHandler(new DefaultErrorHandler());
...
parser.parse(Util.genURI(files[i].getAbsolutePath()));
document = parser.getDocument();

Shouldn't be parse errors reported by the DefaultErrorHandler I registerd within the parser? Or do I have to use a SAXParser instead, he does validate the XML data, doesn't he? 

Please give me a kick into the right direction, thanks!

nodeset() extention in xalan - please help.

[Kiran Halwai <kh...@winphoria.com>]

Hello:

I could not find xalan user mailing list so posting it here - sorry about
that.

I am struggling with nodeset() extention in xalan. Following are the
templates. I have included xalan.jar,
xerces.jar, bsf.jar in the classpath - rather in lib directory of tomcat.
I am getting following error msg -

"Call to extension function failed: http://xml.apache.org/xalan".

I would really appreciate your help to solve this problem.

Also, is it possible to pass a path of XML element to nodeset(). XML file
could like this.

  <start>
             <option value="alf">A</option>
             <option value="bar">B</option>
             <option value="cat">C</option>
             <option value="dog">D</option>
             <option value="elf">E</option>
             <option value="foo">F</option>
     </start>

Best Regards,
Kiran

You could start by reading the instructions on

http://xml.apache.org/xerces-j/index.html

You have to turn on validation, or else the parser will just parse, and 
generate a DOM, without validating your document.

You will find what you need under 'features' in the menu to the left.
