RE: Validate and continue after errors?

[Murphy, Ed]

Hi Michael,

Thanks for the reply...your comments got me thinking so I went back to take
a look and you're right. The try/catch logic was preventing it from getting
to the "getDocument" statement (the returned error was a SAXException from
the parse step.)

Here's a more accurate code snippet of how it looks now (should've posted
this before!)

                DOMParser parser = new DOMParser(mySymbolTable,
myGrammarPool);
                
                try {
        
parser.setFeature("http://xml.org/sax/features/namespaces";, true);
        
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/validation/schema-full-che
cking", true);
        
parser.setProperty("http://java.sun.com/xml/jaxp/properties/schemaLanguage";,
"http://www.w3.org/2001/XMLSchema";);                    
                        parser.parse(xmlDocument);
                } catch (SAXNotRecognizedException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                } catch (SAXNotSupportedException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                } catch (SAXException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                }
                
                this.document = parser.getDocument();

Earlier ths getDocument statement was *in* the try block, so it wasn't
getting executed.

I't working like I expect it now. Thanks for the help!

Regards,
Ed

Hi Ed,

That could happen if the parser threw an exception from parse before the 
Document node is created, for instance from an IOException thrown from an 
unsuccessful attempt to open the URL you specified. I don't see a 
try/catch block in your code snippet. Is the parser returning normally?
