Validate and continue after errors?
Hi,
I'm using the DOMParser with validation and I would like to be able to
validate the XML that I'm sucking in and parse what I can up to wherever an
error might occur. Currently, the document reference is coming back null. Is
this possible?
I'm porting & enhancing some code so I'm not totally clear on what all the
settings below are doing and the various documentation I've scrounged
(sun.com, apache.org, etc.) haven't answered my question. All comments
welcome.
Regards,
Ed
Some technical stuff...
String xmlDocument = "some_xml_file.xml";
DOMParser parser = new DOMParser(mySymbolTable, myGrammarPool)
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);
Document document = parser.getDocument();

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?
