Hi everyone,
I am trying to use the Xerces parsers for xml schema validation within
Java code. I use the parse function from the XMLParser class, that
DOMParser inherits from. This function throws two kinds of exceptions:
IOException and SAXException. But what if the xml file I am supplying is
well formed and NOT valid? DOes it throw any kind of exception? My
program just outputs an error message saying that the file was not valid.
I want my function to be able to return a 0 if the parsing was
unsuccessful, but I can't do that if there are just error messages being
outputted. This is my code.....can someone help me please!
import org.apache.xerces.parsers.DOMParser;
import org.apache.xerces.parsers.*;
import org.w3c.dom.Document;
import org.xml.sax.SAXException;
import org.xml.sax.SAXNotRecognizedException;
import org.xml.sax.SAXNotSupportedException;
import java.io.IOException;
public class DOMParserDemo
{
private static void setFeature(DOMParser parser, String feature,
boolean setting)
{
try
{
parser.setFeature(feature, setting);
}
catch (SAXNotRecognizedException e)
{
System.out.print("Unrecognized feature: ");
System.out.println(feature);
}
catch (SAXNotSupportedException e)
{
System.out.print("Unrecognized feature: ");
System.out.println(feature);
}
}
public static void main (String args[])
{
DOMParser parser = null;
parser = new DOMParser();
Document doc = null;
setFeature(parser, "http://xml.org/sax/features/validation";,
true);
setFeature(parser,
"http://apache.org/xml/features/validation/schema",true);
setFeature(parser,
"http://apache.org/xml/features/validation/schema-full-checking";, true);
try
{
parser.parse("C:/Program Files/Xinox Software/JCreator
LE/MyProjects/soaptest/XsuTest/SQRT.xml");
}
catch (IOException ie)
{
System.out.println("Could not read file.");
}
catch (SAXException e)
{
System.out.print("Could not create Document: ");
System.out.println(e.getMessage());
}
catch (Exception e)
{
System.out.print("Error occurred\n");
}
System.out.println("done\n");
}
}
Thanks,
Kavita
