I have the following (test)
XML file below and Java code that uses StaX. I want to apply this code to a file that is about 30 GB large but with fairly small elements, so I thought StaX is a good choice. I am getting the following error:
Exception in thread "main" javax.

Here the code:
package
xml.staxtest;
import java.io.*;
import javax.
xml.stream.*;
public class StaXTest {
public static void main(String[] args) throws Exception {
XMLInputFactory xif = XMLInputFactory.newInstance();
XMLStreamReader streamReader = xif.createXMLStreamReader(new FileReader("D:/Data/testFile.
xml"));
while(streamReader.hasNext()){
int eventType = streamReader.next();
if(eventType == XMLStreamReader.START_ELEMENT){
System.out.println(streamReader.getLocalName());
}
//... more to come here later ...
}
}
}
