How To Process Huge XML Documents Using Extended VTD-XML?
// description of your code here
This example shows you how to use extended VTD-XML and XPath to process XML documents bigger than 2GB. To use it, your application needs to include com.ximpleware.extended and be run within a 64-bit JVM.
/**
* This is a demonstration of how to use the extended VTD parser
* to process large XML file. You need 64-bit JVM to take full
* advantage of extended VTD.
*/
import com.ximpleware.extended.*;
public class mem_mapped_read {
public static void main(String[] s) throws Exception{
VTDGenHuge vg = new VTDGenHuge();
if (vg.parseFile("test.xml",true,VTDGenHuge.MEM_MAPPED)){
VTDNavHuge vnh = vg.getNav();
AutoPilotHuge aph = new AutoPilotHuge(vnh);
aph.selectXPath("//*");
int i = 0;
while ((i=aph.evalXPath())!=-1){
System.out.println(" element name is "+vnh.toString(i));
}
}
}
