How to Read All Attributes of an Element in VTD-XML?

There are two ways to read all the attribute values of an element node.

The first one is to use XPath expression  @* as in the example below

  ap = new AutoPilot (vn);
  ap.selectXPath(“@*”);
  int i=-1;
while((i=ap.evalXPath())!=-1){
      // i will be attr name, i+1 will be attribute value
   }

The second is lighter weight, which is by directly using autoPilot’s selectAttr() and iterAttr()

ap = new AutoPilot(vn);
ap.selectAttr(“*”);
int i=-1;
while((i=ap.iterateAttr())!=-1){
 // i will be attr name, i+1 will be attribute value
}
