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

Posted January 10, 2011
Filed under: Uncategorized |

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
}

what if I want to have one element’s all attribute values read into a linkedlist and have that element’s sibling’s all attribute values read into another linkedlist? How can i implement this requirement? looking forward to your reply!

  how to construct a list is not something vtd-xml offers, you have to do it yourself. To access all attributes, just instantiate autoPilot and select attr() and iterateAttr()
