VTD-XML doesn't return the right value, how can I modiy the query to get the right result?

问题

I'm using the following function to parse xml using VTD-XML:

final AutoPilot ap = new AutoPilot(vtdNav);
ap.selectXPath(path);
int i = -1;
/** evalXPath returns -1 if no new node is present */
while ((i =  ap.evalXPath()) != -1) {
     extractedValues.add(vtdNav.toString(i+1));
}
/** Reset the XPath */
ap.resetXPath();

But when I try to query :

<actualUnitCost>
  <chargeOrAllowance>CHARGE</chargeOrAllowance>
  <monetaryAmount currencyISOCode="USD">17.08</monetaryAmount>
</actualUnitCost>

using the path : /actualUnitCost/monetaryAmount it gives me the value as currencyISOCode instead of 17.08. How can I modify the query to get the desired result?

I've tried /actualUnitCost/monetaryAmount/text() but it doesn't yield the right answer.

回答1:

I think that is the correct behavior. If you try /actualUnitCost/monetaryAmount/text(), it will give you the text node.

Let me know if there is any question.
