It has been too long. Hopefully you have a working solution by now. But here
is the solution any way -
As David said, you gotta get to the text node of the element to get a value
XalanNode *node = theEvaluator1->selectSingleNode(
theDOMSupport,
theContextNode,
XalanDOMString(xpath).c_str(),
(*thePrefixResolver1));
cout<<"outputA is "<<node->getNodeValue()<<endl; //No value
cout<<"outputB is "<<node->getNodeName()<<endl;
XalanNode *child = node->getFirstChild();
// For a non-leaf node, this gives the child node or
whitespace(if any)
// For a leaf node, this gives the text node
if (child!=NULL) {
result =
string(convertXalanDOMString(child->getNodeValue()));
if (trim(result).length()>0) {
cout<<"got it "<<trim(result)<<endl;
} // No need to go further. You had a leaf node
else {
while (child!=0) {
if (child->getFirstChild()!=NULL) {
//This is NULL for whitespace as
the current node
cout<<"Value is
"<<child->getFirstChild()->getNodeValue()<<endl;
cout<<"output2 is
"<<child->getNodeName()<<endl;
}
child = child->getNextSibling();
}
}
}
Note: convertXalanDOMString is my custom function - you may ignore it.
This code snippet would give you values for "/bookstore/book[1]" and also
for "/bookstore/book[1]/author"
For your second question about year, you have to get a nodelist and then
iterate through it to get individual years. I do not know of any way for
xapth to give it directly.
Try the theEvaluator1->selectNodeList(....) Hopefully this helps.
