```
NodeList spanNode = (NodeList) xpath.evaluate("/widgets/widget[3]/node()", inputSource, XPathConstants.NODESET);
for(int i = 0; i < spanNode.getLength(); i++) {
Node node = spanNode.item(i);
if(node.getNodeType() == Node.TEXT_NODE) {
System.out.println(spanNode.item(i).getTextContent());
}
}
```
```
