示例1: apply
import play.libs.XPath; //导入依赖的package包/类
@Override
public List<String> apply(WSResponse response) {
List<String> timestamps = new ArrayList<>();
try {
org.w3c.dom.Document xml = response.asXml();

for (int i=0; i < nodes.getLength(); i++) {
Node node = nodes.item(i);
if (waybackTimestamp == null || node.getTextContent().compareTo(waybackTimestamp) > 0)
timestamps.add(node.getTextContent());
}

* Retrieve location by URL
* @param sURL
* @return
*/
private static Promise<Location> getLocationByURL(String sURL){
