解析到Cdc下的BankMessage的value值

以下是java代码

import java.io.File;
import java.util.List;
import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;

public class Main {
public static void main(String[] args) {
SAXReader saxReader = null;
Document doc = null;
try {
saxReader = new SAXReader();
doc = saxReader.read(new File("./ss.xml"));
List<Element> list = doc.selectNodes("//root//Cdc//CdcEntry//Items//CdcEntryItem");
for (Element CdcEntryItem : list) {
String key = CdcEntryItem.elementTextTrim("Key");
if("BankMessage".equals(key)) {
System.out.println(CdcEntryItem.elementTextTrim("Value"));
return;
}
}
} catch (DocumentException e) {
}
}
}
