以第一名的成績滯留而在Java解析XML

我解析以下XML：以第一名的成績滯留而在Java解析XML

<table ID="customer"> 
    <T><C_CUSTKEY>1</C_CUSTKEY><C_NAME>Customer#000000001</C_NAME><C_ADDRESS>IVhzIApeRb ot,c,E</C_ADDRESS><C_NATIONKEY>15</C_NATIONKEY><C_PHONE>25-989-741-2988</C_PHONE><C_ACCTBAL>711.56</C_ACCTBAL><C_MKTSEGMENT>BUILDING</C_MKTSEGMENT><C_COMMENT>regular, regular platelets are fluffily according to the even attainments. blithely iron</C_COMMENT></T>

與下面的Java代碼：

package xmlparserformining; 
import java.util.List; 
import java.util.Iterator; 
import org.dom4j.Document; 
import org.dom4j.DocumentException; 
import org.dom4j.Node; 
import org.dom4j.io.SAXReader; 

public class XmlParserForMining { 


    public static Document getDocument(final String xmlFileName) 
    { 
     Document document = null; 
     SAXReader reader = new SAXReader(); 
     try 
     { 
     document = reader.read(xmlFileName); 
     } 
     catch (DocumentException e) 
     { 
     e.printStackTrace(); 
     } 
     return document; 
    } 


    public static void main(String[] args) { 



     String xmlFileName = "/home/r/javaCodez/parsing in java/customer.xml"; 
     String xPath = "//table/T/C_ADDRESS"; 
     Document document = getDocument(xmlFileName); 
     List<Node> nodes = document.selectNodes(xPath); 
     System.out.println(nodes.size()); 


     for (Node node : nodes) 
     { 
     String customer_address = node.valueOf(xPath); 
     System.out.println("Customer address: " + customer_address); 
     } 
    } 

}

然而，而不是讓所有客戶的各種記錄，我得到了以下的輸出：

1500 
Customer address: IVhzIApeRb ot,c,E 
Customer address: IVhzIApeRb ot,c,E 
Customer address: IVhzIApeRb ot,c,E 
Customer address: IVhzIApeRb ot,c,E 
Customer address: IVhzIApeRb ot,c,E 
Customer address: IVhzIApeRb ot,c,E 
Customer address: IVhzIApeRb ot,c,E 
Customer address: IVhzIApeRb ot,c,E 
Customer address: IVhzIApeRb ot,c,E 
Customer address: IVhzIApeRb ot,c,E 
Customer address: IVhzIApeRb ot,c,E 
Customer address: IVhzIApeRb ot,c,E 
Customer address: IVhzIApeRb ot,c,E 
Customer address: IVhzIApeRb ot,c,E 
Customer address: IVhzIApeRb ot,c,E 
Customer address: IVhzIApeRb ot,c,E 
Customer address: IVhzIApeRb ot,c,E 
Customer address: IVhzIApeRb ot,c,E 
Customer address: IVhzIApeRb ot,c,E 
Customer address: IVhzIApeRb ot,c,E 
Customer address: IVhzIApeRb ot,c,E 
Customer address: IVhzIApeRb ot,c,E 
Customer address: IVhzIApeRb ot,c,E 
Customer address: IVhzIApeRb ot,c,E 
Customer address: IVhzIApeRb ot,c,E

等..

這裏有什麼問題？爲什麼只打印第一個記錄？

我懷疑這就是問題所在：

String customer_address = node.valueOf(xPath);

爲什麼你想再次使用XPath查詢？難道你不想要node.getText()或類似的東西嗎？
