Question

我无法读取分支编号。

XML：

<NODE>   
 <EMPLOYEENUMBER EMPLOYEENUMBER="1334350"/>
 <BranchNumber BRANCHCUSTOMERNUMBER ="400823482"/>
 <BR AfterImage="51" BeforeImage=""/>
 <DEALNO="6698398" BeforeImage=""/>
 <SEQ AfterImage="0" BeforeImage=""/>
 <TRAD AfterImage="PHSS" BeforeImage=""/>
 <VDATE AfterImage="2017-04-07 00:00:00.0" BeforeImage=""/>
 <CUST AfterImage="10075222" BeforeImage=""/>
 <BROK AfterImage="" BeforeImage=""/>
 <BROKCCY AfterImage="UGX" BeforeImage=""/>
 <BROKAMT AfterImage="0.0000" BeforeImage=""/>
 <PHONCI AfterImage="0" BeforeImage=""/>
 <PORT AfterImage="CSPO" BeforeImage=""/>
 <COST AfterImage="30000003" BeforeImage=""/>
 <ODATE AfterImage="2017-03-02 00:00:00.0" BeforeImage=""/>
 <DEALDATE AfterImage="2017-03-02 00:00:00.0" BeforeImage=""/>
 <DEALTIME AfterImage="06:12" BeforeImage=""/>
 <IOPER AfterImage="RAMU" BeforeImage=""/>
 <VOPER AfterImage="RAMU" BeforeImage=""/>
 <BROKCDATE AfterImage="" BeforeImage=""/>
 <CUSTCDATE AfterImage="" BeforeImage=""/>
 <PHONECDATE AfterImage="" BeforeImage=""/>
 <DEALTEXT AfterImage="" BeforeImage=""/>
 <PHONETEXT AfterImage="" BeforeImage=""/>
 <PS AfterImage="S" BeforeImage=""/>
 <PRODCODE AfterImage="XYZ" BeforeImage=""/>    
</NODE>

爪哇：

for (int temp = 0; temp < nList.getLength(); temp++) {

    Node nNode = nList.item(temp);

    System.out.println("\nCurrent Element :" + nNode.getNodeName());

    if (nNode.getNodeType() == Node.ELEMENT_NODE) {
        Element eElement = (Element) nNode;
        System.out.println(" EMPLOYEENUMBER: " + eElement.getAttribute("EMPLOYEENUMBER"));
        System.out.println("BRANCHCUSTOMERNUMBER : " +  eElement.getAttribute("BRANCHCUSTOMERNUMBER"));
    }
}

如果我读'BRANCHCUSTOMERNUMBER'，它就是空的。

您可以尝试以下代码。

public static double distance(Location start, Location end) {
    try {
        double distance = start.distanceTo(end);
        DecimalFormat decimalFormat = new DecimalFormat("#.#");
        DecimalFormatSymbols custom = new DecimalFormatSymbols();
        custom.setDecimalSeparator('.');
        decimalFormat.setDecimalFormatSymbols(custom);
        double distanceFormated = 
        Double.parseDouble(decimalFormat.format(distance));
        return distanceFormated;
    } catch (Exception e) {
        e.printStackTrace();
    }
    return 0;
}

使用java从XML文件中读取值
