Question

要求是：如果<bby:SaleTenderType>值是电子商务，它会读取SalesOrderNum并调用所需的函数（将其他节点附加到根节点）。 <bby:SaleTenderType>不是电子商务，它应该调用其他功能。

java代码如下：

//Added for giftCard
//error
Lineitems = retailChildren.item(j).getChildNodes();
for (int z1 = 0; z1 < Lineitems.getLength(); z1++) {

    if (Lineitems.item(z1).getNodeName().equalsIgnoreCase("Return")) {
        NodeList returnChild1 = Lineitems.item(z1).getChildNodes();

        for (int z2 = 0; z2 < returnChild1.getLength(); z2++) {
            if (returnChild1.item(z2).getNodeName().equalsIgnoreCase("Tender")) {

                NodeList tenderChild = Lineitems.item(z2).getChildNodes(); //Null pointer exception
                for (int z3 = 0; z3 < tenderChild.getLength(); z3++) {

                    if (tenderChild.item(z3).getNodeName().equalsIgnoreCase("bby:SaleTenderType")) {
                        System.out.println("Inside");
                        String SaleTenderType = tenderChild.item(z3).getFirstChild().getNodeValue();

                        if (SaleTenderType.equalsIgnoreCase("eCommerce")) {

                            Lineitems = retailChildren.item(j).getChildNodes();
                            for (int i2 = 0; i2 < Lineitems.getLength(); i2++) {
                                if (Lineitems.item(i2).getNodeName().equalsIgnoreCase("Return")) {
                                    NodeList returnChild = Lineitems.item(i2).getChildNodes();
                                    for (int k = 0; k < returnChild.getLength(); k++) {
                                        if (returnChild.item(k).getNodeName().equalsIgnoreCase("c360:SalesOrder")) {
                                            String POSLOGSalesOrderNo = returnChild.item(k).getFirstChild().getNodeValue();
                                            SalesOrderNo = POSLOGSalesOrderNo.substring(2, 12);
                                            String SalesOrderNum = POSLOGSalesOrderNo.substring(0, 2);
                                            if (SalesOrderNum.equalsIgnoreCase("HD") || (SalesOrderNum.equalsIgnoreCase("SV")) || (SalesOrderNum.equalsIgnoreCase("CR")) || (SalesOrderNum.equalsIgnoreCase("CW"))) {
                                                if (!prevSalesOrder.equals(SalesOrderNo)) {

        }
    }
}


//end of gift card

这里我正在阅读根节点<Return>，然后检查它是否包含<Tender> ..如果<Tender>存在（显然<bby:SaleTenderType>将存在）.. else if { {1}}不存在，则完成其他功能。

我在此行<Tender>

中获得Null指针异常

请提供您宝贵的意见提前谢谢..

空指针异常，不进入循环内部
