这是XML文件:
<TestCase name="SearchPromotions" type="DDTC" recovery="false" datatable="HsbcDemoSearchPromotionstestCaseSpecificVirtualDatatable" position="0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="file://C:/New folder/VTAF/base-qa-3.0.5.2/generator/xsd/TestCase.xsd">
<SelectedDataTableNames name="SearchData"> </SelectedDataTableNames>
<Open page="hsbc" ms="5000" />
<Click object="hsbc.Personal_Link" />
<Click object="hsbc.CreditCard_tab" />
<Call businessComponent="Global.Verify_Search">
<Param name="HotelName_Param" value="@SearchData_link" />
</Call>
<CheckElementPresent object="hsbc.Img_Hotel_logo" Identifire="Hotel_Name_PARAM:@SearchData_ResultHotelName" fail="true" customErrorMessage="Searched hotel name is not present in the page." />
</TestCase>
以下是从指定元素获取属性的java代码。如果我尝试运行它是给NullpointException。我不知道缺少什么或者是什么错。请任何人帮助我。我已经评论了发生异常的行:
File fXmlFile = new File("SearchPromotions.xml");
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(fXmlFile);
doc.getDocumentElement().normalize();
Element docEle = doc.getDocumentElement();
NodeList nl = docEle.getChildNodes();
if (nl != null && nl.getLength() > 0) {
for (int i = 0; i < nl.getLength(); i++) {
if (nl.item(i).getNodeType() == Node.ELEMENT_NODE) {
Element ele = (Element) nl.item(i);
switch(ele.getNodeName()){
case "Click":
System.out.println(ele);
//----------------
System.out.println(ele.getAttributes().getNamedItem("page").getNodeValue());
//----------------
break;
default:
break;
}
}
}
}
答案 0 :(得分:1)
你的元素
<Click object="hsbc.Personal_Link" />
<Click object="hsbc.CreditCard_tab" />
没有名为&#34; page&#34;的属性,只有一个名为&#34; object&#34;的属性,所以通过
访问ele.getAttributes().getNamedItem("page").getNodeValue();
必须产生NullPointerException
。唯一具有&#34;页面的元素&#34;属性是
<Open page="hsbc" ms="5000" />

您尝试获取page
元素的Click
属性,但它只包含object
属性。
因此,执行ele.getAttributes().getNamedItem("page").getNodeValue()
getNamedItem("page")
时会返回null
。
