我有这个 XML 文件。我只是解析这个 XML 文件。这个例子展示了如何通过“名称”获取节点,并显示值。如何显示数据库中的所有记录?
<data399173_eff_sor>
<record>
<ID>1</ID>
<item_no>1.0</item_no>
<description>Hack off tiles and make good walls</description>
<price>100</price>
<base_qty>50</base_qty>
<var_qty>20</var_qty>
<base_price_>5000</base_price_>
</record>
<record>
<ID>1</ID>
<item_no>1.03</item_no>
<description>Test</description>
<price>45</price>
<base_qty>100</base_qty>
<var_qty>4500</var_qty>
<base_price_>0</base_price_>
</record>
</data399173_eff_sor>
等等
Java 代码
File fXmlFile = new File("D:/formdata.xml");
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(fXmlFile);
doc.getDocumentElement().normalize();
System.out.println("Root element :" + doc.getDocumentElement().getNodeName());
NodeList nList = doc.getElementsByTagName("record");
System.out.println("----------------------------");
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("Item No : " + eElement.getElementsByTagName("item_no").item(0).getTextContent());
System.out.println("Description : " + eElement.getElementsByTagName("description").item(0).getTextContent());
System.out.println("price : " + eElement.getElementsByTagName("price").item(0).getTextContent());
System.out.println("base qty : " + eElement.getElementsByTagName("base_qty").item(0).getTextContent());
System.out.println("Var qty : " + eElement.getElementsByTagName("var_qty").item(0).getTextContent());
System.out.println("Base price : " + eElement.getElementsByTagName("base_price_").item(0).getTextContent());
}
在这它只显示第一条记录。我想显示数据库中的所有记录
