对于 XML 关键字搜索项目,用户可以搜索 XML 代码中的任何值:
<?xml version="1.0" encoding="UTF-8"?>
<company>
<staff id="1001">
<firstname>sachin</firstname>
<lastname>tendulkar</lastname>
<nickname>TON</nickname>
<salary>100000</salary>
</staff>
<staff id="2001">
<firstname>MS</firstname>
<lastname>Dhoni</lastname>
<nickname>MSD</nickname>
<salary>200000</salary>
</staff>
<staff id="3001">
<firstname>yuraj</firstname>
<lastname>singh</lastname>
<nickname>yuvi</nickname>
<salary>200000</salary>
</staff>
</company>
如果用户搜索20000
,结果将在 ID 中可用,1001
因此2001
输出应如下所示:
ms
dhoni
msd
200000
yuraj
singh
yuvi
20000
我想在Java中做到这一点。这是我到目前为止所写的:
package a;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.DocumentBuilder;
import org.w3c.dom.Document;
import org.w3c.dom.NodeList;
import org.w3c.dom.Node;
import org.w3c.dom.Element;
import java.io.File;
public class TestJava
{
public static void TestJava(String s) {
try {
File fXmlFile = new File("E:/xml/xml/src/a/test.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("staff");
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;
if(eElement.getElementsByTagName("salary").item(0).getTextContent().equals(s))
{
System.out.println("Staff id : " + eElement.getAttribute("id"));
System.out.println("First Name : " + eElement.getElementsByTagName("firstname").item(0).getTextContent());
System.out.println("Last Name : " + eElement.getElementsByTagName("lastname").item(0).getTextContent());
System.out.println("Nick Name : " + eElement.getElementsByTagName("nickname").item(0).getTextContent());
System.out.println("Salary : " + eElement.getElementsByTagName("salary").item(0).getTextContent());
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
