解析XML文件时，Java异常处理示例

在Java中解析XML文件时，可能会遇到一些异常。以下是一个简单的异常处理示例：

import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.NodeList;
import java.io.File;
import java.io.IOException;
public class XMLParserExample {
    public static void main(String[] args) {
        File xmlFile = new File("path_to_your_xml_file.xml");
        try {
            // Create a DocumentBuilderFactory
            DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
            // Parse with factory, catches exceptions
            Document doc = dbFactory.newDocumentBuilder().parse(xmlFile);
            // Access XML elements and attributes
            Element rootElement = doc.getDocumentElement();
            System.out.println("Root element: " + rootElement.getTagName());
            NodeList nodeList = rootElement.getChildNodes();
            for (int i = 0; i < nodeList.getLength(); i++) {
                Node node = nodeList.item(i);
                if (node instanceof Element) {
                    System.out.println("Child element: " + node.getTagName());
                }
            }
        } catch (ParserConfigurationException | IOException | IllegalArgumentException e) {
            // Handle exceptions
            System.err.println("Error parsing XML file: " + e.getMessage());
        }
    }
}
