无法使用Java读取XML文档

import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.DocumentBuilder;
import org.w3c.dom.Document;

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();

Document document = builder.parse("path/to/xml/file.xml");

Element rootElement = document.getDocumentElement();

// 示例：获取根元素的子元素列表
NodeList childNodes = rootElement.getChildNodes();
for (int i = 0; i < childNodes.getLength(); i++) {
    Node childNode = childNodes.item(i);
    if (childNode.getNodeType() == Node.ELEMENT_NODE) {
        Element childElement = (Element) childNode;
        // 处理子元素
    }
}
