在Java中使用HtmlUnit抓取(如何查找元素)

WebClient webClient = new WebClient();

HtmlPage page = webClient.getPage("目标网页的URL");

HtmlElement element = page.getFirstByXPath("XPath表达式");

HtmlElement element = page.querySelector("CSS选择器");

String text = element.getTextContent();
String attributeValue = element.getAttribute("属性名");

import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.HtmlElement;
import com.gargoylesoftware.htmlunit.html.HtmlPage;

public class HtmlUnitExample {
    public static void main(String[] args) {
        try (WebClient webClient = new WebClient()) {
            HtmlPage page = webClient.getPage("目标网页的URL");
            HtmlElement element = page.getFirstByXPath("XPath表达式");
            String text = element.getTextContent();
            String attributeValue = element.getAttribute("属性名");
            System.out.println("文本内容：" + text);
            System.out.println("属性值：" + attributeValue);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
