如何从 "Health" 元素中提取文本

How to extract the text from the "Health" Element

我已经尝试了数小时以找到正确的 link 以在 selenium 中用于此游戏的 HP 值。

为了检查您自己,我将提供如下用户名和密码:

Website : https://s3-en.bitefight.gameforge.com/user/login

Username: testaccount111

Password: python123

我试过了health = driver.find_elements_by_xpath("//div[2]/div/div[1]/text()[5]") 但它给出了错误。

使用下面的 xpath 定位您的元素(在图像中标记)

//img[@alt='Health']/preceding-sibling::text()[1]

但是 selenium 不允许您使用文本节点定位元素。另一种方法是您可以使用 javascript 执行程序来评估 xpath。

我在 Java 中有以下代码参考。请根据 python

更改
JavascriptExecutor js = (JavascriptExecutor)driver;
Object health= js.executeScript("var value = document.evaluate(\"//img[@alt='Health']/preceding-sibling::text()[1]\",document, null, XPathResult.STRING_TYPE, null ); return value.stringValue;"); 
System.out.println(health.toString().trim());

WebElement element = driver.findElement(By.xpath("//div[@class='gold']"));
JavascriptExecutor js = (JavascriptExecutor)driver;
String health= (String) js.executeScript("return arguments[0].childNodes[8].textContent", element);
System.out.println(health.trim());

@NarendraR 有很好的答案,在 python 中获得结果的代码 21500

health = driver.execute_script('''
  var value = document.evaluate("//img[@alt='Health']/preceding-sibling::text()[1]",document, null, XPathResult.STRING_TYPE, null );
  return value.stringValue.split('/')[0].trim().replace('.', '');
''');

以及另一种方法

elem = driver.find_element_by_xpath('//div[@class="gold"]')
health = re.search(r'(\d+\.\d+)\s+/', elem.text).group(1)
health = int(health.replace('.', ''))

根据网站 https://s3-en.bitefight.gameforge.com/user/loginHealth 元素中提取文本,即 8.460 / 21.500 您需要诱导 WebDriverWait 使所需的元素可见,您可以使用以下解决方案:

  • 代码块:

    from selenium import webdriver
    from selenium.webdriver.support.ui import WebDriverWait
    from selenium.webdriver.common.by import By
    from selenium.webdriver.support import expected_conditions as EC
    
    options = webdriver.ChromeOptions() 
    options.add_argument("start-maximized")
    options.add_argument('disable-infobars')
    driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
    driver.get("https://s3-en.bitefight.gameforge.com/user/login")
    WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@class='input' and @name='user']"))).send_keys("testaccount111")
    driver.find_element_by_xpath("//input[@class='input' and @name='pass']").send_keys("python123")
    driver.find_element_by_xpath("//input[@class='btn-small' and @value='Login']").click()
    WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//div[@class='gold']//img[contains(@src,'/img/symbols')]")))
    health_text = driver.find_element_by_xpath("//div[@class='gold']").get_attribute("textContent").splitlines()[5]
    print(health_text)
    
  • 控制台输出:

          8.460 / 21.500
