Python selenium 从文本区域获取文本

Question

我正在尝试将文本区域消息复制到一个变量中，以便我可以解析它。

正文区有留言如下：

<?xml version='1.0' encoding='UTF-8'?><Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/"><Body><SubmitResponse xmlns="http://eftr</Error></SubmitResponse></Body></Envelope>

HTML如下：

<textarea class="v-textarea v-widget v-readonly v-has-width v-has-height v-textarea-readonly" rows="5" tabindex="-1" readonly="" style="width: 100%; height: 100%;"></textarea>

我正在尝试以下配置和其他配置，但没有成功：

from selenium import webdriver
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
full_xpath = r'/html/body/div[1]/div/div[2]/div/div[2]/div/div[2]/div/div/div[3]/div/div/div[2]/div/div[2]/div/div/div/div/div[3]/textarea'
path_to_chromedriver = r'C:\chromedriver'  # change path as needed
browser = webdriver.Chrome(executable_path=path_to_chromedriver)
.........
.........
content = browser.find_element_by_xpath(full_xpath).text

我不确定如何实现上述目标。

基本上 print(content) 应该产生以下结果：

<?xml version='1.0' encoding='UTF-8'?><Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/"><Body><SubmitResponse xmlns="http://eftr</Error></SubmitResponse></Body></Envelope>

Answer 1

使用以下 xpath 来识别元素。

content = browser.find_element_by_xpath("//textarea[@class='v-textarea v-widget v-readonly v-has-width v-has-height v-textarea-readonly']").text

或使用get_attribute("innerHTML")

content = browser.find_element_by_xpath("//textarea[@class='v-textarea v-widget v-readonly v-has-width v-has-height v-textarea-readonly']").get_attribute("innerHTML")

我建议使用 WebDriverWait() 并等待 visibility_of_element_located()

content=WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//textarea[@class='v-textarea v-widget v-readonly v-has-width v-has-height v-textarea-readonly']"))).text

您需要导入以下库

from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

Answer 2

from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

textcontent=WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//textarea[@class='v-textarea v-widget v-readonly v-has-width v-has-height v-textarea-readonly']"))).get_attribute("value")

在文本区域中，文本存储为值，

示例文本区域：

<!DOCTYPE html>
<html>
<body>

<h1>The textarea element</h1>

<form action="/action_page.php">
<label for="w3review">Review of W3Schools:</label>
<textarea id="w3review" name="w3review" rows="4" cols="50">
  At w3schools.com you will learn how to make a website. They offer free tutorials in all web development technologies.
  </textarea>
  <br><br>
  <input type="submit" value="Submit">
</form>

<p>Click the "Submit" button and the form-data will be sent to a page on the 
server called "action_page.php".</p>
</body>
</html>

您可以使用上面的示例 html 并在控制台中尝试

   $('textarea').value
