Python Selenium获取所有“ href”属性
如何在此页面上获取此“ h2”标题的所有“ href”属性?
<h2 class="entry-title"><a href="http://www.allitebooks.com/deep-learning-with-python-2/" rel="bookmark">Deep Learning with Python</a>
</h2>
我尝试过的没有得到href的是:
title = driver.find_elements_by_class_name('entry-title')title[0].get_attribute('href')
这没有获得“ a”标签的链接。如果我在“ a”标签上找到了所有元素,它将返回页面上的每个href(这不是我想要的)。我只想返回上述标题,但能够获取其url“
href”属性。

这是从所有页面获取所有书籍的代码:
from selenium import webdriverfrom selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
driver = webdriver.Chrome()
baseUrl = "http://www.allitebooks.com/page/1/?s=python"
driver.get(baseUrl)
# wait = WebDriverWait(driver, 5)
# wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, ".search-result-list li")))
# Get last page number
lastPage = int(driver.find_element(By.CSS_SELECTOR, ".pagination a:last-child").text)
# Get all HREFs for the first page and save them in hrefs list
js = 'return [...document.querySelectorAll(".entry-title a")].map(e=>e.href)'
hrefs = driver.execute_script(js)
# Iterate throw all pages and get all HREFs of books
for i in range(2, lastPage):
driver.get("http://www.allitebooks.com/page/" + str(i) + "/?s=python")
hrefs.extend(driver.execute_script(js))
for href in hrefs:
print(href)
