如何使用 Selenium 和 Python 点击​​链接

Question

您好，我正在尝试使用 selenium 单击此链接，但没有被单击

这是来自网站的 HTML

<td class=" sorting_1" data-key="title" data-label="Title"><a class="document-link" href="/view/html/inforce/current/act-1984-051?query=((Repealed%3DN+AND+PrintType%3D%22act.reprint%22+AND+PitValid%3D%40pointInTime(20190411000000))+OR+(Repealed%3DN+AND+PrintType%3D%22reprint%22+AND+PitValid%3D%40pointInTime(20190411000000)))+AND+Title%3D(%22Aboriginal+and+Torres+Strait+Islander+Communities+(Justice%2C+Land+and+Other+Matters)+Act+1984%22)&amp;dQuery=Document+Types%3D%22%3Cspan+class%3D'dq-highlight'%3EActs%3C%2Fspan%3E%2C+%3Cspan+class%3D'dq-highlight'%3ESL%3C%2Fspan%3E%22%2C+Search+In%3D%22%3Cspan+class%3D'dq-highlight'%3ETitle%3C%2Fspan%3E%22%2C+Exact+Phrase%3D%22%3Cspan+class%3D'dq-highlight'%3EAboriginal+and+Torres+Strait+Islander+Communities+(Justice%2C+Land+and+Other+Matters)+Act+1984%3C%2Fspan%3E%22%2C+Point+In+Time%3D%22%3Cspan+class%3D'dq-highlight'%3E11%2F04%2F2019%3C%2Fspan%3E%22">Aboriginal and Torres Strait Islander Communities (Justice, Land and Other Matters) Act 1984</a></td>

这就是我在我的代码中尝试的内容

act_link = browser.find_element_by_xpath("//a[@class='document-link'][@href]").click()

能否请您检查代码并告诉我我做错了什么？ 这是完整的代码。

            leg_his.click()
        except NoSuchElementException:
            try:    
                act_text = browser.find_element_by_xpath("//div[@id='lhview']/div[@class='content']")
                with open('output.rtf', 'w') as f:
                    f.write(act_text.text)
            except NoSuchElementException:
                time.sleep(10)
browser.back()
time.sleep(10)
browser.quit()

我希望标签 href 链接被点击并移动到下一页。

Answer 1

到click() 元素上的文本为 Aboriginal and Torres Strait Islander Communities (Justice, Land and Other Matters) Act 1984 您需要诱导 WebDriverWait 元素可点击，您可以使用以下任一Locator Strategies：

• 使用LINK_TEXT：

  WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.LINK_TEXT, "Aboriginal and Torres Strait Islander Communities (Justice, Land and Other Matters) Act 1984"))).click()
  

• 使用PARTIAL_LINK_TEXT：

  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.PARTIAL_LINK_TEXT, "Aboriginal and Torres Strait Islander Communities (Justice, Land and Other Matters) Act 1984"))).click()
  

• 使用CSS_SELECTOR：

  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "td.sorting_1[data-key='title'][data-label='Title']>a.document-link[href^='/view/html/inforce/current/act-1984-051']"))).click()
  

• 使用XPATH：

  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//td[@class=' sorting_1' and @data-key='title'][@data-label='Title']/a[@class='document-link' and starts-with(@href, '/view/html/inforce/current/act-1984-051')]"))).click()
  

• 注意：您必须添加以下导入：

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

Answer 2

从您的 Xpath 中删除 [@href]，您需要一个指向 webElement 而不是 webElement 属性的 Xpath。
