InvalidSelectorException：消息：无效的选择器：指定了无效或非法的选择器，使用 CSSSelector 和 Selenium Python 查找 href
InvalidSelectorException: Message: invalid selector: An invalid or illegal selector was specified finding a href using CSSSelector and Selenium Python
我正在尝试从 中获取 属性“href”，即 "/kkanagas/status/1491996075573587994"。我知道它很长，但我找不到另一种方法来缩短它。只需搜索 "href"，您就会看到 "/kkanagas/status/1491996075573587994" - 这正是我要找的。

这个错误信息...
selenium.common.exceptions.InvalidSelectorException: Message: invalid selector: An invalid or illegal selector was specified
...表示您使用的 定位器策略 无效 .
您需要在 article[data-testid='tweet'] 和 a[href] 之间插入一个 space 以使其成为有效的 。如此有效，您的代码行应该是：
try:
tweets = wait.until(EC.presence_of_all_elements_located(
(By.CSS_SELECTOR, "article[data-testid='tweet'] a[href]")))
links = [link.get_attribute('href')
for link in tweets]
print(links)
except TimeoutException:
print("Couldn't detect any tweets")
但是，要提取 href 属性的 value，即 /kkanagas/status/1491996075573587994 您可以使用以下定位器策略：
try:
tweets = wait.until(EC.presence_of_all_elements_located(
(By.CSS_SELECTOR, "article[data-testid='tweet'] a[href*='status']")))
links = [link.get_attribute('href')
for link in tweets]
print(links)
except TimeoutException:
print("Couldn't detect any tweets")
我正在尝试从 中获取 属性“href”，即 "/kkanagas/status/1491996075573587994"。我知道它很长，但我找不到另一种方法来缩短它。只需搜索 "href"，您就会看到 "/kkanagas/status/1491996075573587994" - 这正是我要找的。

我试图找到它的代码：

(By.CSS_SELECTOR, "article[data-testid='tweet']a[href]")))
links = [link.get_attribute('href')
for link in tweets]
print(links)
except TimeoutException:
print("Couldn't detect any tweets")
错误：

好像哪里不对？
这个错误信息...
selenium.common.exceptions.InvalidSelectorException: Message: invalid selector: An invalid or illegal selector was specified
...表示您使用的 定位器策略 无效
您需要在 article[data-testid='tweet'] 和 a[href] 之间插入一个 space 以使其成为有效的
try:
tweets = wait.until(EC.presence_of_all_elements_located(
(By.CSS_SELECTOR, "article[data-testid='tweet'] a[href]")))
links = [link.get_attribute('href')
for link in tweets]
print(links)
except TimeoutException:
print("Couldn't detect any tweets")
但是，要提取 href 属性的 value，即 /kkanagas/status/1491996075573587994 您可以使用以下定位器策略：
try:
tweets = wait.until(EC.presence_of_all_elements_located(
(By.CSS_SELECTOR, "article[data-testid='tweet'] a[href*='status']")))
links = [link.get_attribute('href')
for link in tweets]
print(links)
except TimeoutException:
print("Couldn't detect any tweets")
