爲Python硒選擇元素我有這樣的HTML片段:InvalidSelectorException當使用XPath
<div class="btn">
<a href="javascript:void(0)" class="S_btn_b" node-type="OK">
<span>確定</span>
</a>
</div>
我要選擇確定
元素並單擊它。我試着用xpath以下選擇:
confirm_btn = driver.find_element_by_xpath('//div[@class="btn"]//span[text()="確定"]')
但該方案只是抱怨,是不是與此異常有效的選擇:
Traceback (most recent call last):
File "test.py", line 63, in <module>
ac.move_to_element(driver.find_element_by_xpath('//div[@class="btn"]/span[text()="確定"'))
File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 230, in find_element_by_xpath
return self.find_element(by=By.XPATH, value=xpath)
File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 662, in find_element
{'using': by, 'value': value})['value']

File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/errorhandler.py", line 166, in check_response
raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.InvalidSelectorException
難道我做錯了什麼?
如果只用''// div [@ class =「btn」] // span''嘗試會發生什麼? – 2015-02-10 11:02:33
@MathiasMüller似乎沒有指定'span'的'text()'可能是引號出現問題嗎? – armnotstrong 2015-02-10 11:10:14
不,但似乎不支持這些字符(中文?)。 – 2015-02-10 11:12:12
