我想通过点击相关链接导航到 /yandsearch?... . 页面中有两个链接：
<a class="button button_theme_pseudo button_pseudo-pressed_yes button_size_m button_counter_yes button_focus_no b-link b-link_pseudo_yes pager__button pager__button_kind_page i-bem button_js_inited" onmousedown="w(this, '405.88');" href="/yandsearch?lr=157&text=landsad&p=3" role="button" ondblclick="return {"button":{"counter":"w(this, '405.88');"},"b-link":{}}">

我收到错误：
raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.InvalidSelectorException: Message: 'The given selecto......
我想点击此链接第4页yandex.by/yandsearch
我也试过了：
//*[contains(@href,"yandsearch?lr=157&text=landsad&p=3") and contains(@class,"button_js_inited")]
写错误：
self.error_handler.check_response(response) File "C:\Python34\lib\site- packages\selenium\webdriver\remote\errorhandler.py" ,
line 164, in check_response raise exception_class(message, screen, stacktrace) selenium.common.exceptions.NoSuchElementException:

您的XPath无效，两个条件都应放在相同的方括号内（格式为readiblity）：
