您好我正在尝试切换iframe，但我不知道如何将其切换到此框架，因为它的id使用永远动态的yui，目前使用selenium和eclipse luna使用谷歌浏览器作为我的webdriver浏览器
<iframe class="dialog-iframe-node " frameborder="0" id="yui_patched_v3_11_0_1_1436845377989_182_iframe_" name="yui_patched_v3_11_0_1_1436845377989_182_iframe_" src="https://mo-sit.nets.com.sg/group/main/pr-enquiry?p_p_id=p2p_Procurement_Enquiry_WAR_morp2pportlet&p_p_lifecycle=0&p_p_state=pop_up&p_p_mode=view&p_p_col_id=column-1&p_p_col_count=1&_p2p_Procurement_Enquiry_WAR_morp2pportlet_action=renderGRNApplicationsPopup&_p2p_Procurement_Enquiry_WAR_morp2pportlet_appNo=PR020150102506&yui_patched_v3_11_0_1_1436845377989_183=1436845380806" style="height: 351px; width: 1024px;"></iframe>

如果页面上只有一个框架，您可以使用以下代码（在Python上）
driver.switch_to.frame(driver.find_element_by_xpath("//iframe"))
在一般情况下，你应该找到这个框架的一些独特特征，例如，它可以是具有唯一id等的另一个元素的子元素
