按多个类的HREF属性查找页面上的元素

Question

我正在使用Selenium库和python。 在页面上，我得到了多个报价，每个报价都有相同的链接开头https://www.example.com/offer/。。。。 和相同的类，但问题是我找不到包含多个类的元素。它还具有相同的属性“data cy”

我试过了

offerName = driver.find_element_by_xpath("//a[contains(@class, 'marginright5') and contains(@class, 'link') and contains(@class, 'linkWithHash') and contains('detailsLink')]")

但由于这个错误，它不起作用

selenium.common.exceptions.InvalidSelectorException: Message: Given xpath expression "//a[contains(@class, 'marginright5') and contains(@class, 'link') and contains(@class, 'linkWithHash') and contains('detailsLink')]" is invalid: [Exception... "<no message>"  nsresult: "0x8060000d (<unknown>)"  location: "JS frame :: chrome://marionette/content/element.js :: element.findByXPath :: line 387"  data: no]

我怎样才能找到他们

Answer 1

就像错误消息说xpath无效一样， 我可以在最后一个“contains”中看到一个错误

尝试更改此选项：

driver.find_element_by_xpath("//a[contains(@class, 'marginright5') and contains(@class, 'link') and contains(@class, 'linkWithHash') and contains('detailsLink')]"

为此：

driver.find_element_by_xpath("//a[contains(@class, 'marginright5') and contains(@class, 'link') and contains(@class, 'linkWithHash') and contains(@class, 'detailsLink')]"
