在Python Selenium中使用变量和跟随兄弟的正确语法是什么? [英] What is the correct syntax for using a variable and following-sibling in Python Selenium?

问题描述

我正在使用Python和Selenium Webdriver.

I'm using Python and Selenium Webdriver.

我有以下代码可以正常工作:

I have the following code which works as expected:

driver.find_element_by_xpath('//p[text()="text"]/../following-sibling::td/div/div/table/tbody/tr/td/a[@class ="class_name"]')

我想将上面的文本"更改为一个变量，类似于以下内容:

I would like to change the above "text" to a variable, similar to the below:

driver.find_element_by_xpath('//p[text()="%s"] % variable_name/../following-sibling::td/div/div/table/tbody/tr/td/a[@class ="class_name"]')

这无效，因为它不是有效的XPath表达式.任何人都可以提供正确的编码帮助吗?

This doesn't work as it isn't a valid XPath express. Can anyone help with the correct coding please?

同样，如果有一种方法可以在后继同级中搜索文本，那也将很有用.类似于:

Also, if there is a way to search for text in the follow-sibling that would also be useful. Something similar to:

 driver.find_element_by_xpath('//p[text()="%s"] % variable_name/../following-sibling:[div@text()= "text"]')

推荐答案

编写'//p[text()="%s"] % variable_name/../following-sibling::td/div/div/table/tbody/tr/td/a[@class ="class_name"]'时，创建了一个字符串，其中字面上包含 %s和% variable_name. %运算符和要替换的变量在字符串文字之外:

When you wrote '//p[text()="%s"] % variable_name/../following-sibling::td/div/div/table/tbody/tr/td/a[@class ="class_name"]', you created a string that literally contains %s and % variable_name. The % operator and the variable(s) to be substituted go outside of the string literal:

'//p[text()="%s"]/../following-sibling::td/div/div/table/tbody/tr/td/a[@class ="class_name"]' % variable_name
