Selenium/lxml:获取xpath [英] Selenium / lxml : Get xpath

问题描述

是否有 get_xpath 方法或方法可以在 selenium 或 lxml.html 中完成类似的操作.我有种见过面的感觉，但是在文档中找不到类似的东西.

Is there a get_xpath method or a way to accomplish something similar in selenium or lxml.html. I have a feeling that I have seen somewhere but can't find anything like that in the docs.

伪代码说明:

browser.find_element_by_name('search[1]').get_xpath()

>>> '//*[@id="langsAndSearch"]/div[1]/form/input[1]'

推荐答案

由于元素和xpath表达式之间没有唯一的映射，因此不可能采用通用的解决方案.但是，如果您对xml/html有所了解，则可以轻松编写自己的XML/html.只是从您的元素开始，使用 parent 沿着树走，并生成您的表达式.

As there is no unique mapping between an element and an xpath expression, a general solution is not possible. But if you know something about your xml/html, it might be easy to write it your own. Just start with your element, walk up the tree using the parent and generate your expression.
