xpath 相对路径定位取值求助

一、取出：[栏目标识] 下，有：修改按钮 的 第二项名称。
二、然后点击：[栏目标识] 下 第二项名称 后的：修改按钮

xpath 相对路径定位取值求助

代码如下：

其实，你用如果用谷歌，你在当前元素上面，右键（检查），然后在开发工具的当前元素，再右键（COPY/复制），就有XPATH的全路径，或者相对路径，我自己就是这么用废了的

那小子少跟弦

element_1 = document.evaluate("//td[@title='修改按钮']/preceding::td[@title='第二项名称']",document).iterateNext();
element_2 = document.evaluate("./following::td[@title='修改按钮']/button",element_1).iterateNext().click();

补充内容 (2022-7-7 21:51):
没注意是python,我还以为是js..sorry...   直接拿中间的xpath用就好了.一样的

请教：右键：取：相对路径，是哪个选项？我取出来的看着都是全路径。。。

[复制xpath] 就是相对路径
