python定位

15889369825

<td>xpath=(//a[contains(text(),'编辑')])[15]</td>  selenium录制到的脚本，自己换了好多种定位，都没有定位到“编辑”，求解，新手刚学

<a href="#" class="green-class">编辑</a>这个是网页中看到的

清晨一缕阳光

可以使用classname定位，不过我估计这个页面中叫做"green-class"的会很多，不过可以加个[index]，要地位的是第n个，就填写n-1就可以，数组的下标是从零开的。

童靴，请将问题描述清楚些，起码包含以下的信息：             -
（1）页面相应部分截图 （2）相关脚本 （3）脚本报错信息

driver.find_element_by_css_selector(u"编辑").click()？？？ 这句有问题吧

恩，是有问题，这个是我自己写的，刚开始是这样定位的：driver.find_element_by_xpath(u"(//a[contains(text(),'编辑')])[10]").click()

是有问题，原先是这个driver.find_element_by_xpath(u"(//a[contains(text(),'编辑')])[10]").click()，也会报错，后面换了几种定位，都报错，不知道怎么错了

你把定位编辑的那行代码换成下面这个试试看
driver.find_element_by_class_name("green-class").click()

driver.find_element_by_xpath(u"(//a[contains(text(),'编辑')])[10]").click()

是表达式错了，红色部分总感觉很别扭，具体也不知道哪里错了。

试试修改成：
driver.find_element_by_xpath（//a[@class='green-class']）.click()   (不过前提是这个含class='green-class'的a标签只有一个)
