如何为软件找到正确的cssselector或标签 [英] How do I find the correct cssselector or tag for the software

问题描述

基本信息

我有这个软件，我正在为个人使用而开发，因为我正在使用它作为学习Selenium的一种方式（通过反复试验和迄今为止）我知道基础知识，因为我已经完成了它）

软件的功能

它将分析从网站列表中排名前5位最活跃的股票并将其打印到软件上（很简单吧？）

问题

此刻我已经做到了这一点，它取了一个名字&这个网站上列表中的顶级项目的百分比（曾经是最重要的一个），但随后它变为第三个，当我实际按下按钮时它的作用是（正如我刚才解释的那样）它拉出了第三个选项曾经是第一个的那个

我想做什么

我需要正确的TagName或CssSelector，它显示1-5列表中的最新情况如果它改变了，我希望它在网站改变时改变

示例

我按下按钮（label11_Click）（对不起我的命名不好）

它显示前5项

我关闭应用程序并等待24小时

网站上的列表更改

我24小时后重新打开申请

我按下相同的按钮（label11_Click）

它显示新的前5项

我的代码

Basic Information

I have this software that I am developing for my personal use because im using it as a way to learn Selenium (By trial and error and so far I know the basics because I already went through it)

What the software does

It will analyze the top 5 most active stocks from a list on the website and print it out on to the software (Pretty simple right?)

The Issue

At this moment I've made it so it pulls a name & the percentage of top item from the list on this website (which used to be the top one) but then it changed to the 3rd one and what it does when I actually press the button is (as I just explained) it pulls the third option which is the one that used to be the first one

What I WOULD like it to do

I would need the correct TagName or the CssSelector which shows whats in the list from 1-5 EVEN if it changes, I would like it to change when the website changes

Example

I press the button (label11_Click) (Sorry for the bad naming on my part)
It shows the top 5 items
I close the app and wait 24 hours
The list changes on the website
I reopen the application after 24 hours
I press the same button (label11_Click)
it shows the new top 5 items

My Work At the moment

我尝试过：



我是尝试更改CssSelector，但它或者给了我一个错误或根本没有做任何事情，我认为我使用错误的方式。

What I have tried:

I've tried changing the CssSelector but it either gave me an error or didnt do anything at all, I think im using them the wrong way.

推荐答案

当试图使用selenium时掌握Xpath非常重要。如果您不是使用css选择器搜索xpath，您可以尝试这样的事情：

// div [@ id ='market-summary-body'] / div [2] / div [@ class ='pages'] / div / div / table / tbody / tr

我在谷歌浏览器中测试的将为您提供所有顶级活动行的列表。

When trying to use selenium it is important to get a grasp on Xpath. If instead of using the css selector you search by xpath you can try something like this:
//div[@id='market-summary-body']/div[2]/div[@class='pages']/div/div/table/tbody/tr
Which I tested in google chrome will get you a list of all the top active rows.
