如何解决如何找到该网站的xpath表达式？

我要剪贴此网页。

我有很多简历，我的任务是收集每一份简历的技能。 这是网页的链接==> https://www.livecareer.com/resume-search/search?jt=software%20engineer

解决方法

实际上，这里不需要使用strsplit。您可以使用result <- do.call(rbind,strsplit(df$COL1,'(_)(?!.*_)',perl = TRUE)) 轻松地做到这一点。这是完整的代码：

selenium

输出：

BeautifulSoup

U还可通过将以下几行添加到您的代码中来创建漂亮的import requests from bs4 import BeautifulSoup r = requests.get('https://www.livecareer.com/resume-search/search?jt=software%20engineer').text soup = BeautifulSoup(r,'html.parser') ul = soup.find('ul',class_ = 'resume-list list-unstyled') li_items = ul.find_all('li')[1:] links = [] for li in li_items: links.append('https://www.livecareer.com/'+li.a['href']) skills = [] for link in links: r = requests.get(link).text soup = BeautifulSoup(r,'html.parser') div = soup.find('div',class_ = 'field singlecolumn') skills.append(div.text) print(skills) （以提高可读性）：

您可以使用浏览器的开发人员工具查找任何html元素的XPath。以下示例适用于Chrome浏览器，但是其他浏览器的操作步骤非常相似：

1. 右键单击页面上您想要了解XPath的项目。
2. 单击“检查”。这将打开“开发工具”，并突出显示有问题的元素。
3. 如果您要查找的元素不是突出显示的元素，请在显示的交互式html中导航。通常，当您将鼠标悬停在某个元素上时，匹配项就会在主页上突出显示。
4. 右键单击导航器中的html元素。
5. 选择“复制->复制XPath”。

在抓取这些页面时可能遇到的主要问题是，目标可能每次都不在同一位置。如果这些是用户创建的文档，则它们可能每次都有不同的布局，因此XPath可能与每个页面上的同一部分都不匹配。如果是这种情况，您可能需要执行更复杂的方法（jQuery，Selenium，Cypress等都具有用于按文本内容搜索，在父/子元素之间导航的工具）。

要把它扔在那里。....

如前所述，二手铬 右键单击所需的元素 点击检查 按ctrl + f打开搜索窗口

然后编写您的xpath，使其返回一个（并且只有一个）页面对象。

例如：

//a[contains(text(),'my text')] 
//div[@id='myDivID']

创建项目的xpath。从未使用过“复制Xpath”选项。您将获得如下所示的路径，这是您可以编写的最易碎的xpath。

//*[@id="wrapper"]/div[2]/div[2]/div[1]/aside[1]/div/div/div[2]/div/div[1]/a

如果您不熟悉编写xpath，请转到此处阅读https://www.w3schools.com/xml/xpath_intro.asp

您在这里遇到的一个问题是，文本位于div标记内，并且实际上应该在范围内。您可以尝试以下操作：

//div[@class='field singlecolumn']/text()
