问题 Good day! I am currently making a web scraper for Alibaba website. My problem is that the returned source code does not show some parts that I am interested in. The data is there when I checked the source code using the browser, but I can't retrieve it when using BeautifulSoup. Any tips? from bs4 import BeautifulSoup def make_soup(url): try: html = urlopen(url).read() except: return None return BeautifulSoup(html, "lxml") url = "http://www.alibaba.com/Agricultural-Growing-Media_pid144" soup2

问题 I'm trying to scrape a table from a dynamic page. After the following code (requires selenium), I manage to get the contents of the <table> elements. I'd like to convert this table into a csv and I have tried 2 things, but both fail: pandas.read_html returns an error saying I don't have html5lib installed, but I do and in fact I can import it without problems. soup.find_all('tr') returns an error 'NoneType' object is not callable after I run soup = BeautifulSoup(tablehtml) Here is my code:

问题 I am trying to learn to use the python library BeautifulSoup, I would like to, for example, scrape a price of a flight on Google Flights. So I connected to Google Flights, for example at this link, and I want to get the cheapest flight price. So I would get the value inside the div with this class "gws-flights-results__itinerary-price" (as in the figure).

如何利用BeautifulSoup选择器抓取京东网商品信息

由 佐手、 提交于 2020-08-19 03:19:56
昨天小编利用Python正则表达式爬取了京东网商品信息，看过代码的小伙伴们基本上都坐不住了，辣么多的规则和辣么长的代码，悲伤辣么大，实在是受不鸟了。不过小伙伴们不用担心，今天小编利用美丽的汤来为大家演示一下如何实现京东商品信息的精准匹配~~ HTML文件其实就是由一组尖括号构成的标签组织起来的，每一对尖括号形式一个标签，标签之间存在上下关系，形成标签树；因此可以说Beautiful Soup库是解析、遍历、维护“标签树”的功能库。 首先进入京东网，输入自己想要查询的商品，向服务器发送网页请求。在这里小编仍以关键词“狗粮”作为搜索对象，之后得到后面这一串网址： https://search.jd.com/Search?keyword=%E7%8B%97%E7%B2%AE&enc=utf-8 ，其中参数的意思就是我们输入的keyword，在本例中该参数代表“狗粮”，具体详情可以参考 Python大神用正则表达式教你搞定京东商品信息 。所以，只要输入keyword这个参数之后，将其进行编码，就可以获取到目标URL。之后请求网页，得到响应，尔后利用bs4选择器进行下一步的数据采集。 商品信息在京东官网上的部分网页源码如下图所示： 仔细观察源码，可以发现我们所需的目标信息是存在 标签下的，那么接下来我们就像剥洋葱一样，一层一层的去获取我们想要的信息。 直接上代码，如下图所示：

Python网络爬虫项目：使用requests获取网页，通过BeautifulSoup提取数据

本次讲解通过requests获取某一个网站，网址：http://www.gxccedu.com/sp2017/zli/index.html 然后使用正则表达式提取页面中的“专利名称”。 步骤： 1、使用pycharm新建项目，新建的时候记得勾选“Inherit global site-packages”否则可能找不到requests类库 2、编写代码，我们看到网页上的数据量是101行，如下所示： 代码如下： 项目结构（不重要）： 程序代码： Beautiful Soup可以将HTML文档转换为Tag树形结构，如果BeautifulSoup对象是soup,则我们可以通过soup.td获取页面里面的第一个td元素，通过soup.find_all('td')获取所有的td元素。也就是find_all()返回来的是一个数组元素，那么我们可以通过下标来获取对应的内容，如下： 我们可以看到，第一个专利的名称的下标是7，第二个是13，第三个是19，依次类推，所以我们可以通过间隔获取的方式来达到效果。 代码如下，另外要记得最后获取的是text属性，否则获取的就是是<td>XXX</td>的内容： 运行效果： 来源： oschina 链接： https://my.oschina.net/u/4082616/blog/4313096
