什么是beautifulsoup
BeautifulSoup是Python中一个用于解析HTML和XML文档的第三方库。使用BeautifulSoup,我们可以方便地从HTML或XML文档中提取出需要的数据。
BeautifulSoup提供了一种类似于面向对象编程的方式来处理文档,我们可以使用tag、string、attribute等属性来搜索文档中的数据。同时,BeautifulSoup还支持CSS选择器、正则表达式等高级搜索技巧,让我们可以更加方便地定位文档中的数据。
在使用BeautifulSoup之前,我们需要安装它的库。可以使用pip命令进行安装:
pip install beautifulsoup4
安装完成后,我们就可以在Python中使用BeautifulSoup库来解析HTML或XML文档,提取出需要的数据了。
