需要使用RegEx和BeautifulSoup查找文本 [英] Need to find text with RegEx and BeautifulSoup
问题描述
我正试图解析一个网站，以提取出一些存储在主体中的数据，例如:
I'm trying to parse a website to pull out some data that is stored in the body such as this:
<body>
<b>INFORMATION</b>
Hookups: None
Group Sites: No
Station: No
<b>Details</b>
Ramp: Yes
</body>
我想使用BeautifulSoup4和RegEx提取连接和组站点等的值，但是我对bs4和RegEx还是陌生的.我已经尝试了以下方法来获取联播网值:
I would like to use BeautifulSoup4 and RegEx to pull out the values for Hookups and Group Sites and so on, but I am new to both bs4 and RegEx. I have tried the following to get the Hookups Value:
soup = BeautifulSoup(open('doc.html'))
hookups = soup.find_all(re.compile("Hookups:(.*)Group"))
但是搜索返回为空.
推荐答案
BeautifulSoup的find_all仅适用于标签.假设HTML如此简单，您实际上可以仅使用纯正则表达式来获得所需的内容.否则，您可以使用find_all，然后获取.text节点.
BeautifulSoup's find_all only works with tags. You can actually use just a pure regex to get what you need assuming the HTML is this simple. Otherwise you can use find_all and then get the .text nodes.
re.findall("Hookups: (.*)", open('doc.html').read())
从BeautifulSoup 4.2开始，您还可以使用text属性按标签内容进行搜索
You can also search by tag content with the text property as of BeautifulSoup 4.2
soup.find_all(text=re.compile("Hookups:(.*)Group"));
