Example 1
此示例使用了带以下脚本的网页 index.html
A web page index.html with following script has been used for this example
<html>
<head>
<title>TutorialsPoint</title>
</head>
<body>
<h1>TutorialsPoint</h1>
<form>
<input type = 'text' id = 'nm' name = 'name'>
<input type = 'text' id = 'age' name = 'age'>
<input type = 'text' id = 'marks' name = 'marks'>
</form>
</body>
</html>我们首先找到 <form> 标签，然后再找到其旁边的标签。
We first locate the <form> tag and then the one next to it.
from bs4 import BeautifulSoup
fp = open("index.html")
soup = BeautifulSoup(fp, 'html.parser')
tag = soup.h1
print (tag.find_next())Output
<form>
<input id="nm" name="name" type="text"/>
<input id="age" name="age" type="text"/>
<input id="marks" name="marks" type="text"/>
</form>Example 2
在这个示例中，我们首先找到 name='age' 的 <input> 标签，然后获取其下一个标签。
In this example, we first locate the <input> tag with its name='age' and obtain its next tag.
from bs4 import BeautifulSoup
fp = open("index.html")
soup = BeautifulSoup(fp, 'html.parser')
tag = soup.find('input', {'name':'age'})
print (tag.find_next())
