如果在使用BeautifulSoup解析HTML时,打印出的结果包含空元素,可以通过以下步骤解决该问题:
1.使用find_all()方法筛选出所有非空的元素
2.使用标准异常处理机制来处理空元素,并在程序中设定处理空元素的方法
下面是一个简单的示例:
from bs4 import BeautifulSoup
html_doc = """
The Dormouse's story
Once upon a time there were three little sisters; and their names were Elsie, Lacie and Tillie; and they lived at the bottom of a well.
...
"""soup = BeautifulSoup(html_doc, 'html.parser')
for element in soup.find_all(): try: print(element) except Exception as e: pass
在上面的例子中,使用try-except结构来将空元素跳过并继续执行,可以使程序更稳健。
