在BeautifulSoup中，使用过滤器进行lxml解析的正确方式是什么？

from bs4 import BeautifulSoup
import requests

url = "http://example.com"  # 替换为实际的URL
response = requests.get(url)
html_content = response.text

soup = BeautifulSoup(html_content, 'lxml')

# 根据标签名获取元素
elements = soup.find_all('tag_name')

# 根据class属性获取元素
elements = soup.find_all(class_='class_name')

# 根据id属性获取元素
elements = soup.find_all(id='id_name')

# 根据属性获取元素
elements = soup.find_all(attrs={'attr_name': 'attr_value'})

import re

# 根据正则表达式匹配元素
pattern = re.compile(r'regex_pattern')
elements = soup.find_all(text=pattern)

for element in elements:
    # 执行操作，如获取文本内容、属性值等
    text = element.get_text()
    attribute = element['attribute_name']
