根据html的h1标签和h2标签生成本博客样式的目录

需要为2021年python库大全的post-content代码生成目录

from bs4 import BeautifulSoup

with open('C:/Users/tellw/hexo/source/docs/2021-python-libraries.html',encoding='utf8') as f:
	text=f.read()
soup=BeautifulSoup(text,'html.parser')
h1=soup.find('h1')
print('<div class="post-toc"><ol class="toc">')
print(f'<li class="toc-item toc-level-1"><a class="toc-link" href="#{h1["id"]}"><span class="toc-text">{h1.get_text()[:-1]}</span></a>')
child=False
for h1n in h1.next_siblings:
	if h1n.name=='h1':
		if child:
			print('</ol>')
			child=False
		print(f'</li><li class="toc-item toc-level-1"><a class="toc-link" href="#{h1n["id"]}"><span class="toc-text">{h1n.get_text()[:-1]}</span></a>')
	elif h1n.name=='h2':
		if not child:
			print('<ol class="toc-child">')
			child=True
		print(f'<li class="toc-item toc-level-2"><a class="toc-link" href="#{h1n["id"]}"><span class="toc-text">{h1n.get_text()[:-1]}</span></a></li>')
print('</li></ol></div>')

重点在于next_sibings得到h1和h2列表，并构造树状结构的目录代码
