lxml.html我认为，使用解析注释的内容是一个很好的解决方案。
Python代码
from lxml import etree
from io import StringIO
parser = etree.HTMLParser()
html_text = """<div>
<tr id="1"></tr>
<tr id="2">
<!--
<div class="A">AAA</div>
<div class="C">BBB</div>
<div class="C">CCC</div>
-->
</tr>
</div>"""
tree = etree.parse(StringIO(html_text), parser)
comment = tree.xpath("//tr[@id='2']/comment()")
comment_text = str(comment[0])
# string needs an outermost element in order to be parseable
comment_text = comment_text.replace("<!--", "<html>").replace("-->", "</html>")
embedded_tree = etree.parse(StringIO(comment_text), parser)
embedded_tree.xpath("//div[@class='C']/text()")
输出量
['BBB', 'CCC']

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.
