我正在尝试捕获所附文本的脚注。因此，逻辑是脚注以换行符上的数字开头(nd+s)并以换行符上的数字(nd+s)或单词"Page"结尾。该逻辑似乎适用于多个在线正则表达式测试器，但返回一堆空字符串作为谷歌 colab 中 python 脚本的输出。
这是代码：
m=re.findall('nd+(?:(?!nd+s)(?!Page)(.|n))*', text)
输出是空字符串列表
下面是两个文本示例：
However, we also urge the Commission to go further, and revisit the entire NMS Plan
process -- which is fundamentally conflicted and severely outdated.3 The NMS Plan
process was devised over forty years ago at a time of fewer exchanges that were also
mutually owned, not-for-profit entities. In stark contrast, today, these entities are
for-profit publicly traded entities with third-party shareholders. While the proposed
reforms would assert the Commission’s ability to more effectively regulate NMS Plan
fee filings, it would not directly address the conflicts of interest of having for-profit
entities acting as both regulators and fee setters on essential capital market utilities. We
ask the Commission to boldly address these bigger issues, and to the extent necessary,
seek assistance from Congress.

Background on NMS Plans Generally
In the early 1970s, it became clear that the government needed to step into the markets
to provide a mechanism to consolidate information and accountability across a myriad
of trading venue. The Commission began outlining the contours of a “central market
system for listed securities.”4
The Commission has asked whether, as an alternative to rescinding the Fee Exception and
instating the standard procedure, it should consider permitting NMS plan fee applications to
take effect 60 days after filing if the Commission does not act. In our view, this approach –
while preferable to the current Fee Exception – essentially establishes a Fee Exception by
another name. As is the case under the current Fee Exception, the alternative, 60-day

10 Proposal at 38.

process, as described by the Commission, would still allow a fee change to take effect without
an affirmative determination by the Commission during the 60-day abrogation period that the
fee change comports with the requirements of the Exchange Act. More fundamentally, the
Commission has taken notice of the fact that NMS plan fees are not economically de minimis
or otherwise trivial; to the contrary, the total revenues generated by fees for core data totaled
more than $500 million in just 2017. Given that fact alone, we are hard-pressed to understand
why fee-related applications should be subject to a lesser standard of review than applications
that pertain to other matters and that may be less significant economically to investors and
other market participants.
在第二个输出中，我们期望的输出是：m=['9 Proposal at 17.', '10 Proposal at 38.']
总之，列表m中的每个项目都应该是一个单独的脚注。我们应该如何使用 python 在谷歌 colab 中使用正则表达式来解决这个问题
当您在正则表达式中的捕获组周围加上括号时，我会工作：
m=re.findall('(nd+s(?:(?!nd+s)(?!Page)(.|n))*)', text)
