pylatexen无法分割段落

如何解决pylatexen无法分割段落

我正在使用 pylatexenc 解析 Latex 文档。我没有使用这个包的经验，找到它 here。

我有这个简单的 Latex 文档：

\documentclass{article}

\begin{document}
\title{This is my Latex document}
\author{Gordon Shumway}
\maketitle

\section{Introduction}

First paragraph.

This is a second paragraph in the first section.

\section{Second section}

Many times we have equations like this one 
\begin{equation}
\left(\gamma^{\mu}p_{\mu}-m\right)\left|\psi\right\rangle =0\label{Equation: Dirac}
\end{equation}
 and inline math such as $\psi$. And I can insert a reference to~(\ref{Equation: Dirac}).
\end{document}

可以看出第一节有两段。如果我使用带有以下代码的 pylatexenc 解析文档

from pylatexenc.latexwalker import LatexWalker

with open('latex_document.tex','r') as file:
    latex_file_str = file.read()

w = LatexWalker(latex_file_str)
nodelist,_,_ = w.get_latex_nodes(pos=0)

document = None
for node in nodelist:
    if hasattr(node,'environmentname'):
        if node.environmentname == 'document':
            document = node

for node in document.nodelist:
    print(node,end=4*'\n')
    
document_title = None
for node in document.nodelist:
    if hasattr(node,'macroname'):
        if node.macroname=='title':
            document_title = node
print(f'Title = {document_title.nodeargd.argnlist[0].nodelist[0].chars}')

然而，这两个段落被解析为一个元素：

Bla bla bla...
LatexCharsNode(parsing_state=<parsing state 140254491546672>,pos=134,len=70,chars='\n\nFirst paragraph.\n\nThis is a second paragraph in the first section.\n\n')
Bla bla bla...

我做错了吗？这是意料之中的吗？这是 pylatexenc 的限制吗？
