python - 使用 Python 解析 XML：将文本保留在属性内，同时删除其周围的标签

问题描述

Input:
<p>
<milestone n="14" unit="verse" />
 The name of the third river is
<placeName key="tgn,1130850" authname="tgn,1130850">Hiddekel</placeName>: this is the one which flows in front of Assyria. The fourth
river is the <placeName key="tgn,1123842" authname="tgn,1123842">Euphrates</placeName>. 
</p>

期望的输出：

<p>
<milestone n="14" unit="verse" />
 The name of the third river is Hiddekel: this is the one which flows in front of Assyria. The fourth river is the Euphrates. 
</p>

您好，我想找到一种方法来从子元素 ( placeName) 中提取文本并将其放回较大的文本正文中。我在 XML 文件的其他地方也有类似的问题，例如人名。我希望能够在不摆脱里程碑的情况下提取名称和地点。谢谢您的帮助！

当前代码：

for p in chapter.findall('p'):
    i = 1
    for text in p.itertext():
        file.write(body.attrib["n"] + " " + chapter.attrib["n"] + ":" +  str(i) + text)
        i = i + 1

解决方案

可以用beautifulsoup和unwrap()方法来完成：

from bs4 import BeautifulSoup as bs

snippet = """your html above"""

soup = bs(snippet,'lxml')
pl = soup.find_all('placename')
for p in pl:
    p.unwrap()
soup

输出：

<html><body><p>
<milestone n="14" unit="verse"></milestone>
 The name of the third river is
Hiddekel: this is the one which flows in front of Assyria. The fourth
river is the Euphrates. 
</p>
</body></html>
