是否删除子标记，但将文本保留为xml格式？

Question

我有一个xml，看起来像这样

<?xml version='1.0' encoding='utf8'?>
<all>
<articletitle>text1<x> </x></articletitle>
<affiliation><x> </x><label id="aff1">12</label><affnorg>College of Materials Science and Engineering</affnorg><x>, </x><affnorg>Guangdong Research Center for Interfacial Engineering of Functional Materials</affnorg><x>, </x><affnorg>Shenzhen University</affnorg><x>, </x><affnadd>3688 Nanhai Ave</affnadd><x>, </x><affncity>Shenzhen</affncity><x>, </x><affnpost>518060</affnpost><x>, </x><affncountry>PR China</affncountry><x>.</x></affiliation>
<affiliation><x> </x><label id="aff2">2</label><affnorg>Key Laboratory of Optoelectronic Devices and Systems of Ministry of Education and Guangdong Province</affnorg><x>, </x><affnorg>College of Optoelectronic Engineering</affnorg><x>, </x><affnorg>Shenzhen University</affnorg><x>, </x><affnadd>3688 Nanhai Ave</affnadd><x>, </x><affncity>Shenzhen</affncity><x>, </x><affnpost>518060</affnpost><x>, </x><affncountry>PR China</affncountry><x>.</x></affiliation>
</all>

任务是，我必须删除所有的<x>标记，并仅在affiliation标记中保留它们的文本，使用ElementTree我可以删除标记，但它也会删除文本，但我希望该文本位于父标记中，因此我的新xml如下所示

<?xml version='1.0' encoding='utf8'?>
<all>
<articletitle>text1<x> </x></articletitle>
<affiliation> <label id="aff1">12</label><affnorg>College of Materials Science and Engineering</affnorg>, <affnorg>Guangdong Research Center for Interfacial Engineering of Functional Materials</affnorg>, <affnorg>Shenzhen University</affnorg>, <affnadd>3688 Nanhai Ave</affnadd>, <affncity>Shenzhen</affncity>, <affnpost>518060</affnpost>, <affncountry>PR China</affncountry>.</affiliation>
<affiliation> <label id="aff2">2</label><affnorg>Key Laboratory of Optoelectronic Devices and Systems of Ministry of Education and Guangdong Province</affnorg>, <affnorg>College of Optoelectronic Engineering</affnorg>, <affnorg>Shenzhen University</affnorg>, <affnadd>3688 Nanhai Ave</affnadd>, <affncity>Shenzhen</affncity>, <affnpost>518060</affnpost>, <affncountry>PR China</affncountry>.</affiliation>
</all>

Answer 1

使用BeautifulSoup可以使用unwrap()函数：

data = '''<?xml version='1.0' encoding='utf8'?>
<all>
<articletitle>text1<x> </x></articletitle>
<affiliation><x> </x><label id="aff1">12</label><affnorg>College of Materials Science and Engineering</affnorg><x>, </x><affnorg>Guangdong Research Center for Interfacial Engineering of Functional Materials</affnorg><x>, </x><affnorg>Shenzhen University</affnorg><x>, </x><affnadd>3688 Nanhai Ave</affnadd><x>, </x><affncity>Shenzhen</affncity><x>, </x><affnpost>518060</affnpost><x>, </x><affncountry>PR China</affncountry><x>.</x></affiliation>
<affiliation><x> </x><label id="aff2">2</label><affnorg>Key Laboratory of Optoelectronic Devices and Systems of Ministry of Education and Guangdong Province</affnorg><x>, </x><affnorg>College of Optoelectronic Engineering</affnorg><x>, </x><affnorg>Shenzhen University</affnorg><x>, </x><affnadd>3688 Nanhai Ave</affnadd><x>, </x><affncity>Shenzhen</affncity><x>, </x><affnpost>518060</affnpost><x>, </x><affncountry>PR China</affncountry><x>.</x></affiliation>
</all>'''

from bs4 import BeautifulSoup

soup = BeautifulSoup(data,'xml')

for x in soup.select('affiliation x'):
    x.unwrap()

print(soup)

印刷品：
