[Python] Python editing file in loop, how to keep changes after each (xml)

I need to clean few xml files from not needed elements, came up with this wild card replacement for nothing to get rid of not needed <EmbeddedImage>, but I'm missing how to store each change in the loop, looks like it overwrites it each time. Thought that Python will keep it, but it's not the case. Do I need to create some additional logic to get only single Brand_1 in my final tree?

Appreciate if you point me how I can fix it.

import re
from bs4 import BeautifulSoup as bs
filepath = "C://ddd/test.xml"

xml = '''
<Images>
<EmbeddedImage Name="Brand_1">
<ImageData>/9j/4AAQSkZJB//2Q==</ImageData>
</EmbeddedImage>
<EmbeddedImage Name="Brand__2XX">
<ImageData>/9j/4AAQSkZJB//2Q==JB//2</ImageData>
</EmbeddedImage>
<EmbeddedImage Name="Brand___3XX">
<ImageData>/9j/4AAQSkZAAQSkkB//2Q=AAQSk=</ImageData>
</EmbeddedImage>
<Images>'''

Bs_data = bs(xml,'xml') #contant = xml ??
content = xml
for item in Bs_data.select ('EmbeddedImage'):
#print('Name= ',item.get('Name'))
if item.get('Name') != 'Brand_1':
wild = '<EmbeddedImage Name="'+item.get('Name')+'">.*</EmbeddedImage>' ##<@><< first </ How???
content = re.sub(wild, '', content , flags=re.DOTALL)
print ('------------',wild,'::::',content)

print(content) # only Brand_1
