在xml python中查找子元素的子元素

Question

I have an xml file that is containing a root element, and sub elements of sub elements.

For example:

<root>
    <subRoot>
    <Modified name="Set" text="Bla">
      <Action name="Bla2"/>
    </Modified>
</subRoot>
</root>

If i want to delete all of the Action tags under Modified- How can i do that? Thanks.

You can use various libraries, this example is using beautifulsoup :

data = '''<root>
    <subRoot>
    <Modified name="Set" text="Bla">
      <Action name="Bla2"/>
    </Modified>
</subRoot>
</root>'''

from bs4 import BeautifulSoup

soup = BeautifulSoup(data, 'xml')

# selects all tags <Action> under <Modified>
for tag in soup.select('Modified Action'):
    tag.extract() # delete it!

print(soup.prettify())

Prints:

<?xml version="1.0" encoding="utf-8"?>
<root>
 <subRoot>
  <Modified name="Set" text="Bla">
  </Modified>
 </subRoot>
</root>
