How To Change Different Hierarchy Tags With Lxml?

I want to change all tags names

to using lxml in python. The problem is I'm able to change the outer concept tag's

tag and the first inner con

Solution 1:

I think you're overcomplicating it. Just find all of the p elements (with .xpath() or .findall()) and change the value of the .tag property...

from lxml import etree

tree = etree.parse("73-20.xml")

for p in tree.findall(".//p"):
    p.tag = "paragraph"

tree.write("FerNewtags.xml")

Output (FerNewtags.xml)
