问题
I want to replace all instances of semicolon ":" in my node below with a new node "<colon/>" as shown below.
I want this:
<shortName>Trigger:Digital Edge:Source</shortName>
to become like this:
<shortName>Trigger<colon/>Digital Edge<colon/>Source</shortName>
I have already tried using search and replace string, but when I get the output all the "< >" change to < and > . Can anyone please suggest any techniques to do this. Thank You

The idea is to get the node text, split it by colon and add one by one while setting .tail for every colon:
import xml.etree.ElementTree as ET
data = """<?xml version="1.0" encoding="UTF-8" ?>
<body>
<shortName>Trigger:Digital Edge:Source</shortName>
</body>"""
tree = ET.fromstring(data)
for element in tree.findall('shortName'):
items = element.text.split(':')
if not items:
continue
element.text = items[0]
for item in items[1:]:
colon = ET.Element('colon')
colon.tail = item
element.append(colon)
print ET.tostring(tree)
Prints:
<body>
<shortName>Trigger<colon />Digital Edge<colon />Source</shortName>
</body>
