问题 I want to replace all instances of semicolon ":" in my node below with a new node "<colon/>" as shown below.

问题 I am a relative newby to Python and SO. I have an xml file from which I need to extract information. I've been struggling with this for several days, but I think I finally found something that will extract the information properly. Now I'm having troubles getting the right output.

I've looked in the ElementTree documentation & saw the
