How to replace DOCTYPE element in Python?

My input file is:

<?xml version="1.0" encoding="utf-8"?> <!DOCTYPE note SYSTEM "Note.dtd"> <book> <name>ABC</name> </book>

I want to change the DOCTYPE element (commented - see below):

DOCTYPE

<?xml version="1.0" encoding="utf-8"?>  <book> <name>ABC</name> </book>

I wonder if we can do xml manipulation. Here what you can do with string manipulation

a='''<?xml version="1.0" encoding="utf-8"?> <!DOCTYPE note SYSTEM "Note.dtd"> <book> <name>ABC</name> </book>''' lis=a.split('n') for i,j in zip(lis,range(len(lis))): if i.startswith('<!DOCTYPE'): i = '' lis[j]=i a='n'.join(lis)

If it does not have anything to split on.

a='<?xml version="1.0" encoding="utf-8"?><!DOCTYPE note SYSTEM "Note.dtd"><book><name>ABC</name></book>' str1="" start=a.index('<!DOCTYPE') end=a.index('>',start) str1=a[:start] str1+='' str1+=a[end+1:] str1 #'<?xml version="1.0" encoding="utf-8"?><book><name>ABC</name></book>'

Your answer is work correctly but you know that I want to change doctype element if doctyoe element is coming in third line than your code is fail.

Then split by space if it is really an xml. Otherwise, edit the question with all the possibilities.

Check this code. <?xml version="1.0" encoding="utf-8"?><!DOCTYPE note SYSTEM "Note.dtd"><book><name>ABC</name></book>
