How To Add A Root To An Existing XML Which Doesn't Have A Single Root Tag

I'm having one XML file which doesn't have a single root tag. I want to add a new Root tag to this XML file. Below is the existing XML: 123 &l

Solution 1:

As pointed out in the comments by @kjhughes, the XML spec requires that a document must have a single root element.

from xml.etree import ElementTree as ET

node = ET.parse(Input_FilePath)
xml.etree.ElementTree.ParseError: junk after document element: line 4, column 0

You'll need to read the file manually and add the tags yourself:

from xml.etree import ElementTree as ET

with open(Input_FilePath) as f:
    xml_string = '<X>' + f.read() + '</X>'

node = ET.fromstring(xml_string)

Solution 2:

I think your can do in without xml parsers. If your know that root tag missing, you can add it by such way.

with open('test.xml', 'r') as f:
    data = f.read()

with open('test.xml', 'w') as f:
    f.write("<x>\n" + data + "\n</x>")
    f.close()

If dont know, your can check it by:

   import re
   if re.match(u"\s*<x>.*</x>", text, re.S) != None:
      #do something   
      pass
