XML Response in Python

Writing an XML response doc in python is pretty easy.
While working on one of the projects i wrote some
methods thats make it even easy to use:

import xml.dom.minidom

class MyXml:
    def __init__(self):
        self.doc = xml.dom.minidom.Document()

    def add_root(self, node_str):
        """creates and returns root node"""
        root = self.doc.createElementNS("", node_str)
        return root       

    def add_node(self, node, node_str):
        """creates and returns a child node"""
        ch_node = self.doc.createElementNS("", node_str)
        return root
    def add_txt_value(self, node, value):
        """creates a text node and appends to existing node"""
        txt_node = self.doc.createTextNode(str(value))

# example to create a xml response document you can simply add nodes and text
#as given below
#<?xml version="1.0" encoding="utf-8"?>
# <response>
#       <success> Hey i got your msg</success>
# </response>

if __name__ == '__main__':
    xmlObj = MyXml()
    #to create root node
    root = xmlObj.add_root("response")
    #to add child node arg1 parent node, arg2 child node
    node1 = xmlObj.add_node(root, "success")
    #to add success string to success node
    xmlObj.add_txt_value(node1, "Hey i got your msg")
