Understanding how to quote XML string in order to serialize using Python's ElementTree

[kbtyo]

My specs:

Python 3.4.3
Windows 7
IDE is Jupyter Notebooks

Here is the data (in CSV format) and script, respectively, (I have tried variations on serializing Column 'E' using both Sax and ElementTree):

i)

A,B,C,D,E,F,G,H,I,J
"3","8","1","<Request TransactionID="3" RequestType="FOO"><InstitutionISO /><CallID>23</CallID><MemberID>12</MemberID><MemberPassword /><RequestData><AccountNumber>2</AccountNumber><AccountSuffix>85</AccountSuffix><AccountType>S</AccountType><MPIAcctType>Checking</MPIAcctType><TransactionCount>10</TransactionCount></RequestData></Request>","<Response TransactionID="2" RequestType="HoldInquiry"><ShareList>0000',0001,0070,</ShareList></Response>","1967-12-25 22:18:13.471000","2005-12-25 22:18:13.768000","2","70","0"

ii)

#!/usr/bin/python
# -*-  coding: utf-8 -*-
import os.path
import sys
import csv
from io import StringIO 
import xml.etree.cElementTree as ElementTree
from xml.etree.ElementTree import XMLParser
import xml
import xml.sax
from xml.sax import ContentHandler

class MyHandler(xml.sax.handler.ContentHandler):
    def __init__(self):
        self._charBuffer = []
        self._result = []

    def _getCharacterData(self):
        data = ''.join(self._charBuffer).strip()
        self._charBuffer = []
        return data.strip() #remove strip() if whitespace is important

    def parse(self, f):
        xml.sax.parse(f, self)
        return self._result
    

    def characters(self, data):
        self._charBuffer.append(data)

    def startElement(self, name, attrs):
        if name == 'Response':
            self._result.append({})

    def endElement(self, name):
        if not name == 'Response': self._result[-1][name] = self._getCharacterData()

def read_data(path):
    with open(path, 'rU', encoding='utf-8') as data:
        reader = csv.DictReader(data, delimiter =',', quotechar="'", skipinitialspace=True)
        for row in reader:
            yield row

if __name__ == "__main__":
    empty = ''
    Response = 'sample.csv'
    for idx, row in enumerate(read_data(Response)):
        if idx > 10: break
        data = row['E']
        print(data) # The before
        data = data[1:-1]
        data = ""'{}'"".format(data)
        print(data) # Sanity check 
#         data = '<Response TransactionID="2" RequestType="HoldInquiry"><ShareList>0000',0001,0070,</ShareList></Response>'
        try:
            root = ElementTree.XML(data)
#             print(root)
        except StopIteration:
            raise
            pass
#         xmlstring = StringIO(data)
#         print(xmlstring)
#         Handler = MyHandler().parse(xmlstring)


Specifically, due to the quoting in the CSV file (which is beyond my control), I have had to resort to slicing the string (line 51) and then formatting it (line 52).

However the print out from the above attempt is as follows:

"<Response TransactionID="2" RequestType="HoldInquiry"><ShareList>0000'
<Response TransactionID="2" RequestType="HoldInquiry"><ShareList>0000

  File "<string>", line unknown
ParseError: no element found: line 1, column 69
Interestingly - if I assign the variable "data" (as in line 54) I receive this:

  File "<ipython-input-80-7357c9272b92>", line 56
data = '<Response TransactionID="2" RequestType="HoldInquiry"><ShareList>0000',0001,0070,</ShareList></Response>'
                     ^
SyntaxError: invalid token

I seek feedback and information on how to address utilizing the most Pythonic means to do so. Ideally, is there a method that can leverage ElementTree. Thank you, in advance, for your feedback and guidance.
