Parsing : String to XML

Question

my API is supposed to take a string and typecast it to XML format.

But i am consistently getting this error :

ParseError: mismatched tag: line 1, column 764

XML

<?xml version="1.0" encoding="utf-8" ?>
<MasterDetails IssuerId="5" Version="12.2">
    <XMLRequest />
    <BookingDetails  Amount="768"  Comment="Hotel Travel Purchase"  CurrencyCode="INR"  PurchaseType="Hotel"  SupplierName="SomeHotel"  CardAlias="C_ALIAS"  ValidFor="-1D"  CurrencyType="B" />
    <CDFs>
        <CDF FieldName="Order Date" FieldValue="2015-01-01" />
    </CDFs>
    <SomeTag>
        <Rule Action="A" Alias="MyAlias">
            <Controls>
                <OPMCCControl Negate="False"/>
                <OPMIDControl />
                <SomeControlsTags       CumulativeLimit="768"       MaxTrans="None"                 Period="C" />
                <ValidityPeriod           ValidFrom="2015-01-01 00:00:00.0 +0000"          ValidTo="2015-01-11 00:00:00.0 +0000" />
            </Controls>
        </Rule>
    </SomeTag>
</BookingDetails>
<Email  EmailAddress="T@J.COM"/>
<MasterDetails />

Implemented via :

tree = ET.ElementTree(ET.fromstring(kk.strip()))

I know for sure that my XML string is containing all matching tags and is formatted but still something might be missing infront of my eyes!!

"I know for sure that my XML string is containing all matching tags and is formatted" If you had actually run i through a XML validator, you would have seen that this is not the case. — M4rtini, Jan 20 '16 at 06:38
@M4rtini : i was actually formatting it via http://www.webtoolkitonline.com/xml-formatter.html and it formed well....so that was one point of assumption! Also, its minified version of a very large XML :) — NoobEditor, Jan 20 '16 at 06:40

The BookingDetails tag is self-closed on this line:

<BookingDetails  Amount="768"  Comment="Hotel Travel Purchase"  CurrencyCode="INR"  PurchaseType="Hotel"  SupplierName="SomeHotel"  CardAlias="C_ALIAS"  ValidFor="-1D"  CurrencyType="B" />

But when there is a separate closing BookingDetails element:

</BookingDetails>

Also, the <MasterDetails /> is not properly closed on the last line. Should be </MasterDetails> instead of <MasterDetails />.

Note that you can parse this XML in the "recover" mode if lxml.etree is used:

import lxml.etree as ET

parser = ET.XMLParser(recover=True)
tree = ET.ElementTree(ET.fromstring(data, parser=parser))

Or, use BeautifulSoup with xml features:

from bs4 import BeautifulSoup

soup = BeautifulSoup(data, "xml")
print(soup.prettify())

BeautifulSoup!! ET is a pile of junk in comparison, out of the box it just worked! – hounded Sep 11 '18 at 09:24
Note that you can parse this XML in the **recover** mode if lxml.etree.XMLParser is used: `parser = lxml.etree.XMLParser(recover=True) ` – TRINADH NAGUBADI Apr 23 '19 at 06:05
