converting curl command to a Python3 requests.post (SOAP xml)

I'm trying to get the following command line to work in Python using the 'requests' library: 

curl --header "Content-Type: text/xml;charset=UTF-8" --data @test_GetCapabilities.xml http://www.bom.gov.au/waterdata/services?service=SOS

the curl returns the desired response immediately when executed in Anaconda Prompt from the directory containing the test_GetCapabilities.xml file. But the post request does not work when i run the Python script below. 

import requests
url = 'http://www.bom.gov.au/waterdata/services?service=SOS'
payload = "test_GetCapabilities.xml"
headers = {'Content-Type': 'text/xml', 'charset': 'UTF-8'}
r = requests.post(url, data=open(payload), headers=headers)
print(r.content)

The above code times out after about a minute and gives this stack:

runfile('C:/Python/SOAP_curl.py', wdir='C:/Python') Traceback (most recent call last):

File "", line 1, in runfile('C:/Python/SOAP_curl.py', wdir='C:/Python')

ConnectionError: ('Connection aborted.', BadStatusLine('HTTP/1.1 0 Init\r\n'))

Here is the contents of test_GetCapabilities.xml:

Thanks @kcorlidy.

Here is the corrected working code:

import requests 
url = 'http://www.bom.gov.au/waterdata/services?service=SOS' 
payload = "test_GetCapabilities.xml" 
headers = {'Content-Type': 'text/xml', 'charset': 'UTF-8'} 
with open(payload) as fd: 
    r = requests.post(url, data=fd.read().replace("\n",""), headers=headers) 
print(r.content);
