Best way to process large/complex XML/schema ?

[snippsat]

We know Python is interpreter language.

Is Pyhton the right one to do the above for performance?

What are the option we have ?

Performance is no problem as eg lxml has C speed.

The lxml XML toolkit is a Pythonic binding for the C libraries libxml2 and libxslt.
It is unique in that it combines the speed and XML feature completeness of these libraries with the simplicity of a native Python API

The above input XML messages need to be validated against XML Schema (xsd) for schema comliant

Validation with lxml

The validated XML messages to be parses and extract the data .

I like to use BS for parsing,still same speed as here use lxml as parser.

import requests
from bs4 import BeautifulSoup

url = 'http://httpbin.org/xml'
response = requests.get(url)
soup = BeautifulSoup(response.content, 'lxml')
title = soup.select_one('title')
print(title)
print(title.text)

Output:
<title>Wake up to WonderWidgets!</title>
