Extract attribute from XML field in search results

I have a field that contains XML string in my data and I want to, instead of retrieving the full XML, extract a few attributes from it in the final results.

In practice I can do it using Python (query all the needed data > use Python to parse the results), however the heavy data load makes it impossible for me to fetch all the needed data and having someone to parse it beforehand in the server side would take a long wait time.

Is there any way I can parse and extract attributes from XML field during search?
