Thank you very much!
I'm new to Jinja2 and was basing what I could do with it on the
contents of http://jinja.pocoo.org/docs/2.10/templates/. This has no
matches for "regex" so I thought I couldn't do that, and I also
didn't realise that I could use a method of a string object like
"startswith".
I see now that I should have been looking in the Ansible
documentation for filters, i.e.:
http://docs.ansible.com/ansible/latest/user_guide/playbooks_filters.html#regular-expression-filters
Cheers,
Andy
