Hi

I reviewed this fix and after reading what escape_once does it didn't really make sense that it would work correctly. However, once I actually put some test data through the system it seems to do the right thing in all cases I can figure out.

I then tried removing escape_once and just outputting the line without any escaping, and it seem that HAML already does escaping implicitly.

Probably escape_once can be removed completely to make the template cleaner, but I don't think the extra call actually hurts.

I'm a bit embarrassed that I never tried without it, but you are correct! I guess #114 would reappear though if we removed it since adding :escaped solved that issue. I don't have any nodes with xml output to test with

any chance of bumping the release version on oxidized-web to 0.9.4 because of this fix? This bug is super annoying.

@laf - Can we look at bumping to 0.9.4 for this fix?

I think it's come up on https://community.librenms.org/t/oxidized-configs-quotes-marks-showing-as-quot/1735 as well.

Thanks,

Matt
