Re: [Exist-open] Still trying to validate an XML Schema

[Ted H. <meg...@gm...>]

if I owned a filesystem and a simple webservice, then I would do that.  But
I don't have such things.  All I have is a simple computer and I'm just
someone who experiments with this software at home.  I try to tutor people
on social media.


When I try to open eXide, it shows me an error message.  It says it seem
that another version of eXide has been used from this browser before.  If
you experience any display issues, please clear your browser's cache.  If I
clear my browser's cache, I will clear a lot of things I don't want to
destroy.  Is there some workaround for this?

What about testing with those files stored in a filesystem and served by a
simple webserver?
