Re: multiline rex.match

[Axel Kittenberger <axkibe@...>]

what does ".*?" mean? .* is any character zero or multiple times and
what does the ? add?

Examples are examples. Real code is different. Anywhere they use short
names for example code. A rule of thumb is the broader the context the
more descriptive the name. Local variables can be short.

lua derived itself from a data description language. do you really
need xml? how about sandboxed lua code?

Kind regards,
