Hi,

just as a short note, is seems as if either

 a. the regex parser does not work as documented, or
 b. I have somehow messed up.

To be precise, http://www.digitalmars.com/ctg/regular.html says
that "." matches any character. I seem to have found at least
one exception, the newline character "\n".
Example the string "abc\ndef" is not matched by "^\".*\"$",
but is by "^\"(.|\n)*\"$".

Can anyone confirm?

Happy hacking,

	0ffh

It's standard in regex syntax that the dot doesn't match a newline. Should probably have been mentioned in the docs, though.

Usually there's modifier than makes the dot match newlines too, but I can't see one on that page.

Well, that would appear to be the reason, then.
As I have found a trivial workaround, it's just as well.... :)
